PRODUCT FEATURES AND APPLICATIONS
*  UV 928 is a new UV absorber of the hydroxyphenyl benzotriazole class developed specially for high performance coating applications.
*The broad band absorption of  UV 928 provides efficient protection to coatings and light sensitive substrates.
*  UV 928 has excellent solubility and high thermal and environmental permanence, which makes it particularly suitable for coatings exposed to high temperature curing processes, such as powder and coil coatings
*  UV 928 is recommended for applications such as:
automotive coatingspowder and coil coatings
* The use levels of  UV 928 range between 1 and 3%, depending on application.
*  UV 928 can be used in combination with HALS to optimize performance in outdoor use.
