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.
