- Compatible with a wide variety of systems
- Low migration effects
- FDA cleared for use in adhesives, rubber articles, polyolefins, and polyacetals
Guidelines for Use
Recommended concentrations for use in plastics and adhesives range from 0.05 to 0.5%. Combinations of BNX 2246 with other antioxidants such as phosphites and thioethers often show synergistic performance. BNX 2246 is also suitable for use in combination with light stabilizers, including hindered amine light stabilizers (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. Please contact Mayzo for specific recommendations.
This product may be stored up to two years in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool, dry place.
Please consult the Safety Data Sheet (SDS) prior to handling or using this product.
BNX 2246 is cleared for use in adhesives under 21 CFR §175.105, rubber articles intended for repeat use under 21 CFR §177.2600, and in olefin polymers and polyoxymethylene homo- and copolymers under 21 CFR §178.2010.
