2. Features:RU-6380H is a UV resin with medium performance, high reactivity, and high molecular weight for plastic spraying. Its main characteristics are to improve the leveling state, eliminate surface defects such as pitting, pinholes, and orange peel in the coating, and improve the surface cleanliness and other comprehensive properties of the coating. It has excellent adhesion properties to various plastic substrates such as PC and ABS, and can achieve good adhesion even when used alone. It also has good adhesion properties to substrates such as paper, wood, and metal, and can be used for thick UV coating.
