Abstract
An adhesive composition containing a linear polyester polyurethane, a halogenated polyolefin, an epoxy/silane adduct, a Diels-Alder adduct of a halogenated cyclic conjugated diene and a block copolymer of styrene and butadiene and a crosslinking compound for the linear polyester polyurethane. The adhesive composition is preferably utilized as a two-component adhesive for bonding vinyl polymers such as polyvinyl chloride to various substrates such as glass. The adhesive composition exhibits substantial resistance to environmental conditions without the requirements of a pre-heating step.
