2. Features:RU-4128B is a UV resin with medium performance, high reactivity, and high molecular weight for plastic spraying. It does not contain organic tin compounds and its main characteristics are to improve the leveling state, eliminate surface defects such as pitting, pinholes, and orange peel on the coating, and improve the surface cleanliness and other comprehensive properties of the coating. It has excellent adhesion performance to various plastic substrates such as PC and ABS, and can also achieve good adhesion when used alone.
