Hot melt adhesive composition for bonding a locator pin to glass

摘要

The present invention provides an adhesive composition comprising a uniform mixture of components, the components comprising a first and a second thermoplastic polyurethane, the first thermoplastic polyurethane being a thermoplastic polyurethane of which the shear tan delta versus temperature curve approaches infinity at a temperature above 150° C. and that has a glass transition temperature of not more than 10° C., the second thermoplastic polyurethane having a softening point of not more than 80° C. and the adhesive composition being solid at a temperature of 20° C. and being capable of bonding to glass or a ceramic frit layer provided on glass at a temperature between 100° C. and 160° C. The present invention further provides a method for bonding a locator pin to a window glass using the adhesive composition and further a locator pin having the adhesive composition.
