Description

L-6608 high viscosity 6-functional UV polyurethane resin is recommended for hard high performance light curing applications such as coatings, inks, UV vacuum plating, UV screen printing inks, UV offset printing inks, etc. It has high crosslinking density, hard but not brittle paint film, excellent surface drying, and only requires very low energy to dry on thin coatings. When diluted with 30% of active diluents, it still has excellent surface drying properties, high leveling gloss, good wetting and leveling properties, and weather resistance.

Storage

To prevent the product from being highly active and causing a polymerizing reaction, please seal it and store it away from heat sources and sunlight. The recommended storage temperature is no higher than 30°C. Unused products must be sealed and stored in a timely manner. Do not store them in the open. At 25°C and well ventilated, the safe storage period is 6 months. 20KG/25KG/200KG/barrel

Tips: L-6608 is a high viscosity 6-functional resin. After being diluted with active diluent, its surface dry performance is still excellent.
