Rovene 9423 Carboxylated styrene-butadiene rubber Ameripol Synpol-Mallard Creek Polymers Styrene copolymer >> Styrene butadiene emulsions ADHESIVE >> Water-based >> Pressure sensitive (PSA) ROVENE® 9423 is a very soft carboxylated styrene - butadiene (SBR) latex emulsion specifically designed for formulation of permanent label adhesives. Its relative high molecular weight and styrene content (35%) allows the formulation of permanent label adhesives which are high in peel and tack, yet require a minimum amount of tackifier. it was designed to give excellent performance and compatibility with a wide variety of dispersed tackifiers. ROVENE® 9423 is recommended for pressure sensitive permanent label adhesives and blended with natural latex for high shear tape adhesives. Very soft, relative high molecular weight, carboxylated styrene butadiene latex emulsion. Used in the formulation of pressure sensitive permanent label adhesives and in high shear tape adhesives when blended with natural latex. Provides high peel and tack. Requires minimum amount of tackifier. Gives very good performance and compatibility with a wide variety of dispersed tackifiers. Possesses an anionic emulsifier.
