Applicable Base Polymer Properties

Acrylic thermoplastics 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 or hot melt based acrylic adhesives provide better chemical and heat resistance than water borne acrylics.

Resulting Properties

Elvacite 2044 is one of the softest and tackiest of the Elvacite resins. It is the preferred grade for many specialty adhesive applications, particularly for bonding coated “Mylar” polyester film and other nonporous plastic films and foil. The above formula is suggested as a heat-seal adhesive for paper. Elvacite 2044 resin also finds use in specialized adhesive applications where clarity and light-fastness are required. The solvent systems can be adjusted readily for ease of handling on conventional adhesive applicators.
