A Cost Effective Quality Improvement for Automotive Glass Encapsulation

Light stable polyurethane elastomers, based on aliphatic diisocyanates, have been successfully used in the production of encapsulated automotive glass since 1987. The ultraviolet and weather resistance inherent in these polyurethane polymers have made them the material of choice for many modular windows, both in Europe and the United States. Since the selection of these materials is based largely on their superior field performance, this paper will review a variety of long term durability test data. This data will be of interest to two types of people: 1) engineers designing products which must meet new long term trim warranties 2 manufacturers wishing to eliminate the processing problems and environmental concerns of paint from their production operations.
