BarrierPro

BarrierPro 4550 is a general purpose styrene-butadiene emulsion polymer of medium stiffness. It dries to form a flexible, tough film of high water resistance. BarrierPro 4550 can be compounded with fillers and other additives to form coatings for a variety of applications such as water proofing membranes, specialty paints and sealants.

BarrierPro 4551 is a carboxylated styrene-butadiene emulsion with excellent strength properties, high resistance to liquid water and water vapor, high blush resistance and excellent adhesion to multiple construction substrates. BarrierPro 4551 has excellent stability with dry-add inorganic fillers and sets quickly into a low tack, high strength, water resistant film. BarrierPro 4551 is also a good base polymer for blending with other BarrierPro products to allow a membrane to be custom tailored to a specific strength and/or flexibility need.

BarrierPro 4555 is a styrene-butadiene emulsion polymer of low stiffness. It dries to form a soft but tough film. Its softness makes it excellent for water proofing where films must remain flexible at below-freezing temperatures. Features: Highly stable Cured films are tough and flexible below freezing temperatures Cured films have good water resistance Hydrolysis resistant Filler compatible
