Firstcure ITX Isopropylthioxanthone (2 & 4-isomer mixture) 5495-84-1 Albemarle Photoinitiator >> Amine Acrylic/Acrylate Resins Polyester >> Unsaturated Coatings >> UV / Radiation Curing Inks >> UV / Radiation-curable INKS FIRSTCURE ITX photoinitiator is a yellow crystalline powder compatible with unsaturated polyesters, acrylate monomers and oligomers used in UV-curable systems. It is an effective photoinitiator for clear or pigmented UV-curable inks, adhesives, coating and photoresists. It is typically used with an amine synergist such as [ethyl-p-(dimethyl amino benzoate (EDAB)] or octyl-p-dimethyl amino benzoate (ODAB). FIRSTCURE ITX photoinitiator also acts as a sensitizer when used with cationic photoinitiators.. Photoinitiator, yellow crystalline powder compatible with unsaturated polyesters, acrylate monomers and oligomers. It is used in UV-curable acrylate-based coatings, adhesives and inks.
