Darocur 4265 Blend of 2,4,6-trimethylbenzoyl-diphenyl-phosphineoxide and 2-hydroxy-2-methyl-1-phenyl-propan-1-one Ciba Photo Initiators >> Synergists Acrylics/ Acrylates Polyesters ADHESIVE >> Radiation Curing (UV/EB) ADHESIVE >> Water-based DAROCUR 4265 is a highly efficient liquid curing agent which is used to initiate radical photopolymerisation of unsaturated resins such as those based on a prepolymer - e.g. acrylates - in combination with mono- or multifunctional monomers as reactive thinners. 50 % 2,4,6-Trimethylbenzoyl-diphenyl-phosphineoxide - 50 % 2-Hydroxy-2-methyl-1-phenyl-propan-1-one (DAROCUR® 1173) DAROCUR 4265 may be used after adequate testing for UV curable transparent and pigmented wood finishes as well as white UV inks. DAROCUR 4265 offers good solubility in common UV reactive systems, e.g. systems based on acrylates or unsaturated polyesters. Due to its liquid state, DAROCUR 4265 can also be incorporated in waterborne systems. Blend of 2,4,6-trimethylbenzoyl-diphenyl-phosphineoxide and hydroxy-2-methyl-1-phenyl-propan-1-one. Used as a curing agent to initiate radical photopolymerisation of unsaturated resins in combination with mono- or multifunctional monomers as reactive thinners. May be used for UV curable applications. Offers good solubility in common UV reactive systems. Can be incorporated in waterborne systems. Use level : 1-5%.
