Product Data Sheet R-gen® 7W 1. Introduction R-gen® 7W is a photoinitiator designed specially for water-borne and pigmented UV system. Its photospeed is as fast as Chivacure® 107, a commonly used photoinitiator for pigmented UV systems, because their structures are resemble to each other except the two hydroxy tails in R-gen® 7W. These two hydroxy tails boosts R-gen 7W®'s hydrophilicity and allowed it to suspend in water. 2. Properties Chemical name: 1-(4-(2-hydroxyethylthio)phenyl)-2-(N-(2-hydroxyethyl)-N-methylamino)-2-methylpropan-1-one CAS no. : 1221233-50-6 Molecular formula : C15H23NO3S Molecular weight : 297.41 3. Physical data Appearance : White powder Odor : Faint Boiling point : > 300°C (572 °F) Melting point : 112-114 °C 4. Specification Appearance : White crystalline powder Assay : 98% min. Melting point : 108 °C min. Volatiles : 0.5% max. Transmittance : 92% min. @425 nm 95% min. @500 nm 6. Solubility (g in 100 ml solvent @20 °C) Toluene : 2.5 Methanol : 15 Butyl acetate : 5 MEK : 15 TMPTA : 10 Water : Nil 7. Application R-gen® 7W is recommended to be dissolved in alcoholic solvents prior to mixing. Due to its strong absorption (ε= 17,300 at 257 nm), R-gen® 7W is very efficient for both clear and pigmented systems; 0.5% of R-gen® 7W is recommended for clear systems and 3-6% is suggested for pigmented systems. R-gen® 7W is ideal for water-borne inject, water-borne solder-mask, and water-borne wood lacquer. 8. Packaging 20kg net/carton box
