Ethyl 4-[[(methylphenylamino)methylene]ami ethyl 4-[(N-methylanilino)methylideneamino] benzoate CAS NO.57834-33-0

The effective UV absorptivity is in the range of 240-350nm. The maximum absorption peak is 308nm. It can almost completely absorb ultraviolet radiation in the 300-330nm region. Due to radiation in this wave range, polyurethane degrades easily. It has excellent light stability for polyurethane products such as soft bubble, hard bubble, elastomer, artificial leather, adhesive and Coating. Prevent aging, improve color stability, extend product life.
