Irgacure 651Usage

1. Irgacure 651 is a photoinitiator that is widely used in UV curing systems. Strong absorption in inks, varnishes and other systems. It is mainly used as a light curing agent for UV curing systems and is used in ink, paper and metal paints. Store in a sealed package, protected from light and heat.

2. It is widely used in the polymerization of acrylate and monomer and the polymerization and crosslinking of unsaturated polyester. It has been applied in coatings and adhesives.

For example

The combination of photoinitiator 819 and IRGACURE 651 is particularly suitable for curing polyester/styrene resin systems, such as glass fiber reinforced materials.
