产品简介
R-gen® 7W是专为水性和有色UV体系固化而开发的高性能光引发剂。
产品详情
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.
