Rovene® 4423


Rovene 4423 is a very soft carboxylated styrene-butadiene emulsion designed for formulation of permanent label adhesives and flooring adhesives. This polymer emulsion allows for the formulation of permanent label adhesives which are high in peel and tack, yet require a minimum amount of tackifier. However, it provides good tack on its own, thus minimizing the amount of tackifer required.


Rovene 4423 was designed to give excellent performance and compatibility with a wide variety of dispersed tackifiers. Rovene 4423 can also be blended with natural latex for high shear tape adhesives and for use in special contact adhesive applications.
