Ambient cure high solids acrylic resins for automotive refinish clear coat applications

摘要

There is nowadays an increasing demand for low VOC systems in automtive refinish industry. These systems should also cure sufficiently fast at ambient temperature in order to reduce the investment in drying equipment and the time of repair. However, matching the stringent chemical and mechanical requirements associated with medium solids systems, and reaching a VOC level < 420 g/1 (from the UK and Dutch lengislation) is a challenge, especially if the coatings are cured at room temperature.
