Description

L-1251 is a hydroxyl-containing acrylic copolymer. At room temperature, it can be combined with a non-yellowing isocyanate to form a two-component system with excellent application performance, good silver pigment orientation, and outstanding compatibility. It is highly suitable for two-component silver or pearlescent coatings and also provides excellent physical and chemical properties as well as pigment dispersion; it can additionally be used for solid-color coatings. Notably, it exhibits excellent RCA resistance, up to around 200 cycles, and shows good adhesion to substrates such as ABS, PC, glass fiber–reinforced PC, PMMA, fiberglass, and various metals.
