High Solids Polyurethane Coatings for Automotive Plastics

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.
