Cement, tile mortars and grout are all at risk of damage from cracking and moisture. An addition of styrene-butadiene latex improves flexibility, which helps resist crack formation, but when water is present carboxylated styrene-butadiene latexes like Tylac® are the preferred choice. These work by using a precise addition of carboxylic acid during polymerization to reduce the quantity of surfactant needed and promote polymer cross-linking. Incorporating just a small proportion in a cement or cementitious mix increases water resistance, hardness and adhesion.
When UV resistance is also needed, which is often the case in outdoor applications, turn to the Rovene® family of acrylics. These resist the premature aging that can affect non-acrylic polymers, and also hold up well top attack by oils and solvents, ensuring an as-new appearance is maintained for years.
Rovene 4310 is a medium soft carboxylated styrene-butadiene emulsion designed for formulation of general purpose labels and construction adhesives.
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.
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 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 4545 is a styrene-butadiene emulsion polymer of medium to high stiffness. It dries to form a flexible, tough film of high water resistance.
Rovene 4180 is a low VOC styrene-butadiene emulsion polymer that provides the ability to compound at high solids and in multiple application areas
Rovene 4220 is a non-carboxylated styrene-butadiene emulsion recommended for use in formulations directed at contact or cold seal applications. Rovene 4220 can also be used in architectural adhesives including many types of flooring adhesives and special contact adhesives.
Tylac 873 is a carboxylated acrylonitrile-butadiene copolymer emulsion used in anionic asphalt emulsions to improve low temperature flexibility, reduce high temperature tack, improve strength and chemical resistance.
