Disclaimer:
Due to its cationic nature, formulations based on SYNTRAN cationic polymers should not be mixed with paints based on ani-
onic binders. SYNTRAN cationic polymers are not stable at alkaline pH.
SYNTRAN 6301 and FX30-20 both contain formic acid. Formulated coatings should not be used on metal or other surfaces
subject to acid corrosion as the coating is drying. After curing, the coating is safe for all surfaces.

TANNIN BLOCKING COATING BASED ON SYNTRAN® FX30-20
Formulation F-43-048-01 25% N.V.
The SYNTRAN FX30-20 tannin blocking coating formulation is designed to fill and seal
wood pores completely and to prevent tannin stains in new wood before applying a
topcoat. This quick-drying sealer formulation sands easily to a smooth surface for
even topcoating.
SYNTRAN FX30-20 contains formic acid. The sealer, tannin blocking coating should
not be used on metal surfaces and should be allowed to completely dry before anionic
topcoats are applied.

Selected Application Test Results
(1) Nicotine Stain Blocking
Top: Stained substrate covered with a conventional water-based paint. Bottom: As above, but with an addi-
tional applied, non-pigmented primer based on SYNTRAN 6301. For accelerated staining, samples were
exposed to 40oC and 100% rel. humidity for two days.
(2) Blocking of a Water-Based Wood Stain
Left: Stained wood substrate covered with a non-specialized, white, water-based primer and topcoat system.
Severe bleeding is observed. Right: Same as on left side, but using a white stain-blocking primer based on
SYNTRAN 6301. Here, even the primer shows no discoloration. (Note: In the lower parts of the photo, the
substrate was covered with the primers only, whereas in the upper parts the primer/topcoat systems were
applied).

(3) Tannin Stain Blocking on Framire Wood
Left: Application of a white, non-specialized, water-based primer. The yellow discoloration indicates severe
tannin bleeding. Right: Application of a white stain-blocking primer based on SYNTRAN 6301. Even when
applied in a single coat, discoloration due to wood extractives can be prevented.
(4) Tannin Stain Blocking on White Oak
Left: Application of a white, non-specialized, water-based primer. The yellow-brownish discoloration indi-
cates severe tannin bleeding. Right: Application of a white stain-blocking primer based on SYNTRAN 6301.
Even when applied in a single coat, discoloration due to wood extractives can be prevented.

(5) Stain Blocking on Cork
Left: Application of a white, non-specialized, water-based primer. The spotted, brownish discoloration indi-
cates severe bleeding of extractives. Right: Application of a white stain-blocking primer based on SYNTRAN
6301. Even when applied in a single coat, discoloration due to extractives can be prevented.
(6) Graffiti Stain Blocking
Left: Substrate stained with (from top to bottom) graffiti from red text marker, yellow text marker, black ball-
point pen and blue OHP-pen. Middle: Graffiti stained substrate after application of a conventional, water-
based, white paint. Severe bleeding is observed. Right: Same as in the middle, but with an additionally
applied, non-pigmented stain blocking primer layer based on SYNTRAN 6301.
