SpeedCure 97 by Lambson (Sartomer) is a 2-methyl-1-[4-(methylthio)phenyl]2-morpholinopropan-1-one. Acts as a Type I photoinitiator. It initiates UV photo-polymerization typically with unsaturated monomers and polymers such as acrylates/methacrylates or vinyl polymers. Exhibits good reactivity and offers good surface cure. Addition of thioxanthone sensitiser increases cure speed. It is a white colored powder. Particularly suitable for pigmented systems operating in the UV absorption 250 – 350 nm wavelength. SpeedCure 97 is used for very high speeds in clear coatings (0.1-1%), offset inks (4-6%), screen inks (2-4%), overprint varnishes, wood lacquers, printing inks and silicone based coatings.
