Complete technical information and literature are available from GE - Silicones. Laboratory facilities and application engineering are available upon request from GE - Silicones. SilPruf SCS2000 sealant & adhesive should not be applied or used: • In structural glazing applications unless GE - Silicones has reviewed shop drawings for applicability and has performed adhesion and compatibility tests on project substrates, spacer materials and all accompanying accessories. Review and testing is done on a project-by-project basis. No blanket approval is given by GE - Silicones for structural glazing applications. Structural glazing industry guidelines (ASTM C1401) suggest that drawings and details are to be reviewed by all parties involved in the manufacture of an SSG system and for each building project. • Under exceedingly hot or cold conditions (see Sealant Application section for additional information). • On wet, damp, frozen or contaminated surfaces. • On excessively basic or acidic substrates. • In exceedingly large structural cavities (see Sealant Application section for additional information). Precautions • This material requires atmospheric moisture to cure from paste to rubber and may not attain its listed final cured rubber properties when used in designs or applications where the silicone is encapsulated and without access to atmospheric moisture. • When sealing against natural stones, GE - Silicones recommends that stain testing be performed prior to use to ascertain the visual acceptability of the sealant-stone combination. GE - Silicones recommends evaluation of SilPruf NB SCS9000 when sealing to natural stones. • Some materials that bleed plasticizers or oils can cause a discoloration on the surface of sealants. When sealing to or over items such as: rubberized gaskets, bituminous-based materials, butyl or oil-based products, oily woods, tapes, etc., GE - Silicones recommends that compatibility testing be performed prior to use to confirm the suitability of the use of these materials when in contact with each other. • Silicone materials are hydrophobic in nature and if inadvertently over-applied onto adjacent joint surfaces (even if removed immediately), can create a waterproofing effect on some substrate types when the substrate is wet. See section on Masking.

ASTM C1472 Standard Guide for Calculating Movement and Other Effects When Establishing Sealant Joint Width. 4.) ASTM C1401 Standard Guide for Structural Sealant Glazing 5.) SWR Institute’s Applying Liquid Sealants Applicator Training Program. Joint Designs and Dimensions - WEATHERSEALING Joint Movement - The dimensions of joints in typical construction applications change daily as a result of solar heat gain and building sway, and throughout the year due to seasonal changes. The movement in a sealant bead installed on the sun-side of a building or during the hottest portion of the day will be almost entirely in extension during the cold season or cycle; while the movement of a bead installed during the coldest condition will be almost entirely in compression during the hotter season or cycle. In addition to these above movements, the designer should consider the effect of construction tolerances in his/her project to minimize the occurrence of over-sized or under-sized joints during construction. All moving (dynamic) joints must be designed so as not to allow three-sided adhesion of the sealant to occur (reference ASTM C1193). Threesided adhesion hinders the ability of the sealant to extend and compress freely as desired and can lead to early joint failure. Joint Width - When using SilPruf SCS2000 sealant & adhesive, the designed joint width must be at least twice the total anticipated joint movement. For example, if the total anticipated movement in an expansion joint in which SilPruf SCS2000 sealant & adhesive is to be installed is 1/4”, the designed joint width must be at least 1/2”. The designer may want to consider additional width to accommodate construction tolerances (reference ASTM C1472). Large panels or lites should allow a minimum width of 1/4” for the sealant bead, mostly to allow for a proper installation (very small/ narrow beads become difficult to install and can accommodate less movement). Glazing of plastic or larger-sized metal panels may require larger than usual joint widths due to the greater movement potential (higher coefficients of thermal expansion). Consult with GE - Silicones Technical Services for recommendations on large or unusual applications. P. 05 GE - Advanced Materials SilPruf* SCS2000 silcone sealant & adhesive Joint Designs and Dimensions - WEATHERSEALING (continued) Butt Jointing - A thin installation of silicone sealant can better accommodate more movement than a deep installation, as the deeper bead will result in additional stress being imposed on both the sealant and the bonding surfaces during joint movement. Figure 1 illustrates the general guidelines for installation of SilPruf SCS2000 sealant & adhesive into a typical butt joint configuration of widths up to 2”. 1.) The recommended sealant profile is an hourglass shape with the depth of the sealant over the crown of the backer rod to be no thinner than 1/8” and no thicker than 3/8”, and 2.) A minimum of 1/4” of adhesive bonding contact must be made to all surfaces to which the sealant is intended to adhere. When used in joints exceeding 2” in width: 3.) The recommended sealant profile is an hourglass shape with the depth of the sealant over the crown of the backer rod to be no thinner than 1/4” and no thicker than 3/8”, and 4.) A minimum of 3/8” of adhesive bonding contact must be made to all surfaces to which the sealant is intended to adhere. Figure 1 JOINT WIDTH 1/4'' MINIMUM ADHESION CONTACT DEPTH OVER CROWN OF BACKER 1/8'' MIN TO 3/8'' MAX Joint Backer Materials Backer materials, typically backer rod, provide the following benefits to aide in the correct application of SilPruf SCS2000 sealant & adhesive. 1.) To control and provide the desired sealant depth. 2.) Create a formed joint cavity that allows for the desired hourglass sealant shape. 3.) Provide a firm backup which helps attain full wetting of the substrates when the sealant is tooled. 4.) Act as a bond breaker to eliminate adhesion on the backside of a joint (three-sided adhesion). P. 06 GE - Advanced Materials Non-gassing polyethylene, polyolefin or polyurethane foam rod is the recommended back-up material for use with SilPruf SCS2000 sealant & adhesive. If the joint is too shallow to allow foam rod, use a polyethylene tape (as a bond breaker to eliminate three-sided adhesion). On EIFS and porous substrate applications, a closed cell backer rod is recommended (open cell backer materials absorb and hold water which can affect long-term sealant adhesion on these materials). Backer rod should be 25-50% greater (confirm with manufacturer of backer rod as to type selected) than the width of the joint, thereby providing continuous pressure against the joint walls, and expanding and contracting with the joint movement without pushing the sealant out of the joint during the compression cycle or falling away during the extension cycle. Rubber backup materials may stain the sealant and are not recommended, unless tested and verified for compatibility. Joint Designs and Dimensions STRUCTURAL GLAZING • Silicone contact width and thickness (see Figure 2) will vary by project with the design wind load and glass size. • Contact Width can be calculated using the following formula: [Design Wind Load (PSF) x Longest Short Span of Glass or Panel (Ft.)] divided by 480. • A minimum sealant thickness of 1/4” (7mm) between substrates is required to accommodate thermal expansion and contraction (see Figure 3) of most systems and should be used in order to assure that sealant can be injected into the structural cavity obtaining full contact with both the glass and metal surfaces while remaining free of air voids. Greater joint thickness may be required to accommodate movement in some larger-sized SSG systems. GE - Silicones can be contacted to assist in determination of proper joint thickness to accommodate expected movement in structurally glazed applications. The following materials are required to be submitted to GE - Silicones to receive suggestions for the use of SilPruf SCS2000 sealant & adhesive. • Architectural and shop drawings for review and comment. • Design wind load requirement(s) for project. • Glass or panel sizes. • Production samples of metal, glass, gaskets, spacers and setting blocks with type and manufacturer identified. • Specification and/or identification of paint or finish to which SilPruf SCS2000 sealant & adhesive is intended to adhere (i.e., 215-R1 anodized or if paint; manufacturer, finish system and ID#). SilPruf* SCS2000 silcone sealant & adhesive Joint Designs and Dimensions STRUCTURAL GLAZING (continued) GE - Silicones will provide the following, after reviewing the materials above: • Determination as to whether the submitted joint dimensions meet the minimum design criteria necessary for the use of SilPruf SCS2000 sealant & adhesive. • Short-term adhesion data using (typically) the ASTM C794 and/or ASTM C1135 test method. Other test methods may be employed. • Short-term compatibility test results on gaskets, spacers and setting blocks and other accessories per ASTM C1087 or GE - Silicones test method for compatibility. • Information regarding suggested primers, when required. Figure 2 DEPTH (THICKNESS) STRUCTURAL SILICONE CONTACT WIDTH HORIZONTAL SECTION Figure 3: Movement from thermal expansion and contraction and/or glass rotation P. 07 GE - Advanced Materials GE - Silicones will not: • Design sealant joints. • Provide comments on the structural integrity of overall framing system(s). • Provide long-term performance data. The design professional has final responsibility for the determination of structural sealant joint dimensions based on project conditions, design wind load(s), glass or panel sizes, anticipated thermal, seismic or other movement of the system. The ASTM C1401 Standard Guide for Structural Sealant Glazing provides a thorough overview of design topics and information for use in SSG systems. SilPruf* SCS2000 silcone sealant & adhesive Installation Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application. Using proper materials and following prescribed surface preparation and cleaning procedures is vital for sealant adhesion. IN ALL CASES IT IS IMPORTANT TO CONFIRM THE ACCEPTIBILITY OF EACH SEALANT-SUBSTRATE COMBINATION WITH A LAB OR SITE ADHESION TEST PRIOR TO PROCEEDING WITH PROJECT INSTALLATION. GE - Silicones can provide lab and field adhesion testing information and suggestions to user upon request. Surface Preparation Porous Materials (Concrete, Masonry, Brick, Stone, etc.) • Joints must be clean, dry and sound prior to application of the sealant. All contaminants, impurities, or other adhesion inhibitors (such as moisture/frost, oils, concrete form release agents, old sealants, asphalt and other surface treatments, etc.) must be removed from the surfaces to which the sealant is intended to adhere. • Clean where necessary by wire brush, mechanical abrading, grinding, sanding, saw cutting, blast cleaning (sand or water), or a combination of these methods to provide a stable clean surface for sealant application. • Remove dust and other remaining loose particles with a soft bristle brush or by using an oil-free air blow. • Polished stone surfaces and smooth sawn edges can be cleaned using a solvent dampened rag (allow sufficient time for solvent to evaporate prior to application of the sealant). When handling solvents, refer to manufacturer’s MSDS for information on handling, safety and personal protective equipment. • Cleaning of surfaces should be done within 1 to 2 hours of when the sealant is to be applied. • Since porous materials can absorb and retain moisture, it is important to confirm that substrates are dry prior to application of the sealant. P. 08 GE - Advanced Materials Non-Porous Materials (Glass, Metals, Plastics, Ceramics, etc.) • Clean by using a two-rag wipe technique → wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface BEFORE it evaporates (allowing the solvent to dry on the surface without immediately wiping with a second cloth can negate the cleaning procedure because the contaminants may simply be re-deposited as the solvent dries). In all cases where used, solvents should be wiped dry with a clean, white cloth or other lint-free wiping materials. Change the cleaning rags frequently, as they become dirty. It is easier to see the dirt accumulating on the rag if white rags are used. Do not dip used cleaning rags into the cleaning solvent as this can contaminate the solvent (cleaning with contaminated solvent can result in sealant adhesion issues). Always use clean solvent-resistant containers for solvent use and storage. • When cleaning deep, narrow structural glazing cavities, wrap the cleaning cloth around a clean, narrow-blade putty knife. This permits force to be applied to the cleaned surface. • Isopropyl Alcohol (IPA) is a commonly-used solvent and has proven useful for most non-porous substrates encountered in architectural construction applications. Xylene and Toluene have also been found useful on many substrates. When handling solvents, refer to manufacturer’s MSDS for information on handling, safety and personal protective equipment. • Architectural coatings, paints and plastics should be cleaned with a solvent approved by the manufacturer of the product or which does not harm or alter the finish. • Cleaning of surfaces should be done within 1 to 2 hours of when the sealant is to be applied. • Difficult or nearly impossible to see on a joint substrate, frost is likely to develop on substrates when temperatures drop near the freezing point. Since frost and moisture will interfere with proper sealant adhesion, it is important to confirm that substrates are dry prior to application of the sealant. SilPruf* SCS2000 silcone sealant & adhesive Surface Preparation (continued) Sealant Application - WEATHERSEAL Exterior Insulation and Finish Systems (EIFS) • Apply sealant in a continuous operation, horizontally in one direction and vertically from the bottom to the top of the joint opening, applying a positive pressure adequate to properly fill and seal the joint width. • Tool or strike the sealant with a concave tool applying light pressure to spread the material against the back-up material and the joint surfaces to ensure a void-free application. • In glazing applications, tool the sealant at the sill so that precipitation and cleaning solutions will not pool. • Excess sealant should be cleaned from glass, metal and plastic surfaces while still uncured. On porous surfaces the excess sealant should be allowed to progress through the initial cure or set-up. It should then be removed by abrasion or other mechanical means. • Due to the smooth consistency of SilPruf SCS2000 sealant & adhesive, tooling agents such as water, soap, or detergent solutions are not necessary or recommended. Dry tooling is recommended. • Sealant application is not recommended when the temperature is below 40°F (4°C) or if frost or moisture is present on the surfaces to be sealed. • Application of SilPruf SCS2000 sealant & adhesive is not recommended to surfaces above 122°F (50°C). • The cure rate of this product is dependent upon temperature and the availability of atmospheric moisture. Under Standard Conditions (relative humidity of 50 ±5% at an air temperature of 73.4 ±2°F [23 of ±1°C]) this material can attain a cured thickness of 2-3 mm per 24 hours (assuming ample access to atmospheric moisture). As temperature decreases, the cure rate slows down (and vice versa). Low moisture environments will also reduce the cure rate. Near-confined spaces which limit the overall access to atmospheric moisture will cure only from that surface which has access to the atmosphere. Colder temperatures can significantly increase cure times and can open the possibility of sealant irregularities if joint movement occurs while sealant is not fully cured. The following reference provides additional information on Movement-During-Cure of sealant joints: ASTM C1193 - Standard Guide for Use of Joint Sealants; section 12.5. • The use of an appropriate silicone primer is required on all EIFS substrates. Consult GE - Silicones Technical Services for sealantprimer-substrate recommendations. • Confirm with the EIFS supplier which finish the sealant should be applied to (i.e., base coat or base coat with EIFS primer). • All EIFS surfaces must be clean, dry and sound and in an acceptable condition to receive sealant. Confirm with the EIFS supplier or project architect or consultant, what joint conditions are considered acceptable for sealant installation to proceed. If unacceptable conditions are found, cease installation of sealant until corrections are made. • To clean EIFS, lightly abrade the joint surfaces using a synthetic brush or pad and then remove dust and other remaining loose particles with a soft bristle brush or using an oil-free air blow. • Cleaning of surfaces should be done within 1 to 2 hours of when the sealant is to be applied. • Since EIFS materials can absorb and retain moisture, it is important to confirm that the EIFS materials are dry prior to application of the sealant. Priming SilPruf SCS2000 sealant & adhesive attains primerless adhesion to many commonly encountered construction materials. However, some materials with variable surface characteristics may require the use of a primer to help obtain durable long-term adhesion. Prior to use, trial applications should be made to check adhesion to the specific materials to be used on the project. See the GE - Silicones primer datasheets for product specific information on use and priming instructions. PRIMER APPLICATION IS NOT A SUBSTITUTE FOR SURFACE PREPARATION. Consult GE - Silicones Technical Services for sealant-primer-substrate recommendations. CAUTION: Primers may contain solvents. When handling solvents, refer to manufacturer’s MSDS for information on handling, safety and personal protective equipment. Masking The use of masking tape is recommended where appropriate to ensure a neat job and to protect adjoining surfaces from overapplication of sealant. Masking tape can prevent contact of sealant with adjoining surfaces that otherwise would be permanently marred or damaged by such contact or by cleaning methods required to remove sealant systems. When tooling, use care not to spread the sealant over the face of the substrates adjacent to the joint or masking as the silicone can be extremely difficult to remove on rough or porous substrates. Do not allow masking tape to touch clean surfaces to which the silicone sealant is to adhere (adhesive on masking tape can interfere with adhesion of silicone). Masking tape should be removed immediately after tooling the sealant and before the sealant begins to skin over (tooling time). P. 09 GE - Advanced Materials SilPruf* SCS2000 silcone sealant & adhesive Sealant Application - STRUCTURAL GLAZING • Apply the sealant by pushing the bead ahead of the nozzle and making sure that the entire cavity is filled. Tooling should be done neatly, forcing the sealant into contact with the sides of the joint, thus helping to eliminate any internal voids and assuring good substrate contact. AIR POCKETS OR VOIDS WITHIN THE STRUCTURAL CAVITY ARE NOT ACCEPTABLE. • Due to the smooth consistency of SilPruf SCS2000 sealant & adhesive, tooling agents such as water, soap or detergent solutions are not necessary or recommended. Dry tooling is recommended. • Sealant application is not recommended when the temperature is below 40°F (4°C) or if frost or moisture is present on the surfaces to be sealed. • SilPruf SCS2000 sealant & adhesive works best when applied to surfaces below 122°F (50°C). • SilPruf SCS2000 sealant & adhesive should not be applied in totally confined spaces since the sealant requires exposure to air a to cure properly and develop typical properties. In a typical SSG cavity, cure depths up to 3/4” from an air interface will generally cure satisfactorily and reach maximum properties within several days. Cure depths > 3/4” may take significantly longer time to cure and when applied in a single application may not cure satisfactorily. Consult GE - Silicones technical services for additional information on depth of cure for this product. Method of Application SilPruf SCS2000 sealant & adhesive is easily dispensed directly from cartridges and foil sausage packs using standard caulking guns or from 2 gallons pails using standard bulk caulking gun equipment. The sealant may also be dispensed from 55 gallon drums with pumping equipment.
