Irganox 1520 4,6-bis (octylthiomethyl)-o-cresol 110553-27-0 Ciba Antioxidants >> Phenolic Rubber - Elastomer (Chloroprene, Butyl …) SEALANT ADHESIVE IRGANOX 1520 L is a multifunctional phenolic antioxidant for organic substrates such as elastomers, plastics, adhesives, sealants, oils and lubricants. It effectively protects these substrates against thermo-oxidative degradation during processing and long-term heat aging. IRGANOX 1520 L is non staining, non discoloring, low in volatility, and stable to light and heat. IRGANOX 1520 L is specially recommended for emulsion and solution polymerized elastomers, such as BR, SBR, NBR, SBS and others. IRGANOX 1520 L is an effective thermo-oxidative stabilizer in a wide range of solution polymerized, emulsion polymerized and thermoplastics elastomers including BR, SBR, NBR, IR, SBS, and SIS as well as natural rubber. The antioxidant is effective both as a raw elastomer ans compound stabilizer. It as also effective in various adhesive and sealant applications. IRGANOX 1520 L is not recommended for odor sensitive hor melt adhesives or their raw materials. IRGANOX 1520 L is unique in its ability to provide both processing and long-term heat aging stability used alone, at low levels and without costabilizers. Where necessary, IRGANOX 1520 L can be used with other additives such as secondary antioxidants, light stabilizers and other functional stabilizers. The effectiveness of theses products in a wide range of elastomers coupled with extensive food contac approvals makes IRGANOX 1520 L an excellent choice where consolidation of antioxidant systems is desirable. In addition, the liquid, low viscosity nature of IRGANOX 1520 L makes bulk delivery and storage very convenient. Non staining, non discoloring, multifunctional phenolic antioxidant. Used in organic substrates such as adhesives and sealants. Specially recommended for emulsion and solution polymerised elastomers such as BR, SBR, NBR SBS, and others. Protects against thermo-oxidative degradation during processing and long-term heat aging. Possesses low volatility, low viscosity and high stability to light and heat.
