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 an example formulation for an acrylic latex emulsion adhesive that can be used as a mastic adhesive for ceramic floor tiles. The latex adhesive dries to a somewhat rubbery film, which has good resistance to water and good adhesion to most substrates including wet concrete surfaces.
