UV stabilisation of powder clear coats

Powder coatings are gaining importance in exterior applications such as automotive and architectural finishes. The use of additives in powder coating formulations enhance the durability of the coating by reducing the effects of harmful UV light and providing high temperature stability during processing and curing. Customers' increased demands for better retention of aesthetical and mechanical properties has prompted the development of new additives dedicated to powder coatings. This paper presents an overview of the performance of light stabilizers used in powder coatings.
