Description

L-1250 is an OH group-containing acrylic copolymer. When combined with non-yellowing isocyanate at room temperature, it can be made into a two-liquid system with good construction performance, good arrangement of silver powder, and excellent matching performance. It is very suitable for making two-liquid silver powder. Paint, pearlescent powder paint, has excellent physical and chemical properties and pigment dispersion, and can also be used to make solid color paint. It has good adhesion to substrates such as ABS, PC, PC fiber reinforced plastic, PMMA, fiberglass, and various metals.
