During recent years, the emergence of various engineering thermoplastics, coupled with the need to produce more lightweight, fuel efficient cars, has caused plastic materials to find ever increasing use in the automotive industry. Plastics are being used for production of a wide variety of automotive parts, including interior, exterior, and under the hood components. Many of these plastics, particularly exterior parts (i.e., bumpers and fascias), are quite flexible in nature, and thus require extremely flexible coatings to decorate and protect them. This flexibility requirement, coupled with various other performance and regulatory requirements, such as increased hardness, environmental etch resistance and lower solvent emissions, have led to considerable efforts in the developments of plastic coatings. Two-component, flexible polyurethane coatings are used as protective and aesthetic coatings for many automotive plastic applications. Adjusting the coating flexibility to match the flexibility of the plastic allows the coated plastic to retain the impact resistance of the uncoated plastic. New developments in polyurethane chemistry allow the formulation of coatings with much lower VOC's than conventional flexible polyurethanes. These low VOC, flexible, polyurethane coatings exhibit improved room temperature polishability. This technology also shows the potential to yield coatings with improved environmental etch resistance.
