Evaluation of Low-Solvent Automotive Refinishing Coatings

摘要

Automotive coatings supplied to Original Equipment Manufacturers (OEM) and forautomobile repainting are estimated to reach 144 million gallons by 1993. The enormous problem of volatile organic compound (VOC) emissions which accompanies this growing volume of coating usage has led to developing technologies such as water-based, high-solids and multiple-component systems which are replacing conventional low-solids high-VOC coatings. The study compares the physical, compositional and performance properties of emerging technology coatings to those of existing coatings non-compliant with Bay Area and South Coast Air Quality Management District rules. All of the coatings evaluated were ranked in accordance with a set of ten weighted criteria. The performance properties of some VOC-compliant coatings equal or exceed those of non-VOC compliant coatings used for the same purpose.
