Silcolease® UV CATA 261 is a cationic photoinitiator designed for use with UV curable epoxy resins. It has been specially formulated for ease of use and excellent compatibility with a wide range of epoxy resins. The UV CATA 261 contains (tolylcumyl) iodonium tetrakis (pentafluorophenyl) borate, which is non-hydrolysable, non-hygroscopic, and has a higher thermal stability compared to other photoinitiators on the market.
• Low viscosity
• Liquid pourable
Typically used at concentrations of 1-3% w/w in the UV resin formulation.
