Esacure 1001 M
IGM Resins USA Inc. · Esacure
Esacure 1001 M is a difunctional Type II photoinitiator of the ketosulphone class, used to initiate radical polymerization of unsaturated oligomers like acrylates after UV exposure. It is particularly suitable for pigmented systems and applications requiring low migration and low extraction values, such as food packaging. The product appears as an off-white to pale pink powder, soluble in most common organic solvents.
- Low migration
- Suitable for UV applications
- Compatible with pigments
