Maximizing Adhesion of Waterborne Acrylic PSAs

SpecialChem / Edward Petrie – Sep 22, 2004

Pressure sensitive adhesives are mainly classified into three types: waterborne, hot melt, and solvent borne. The waterborne and hot melt technologies dominate the market due to the environmental concerns and government regulations relative to solvent emissions. Of the waterborne pressure sensitive adhesives (PSAs), acrylic polymers are important products with superior properties to many other polymers. The inherent pressure sensitive characteristics of acrylic PSAs were realized in 1929; however, polyacrylates only secured their present prominent commercial position in the 1960s. In this article, we will discuss methods of maximizing the adhesion properties of waterborne acrylic PSAs. Such modifications are generally obtained by control of properties such as tack, peel, and shear strength. The review will concentrate on (1) the formulation of waterborne acrylic PSAs as well as on (2) non-formulation (end-user) criteria that are important in achieving maximum bond strength.
