Applicable Base Polymer Properties

Acrylic emulsions offer a low cost adhesive with moderate performance properties. They are tremendously versatile due to the large number of different monomers and resins available. Acrylic waterborne laminating adhesives can provide bonds ranging from flexible and tough to hard and rigid depending on the formulation. Acrylic adhesives inherently have very good UV and oxidative stability and are generally preferred for outdoor applications.

Resulting Properties

The table above provides a typical starting formulation for a clear pressure sensitive acrylic adhesive that can be used with clear film and paper labels for packaging applications. Encor 9466 is a high solids, coater ready, inherently pressure-sensitive acrylic copolymer emulsion. This polymer offers excellent peel and tack adhesion with exceptional cohesive strength. The versatility of the polymer allows the converter to use the product as is for general purpose applications or formulate for specialty applications.
