Properties: White crystal, Soluble in acetone, ethyl acetate, isopropyl alcohol, hot methanol and other organic solvents, insoluble in water. In acid decomposition, stable in alkaline, sensitive to light. Low toxicity.
Application: Used for light initiator, preparation light curing adhesives, maximum absorption wavelength of 337 nm, suitable for unsaturated polyester/styrene, acrylate and siloxane etc.Thermal stability is very good, has the high quenching resistance and light initiator activity, but yellow degeneration is more serious.
Storage Notes: Sealed stored in cold, dry, good ventilated place, avoid direct sunlight.
