Product: 2-Hydroxy-4-Octyloxy Benzophenone
Synonyms: UV-531; Benzophenone-12
CAS NO: 1843-05-6
Molecular formula: C21H26O3
Structure formula:
Properties:
Yellowish crystal or powder. Freely soluble in benzene, n-hexane, acetone, slightly soluble in ethanol, very slightly soluble in ethane dichloride.
Application:
This product is a light stabilizer with good performance, capable of absorbing the UV radiation of 240-340 nm wavelength with the characteristics of light color, nontoxic, good compatibility, small mobility, easy processing etc. It can protect the polymer to its maximum extent, helps to reduce the color. It can also delay the yellowing and obstacle the loss of its physical function. It is widely applied to PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability effect on drying phenol aldehyde, alcoholic acid varnish, polyurethane, acrylate, epoxylite etc. Its dosage is 0.1%-0.5%.
