Applicable Base Polymer Properties

Acrylic solvent solutions offer an adhesive with excellent overall performance properties. Acrylic resins are tremendously versatile due to the large number of different monomers and resins available. Acrylic 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. Solvent-based acrylic adhesives provide somewhat better chemical and heat resistance than water borne acrylics.

Resulting Properties

Acrylic solutions are used on a large scale for laminating high-gloss films, e.g., acetate films or cellophane, to pocket books, record covers, etc. Laminates of aluminum foil and paper having good resistance to heat and water can also be made with acrylic adhesives. Typical formulations are shown in Table 4.
