BarrierPro® 4551

CARBOXYLATED STYRENE-BUTADIENE EMULSION

Product Description

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.
