What is Irgacure 127?
Irgacure 127 (CAS 474510-57-1), also known as Bis(4-(2-hydroxy-2-methylpropionyl)phenyl)methane, is an alpha-hydroxy ketone photoinitiator for UV-curable systems.
Where is Irgacure 127 used?
- Coatings for wood, plastic and metal: fast surface cure with minimal yellowing
- Adhesives and sealants: controlled cure depth and bond strength in structural applications
- Pressure-sensitive applications
- Printing inks, including offset, flexo and screen: cure performance in pigmented and clear systems
- Photopolymer formulations for electronics and optical applications
- Upon UV exposure it generates free radicals that trigger polymerization and crosslinking.
Good to know: Low volatility and high molecular weight support compliance; specified where low extractable content is a strict regulatory requirement.
Commercial specifications
- Purity typically at or above 98%
- Packaging from kilogram quantities for laboratory and development use to bulk quantities for commercial formulation
