Weatherable Coatings for Thermoplastic Substrates

Consumption of automotive plastics in the United States continues to climb and is expected to double by 1999. It is estimated that the average weight of plastic use per automobile will be 300 pounds. This increased use of plastics, both in interior and exterior applications, also increases the importance of developing coatings for plastics.

This paper will disclose the types of coatings used in plastics. In particular, the surface treatmentsutilized and type of coatings applied to obtain weatherable, adhesive coatings to thermoplastic olefins will be discussed.
