Adhesive made of polymers having crystalline domains, amorphous polyurethane and silane compounds
Abstract:
A description is given of an adhesive comprising two components, the first component comprising at least two different polymers of which at least one contains carboxyl groups. One of the polymers is selected from polymers which are capable of forming crystalline domains and copolymers of ethylene and vinyl acetate, and the second polymer is an amorphous polyurethane, the quantitative weight ratio of first polymer to second polymer being from 2:8 to 8:2. The second component comprises at least one silane compound that is reactive toward carboxyl groups. The adhesive can be used to produce film-laminated moldings for automobile construction which feature high resistance to climatic cycling.
