LOTNOX 565(ANTIOXIDANT 565) (CAS:991-84-4)

LOTNOX 565(ANTIOXIDANT 565)

CAS NO.[991-84-4]  2,6-Di-tert-butyl-4-(4,6-bis(octylthio)-1,3,5-triazin-2-ylamino)phenol

Lotnox 565 is a high molecular weight, non-staining, multifunctional phenolic antioxidant primarily used as a post-polymerization process stabilizer for unsaturated elastomers.

C₃₃H₅₆N₄OS₂

Features & benefits

Lotnox 565 is highly effective at low concentrations, matching the performance of other stabilizers at higher levels. It is non-staining and due to its low volatility, Lotnox 565 is not lost during polymer processing, drying or storage. Lotnox 565 can be used in a wide variety of applications. In unsaturated elastomers, Lotnox 565 prevents gel formation, maintains excellent polymer color, and prevents changes to molecular weight (e. g. Mooney viscosity).

Applications

Lotnox 565 is a highly effective antioxidant for a variety of elastomers including polybutadiene (BR), polyisoprene (IR), emulsion styrene butadiene (SBR), nitrile rubber (NBR), carboxylated SBR Latex (XSBR), and styrenic block copolymers such as SBS and SIS. Lotnox 565 is also used in adhesives (hot melt, solvent-based), natural and synthetic tackifier resins, EPDM, ABS, high impact polystyrene, polyamides, and polyolefins.
