BNX® 3052

1 of 27 products in this brand
BNX 3052 (61167-58-6)is a multifunctional antioxidant for the stabilization of adhesives, elastomers, and plastics. Unlike conventional phenolic antioxidants, BNX 3052 is effective to scavenge alkyl (carbon-centered) radicals. The product is particularly active under demanding processing conditions (high temperature, high shear) and under anaerobic conditions.

Functions: Antioxidant

Applications

BNX 3052 is particularly useful for the stabilization of adhesives and elastomers derived from butadiene and other dienes, for example polybutadiene and copolymers of polybutadiene and other monomers. The product is also effective in the stabilization of HIPS, ABS, SBS, SBR, NR, EPDM, and hydrocarbon resins.

Guidelines for Use

The recommended loading levels in adhesives, elastomers, and plastics range between 0.05 and 0.5%. Best results in terms of processing and thermal oxidative stability are generally obtained by combining BNX 3052 with conventional phenolic antioxidants and secondary antioxidants (phosphites, thiosynergists, and the like). BNX 3052 can also be used in combination with light stabilizers such as HALS, UV absorbers, and benzoates. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use
