Omnirad 2959

Technical Datasheet | Supplied by IGM Resins
Omnirad 2959 (Former Irgacure 2959) by IGM Resins is a non-yellowing radical photoinitiator for the UV curing of systems comprising of unsaturated monomers and prepolymers. It is especially suited where low odor is required and for use in water-borne systems based on acrylate or unsaturated polyester resins. The active hydroxy group can be reacted with suitable functionalized unsaturated resins. May be used in UV curable formulations on substrates like wood, metal, plastic and paper. The hydroxy functional group enhances the compatibility in water-borne coating formulations. Demonstrates low volatility and low odor as a pure substance as well as in cured films. Potential to react the hydroxy functional group to form a grafted photoinitiator onto a resin backbone, resulting in system with minimum extractability of the photoinitiator. Recommended when high temperatures and air circulation are required for water evaporation prior to UV curing of the coating and for formulations where minimum residual odor is required. Recommended usage level of Omnirad 2959 is 2.0-5.0% on resin weight.
