CARBOXYLATED STYRENE-BUTADIENE EMULSION
May be used either alone (for a strong but less flexible membrane than with BarrierPro 4550) or as a blend with softer BarrierPro polymers to enhance stiffness and strength.
BarrierPro® 4545 is a general purpose latex binder of medium to high stiffness. It dries to form a flexible, tough film of high water resistance. BarrierPro® 4545 can be compounded with fillers and other additives to form coatings for a variety of applications. Because of its high strength film, it makes an excellent product for blending with other BarrierPro® products to strengthen damp proof membranes, specialty paints and sealants.
