DION 9102 CURING
The DION 9102 products are unpromoted vinyl ester resins for use with cobalt naphthenate, or octoate, and an
aniline accelerator which responds well to MEKP catalyst systems. Other catalysts work as well, but should be
thoroughly evaluated prior to use. These resins however, are sensitive to low temperatures and care must be
taken to avoid less than minimum stated quantities of MEKP type catalysts.
At temperatures below 60°F, it may be necessary to add dimethylaniline in incremental amounts of 0.05 phr to
increase gel and cure profiles. For applications at high ambient temperatures (80-90°F) the MEKP catalyst levels
must still be maintained above the minimum recommendation to achieve optimum cure. In order to lengthen gel
times at these temperatures, it is suggested that the MEKP catalyst be maintained at 1.25 phr and the gel time be
adjusted with additions of tert-butyl catechol solution (TBC-10) or low levels of 2,4 pentanedione (PDO).
The DION 9102 products can also be effectively cured using a benzyl peroxide (BPO) / dimethylaniline (DMA)
system. Note: BPO/DMA systems are not authorized for use in NSF/ANSI 61 situations.
GUIDELINES FOR DION 9102 SERIES RESINS ● INITIATOR AND PROMOTER ADDITIONS
(NOT TO BE USED IN NSF/ANSI 61 APPLICATIONS – REFER TO PAGE 3 FOR REQUIREMENTS IN THESE
APPLICATIONS)
Add cobalt naphthenate and dimethyl aniline in quantities shown to achieve working life at the temperature
indicated. Resin gel time will drift slightly if allowed to stand overnight. Readjust with additional DMA.

2 Caution: Excessive cobalt can inhibit cure and degrade corrosion resistance. Do not use more than 0.5% of
cobalt 6% or 0.25% of cobalt 12%. If using cobalt octoate (12%), use half of the amount indicated in the chart
for cobalt 6%.
3 Witco HiPoint™90 or equivalent. HiPoint 90, Lucidol™ DHD-9 and Trigonox™ 239A have proven to be
particularly well suited for curing DION vinyl ester resins. Trigonox 239A has been shown to reduce or eliminate
foaming upon initiator addition, but may not adapt to the above cure grids. Other brands of MEKP have also
been used successfully. A thorough evaluation of initiator characteristics is suggested prior to fabrication to
satisfy user’s expectations.
WARNING: CARE MUST BE TAKEN TO AVOID DIRECT MIXING OF ANY ORGANIC PEROXIDE WITH
METAL SOAPS, AMINE OR ANY OTHER POLYMERIZATION ACCELERATOR OR
PROMOTER, AS VIOLENT DECOMPOSITION WILL RESULT!

EXTENDED AMBIENT CURING TIME WITH DION 9102 USING 2,4 - PENTANEDIONE (PDO)
(NOT FOR NSF/ANSI APPLICATIONS)
Due of the unique manner in which vinyl ester resins reacts when small amounts of 2,4-Pentanedione (PDO) are
added, it is possible to extend the ambient temperature gel time of these resins without greatly affecting their peak
exotherm and gel-to-peak profile. The following charts and graphs show ambient gel time data for various levels
of 2,4-PDO at different temperatures.

chart was Norac 46727 CHP at 1.25% (by weight).
4 Other gel tests were run using higher levels of 2,4-PDO. Results indicate that gel time will not lengthen
significantly beyond the 0.9% level. The 2,4-PDO may actually begin to act as a promoter or plasticizer.

DION 9102 PARAFFINATED TOPCOATS
Even fully cured resin of a non-mold sided surface can demonstrate some tackiness due to air inhibition. Surface
cure may be improved by incorporating a paraffin wax into the resin to be used in the final ply. Alternatively, a
wax modified resin can be added as a protective topcoat once the laminate has hardened. These topcoated
surfaces will negatively influence secondary bonding. Grinding and additional surface preparation will
become necessary to enhance the success of the bond.
