| Ciba Specialty Chemicals (China) Limited Additives Irganox B900 Irganox B900 is an antioxidant and high-temperature processing of both long-lasting antioxidant effect of high-performance composite antioxidant, can be used for a variety of polymers and synthetic materials such as: plastics, elastomers, coating resins, in order to protect these materials do not occur thermo-oxidative degradation. Irganox B900 tasteless, with good light and excellent color stability, prison sex, with most of the polymers have good compatibility, low volatility and high extraction resistance characteristics. Irganox B900 can be mixed with other additives, such as: light stabilizer and antistatic agents. Chemical composition: Sub-Tris (2,4 - di-tert-D-phenyl) ester hindered phenol (3,5 - 2-butyl -4 - hydroxy - 18 alkyl-phenyl propionate) Physical properties: Appearance: white crystalline powder Melting point: 50 ℃ -182 ℃ Density: 1.02-1.03g/cm3 Solubility: (reference data) (20 ℃,% W / W) benzene, acetone, an acetate 43 Xylene 36 chloroform 45 cyclohexane 20 Ethyl 5 Water <0.01 Irganox B900 in the coatings industry in the application: application of polyurethane, polyester and alkyd resins in the synthesis and powder coating production can reduce the resin color to enhance anti-yellowing properties. Class Project to add volume (resin solid content)% Add Method color polyurethane prepolymer (TDI, MDI) 0.1-0.5 1 file (water white) mixed in with TDI or MDI solution was added dropwise at 80 ℃ below with OH component polyester resin mixed ester 0.3 1-2 files and to participate in esterification of alkyd resins 0.1-0.3 2-4 files with the oil mixture of alcohol alcohol solution or alcohol solution to join or post-esterification time (including fatty acids) by adding 0.3-0.5 Powder Coatings added to the resin storage and safe operation: Irganox B900 storage should be consistent with good industrial demand, detailed information, please refer to Safety Data Sheet. |
