B-6263 Special Functional Acrylate

B-6263 is a four-functional polyurethane acrylate with hydroxyl groups. It has fast curing speed, high film fullness and excellent toughness. It can effectively eliminate pinholes and bubbles in the coating and improve hiding power. Excellent boiling resistance. At the same time, the self-contained hydroxyl group, with the cooperation of -NCO, can effectively cure uneven light-receiving locations during UV curing of special-shaped parts. It has good adhesion to ABS and PU primers. A small amount of color addition curing can be done by adjusting the formula.
