Usage

Irgacure 651 is a new type of UV photosensitizer with excellent performance. It produces highly reactive methyl radicals under UV light in amounts from 0.5% to 5%, as well as other benzoin ethers. The photosensitizer has the advantages of high light-initiating efficiency and hiding stability. Irgacure 651 is widely used in the polymerization of unsaturated monomers such as acrylic acid vinegar, methacrylic acid, acrylonitrile, acrylamide, styrene, maleic acid, fumaric acid and mixtures thereof, as well as unsaturated monomers and polyvinyl alcohol. Polymerization, polymerization and crosslinking of polystyrene. Cool oligomer. Therefore, as an initiator, it has broad application prospects in the manufacture of paints, coatings, inks, adhesives and resins.
