Description

L-1200Ais an OH group-containing acrylic copolymer. When paired with non-yellowing polyisocyanate 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 two-liquid silver paint. , pearlescent powder paint, which has excellent physical and chemical properties and pigment dispersion, and can also be made into solid color paint.

Storage, shelf time and Packing

To prevent the product from polymerization and gelling, please keep it sealed and away from heat and light. Recommended storage temperature is not higher than 30°C. Unused products must be sealed and stored in a timely manner and cannot be stored in the open. Safe storage time is 6 months at room temperature( 25ºC) and under ventilation. 20KG/25KG/190KG/barrel


Tips: L-1200A is mainly used as a primer, and its adhesion to various metal substrates such as aluminum and stainless steel is much better than L-1201.
