Abstract
A chemical composition and method of applying same between glass and attached layer(s) of polyester or other plastic safety/security films to enhance the bonding of the applied adhesive therebetween as well as the strength of the glass laminate construction. In a preferred embodiment, the chemical composition is an acrylic-based mixture, containing alcohol, glycol, a slip agent, and a wetting agent. In an alternative preferred embodiment, the chemical composition is a silane-based mixture, containing alcohol, glycol, and a slip agent. The preferred embodiments of the invention are used in combination with currently available glass laminate systems to enhance the bonding and adhesion thereof.
