Characteristics: Curekind  445 white to light-grey powder or crystals, density:1.14, purity melting point:101℃. Soluble in rubber and all kinds of organic solvent, slightly soluble in water and alcohol, thermal decomposition temperature: 280 ℃; Volatile: high molecular weight and low volatile
Application: 445 is heat resistant (slightly staining) antioxidant. It is a slightly staining & discoloring antioxidant being stable at high temperature, is used for protection against heat and oxidative degradations in NR and synthetic rubbers including BR, SBR, NBR, CR and EPDM covering uses in beltings, hoses, seals, gaskets and other
automotive/industrial rubber products. In combination with synergistic antioxidants it provides an extremely
effective antioxidant system for EPDM and NBR compounds for high temperature applications. Often used as
aqueous dispersions in latex compounds (SBR, Carboxylated SBR and NR) for improving resistance to heat and embrittlement during aging with as little 0.5 phr in the compound. Typical dosages in rubber vary from 1 to 3 phr depending on the application parts. In the compound dosage of 0.5-1% can substitute when 1.5-2% of age-resistant D, BHT, RD,MB, etc.
Safety and Toxic: Refer to the MSDS.
Storage: Store in a cool, dry & well-ventilated place, local exhaust recommended. Keep container closed when not in use.
