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.
