The document discusses future trends in automotive coatings. It describes the evolution of coating systems from the 1970s to present day and projections to 2020. Compact coating processes are highlighted as market drivers to reduce cost and improve durability, environment, and sustainability. Examples of waterborne compact processes using B1/B2 layering or 3C1B configurations are presented. The premium compact process is identified as a best practice approach, providing appearance of full systems while improving economy and ecology. The future of coatings is said to involve fusion layer substrates, alternative pretreatment technologies, and multi-substrate capabilities.
