UV Stabilizers

Mayzo provides a variety of hindered amine light stabilizers (HALS), which are used to protect adhesives, plastics, coatings, and elastomers from the damaging effects of outdoor weathering that result from exposure to ultraviolet light. These additives function by interrupting the chemical process of photooxidation through reaction with free radical and peroxide intermediates. Combinations of HALS with other kinds of light stabilizers (especially UV absorbers) are often used in order to attain the best resistance to weathering.

BLS 1622
   Solid, high molecular weight HALS especially useful in polyolefins (film,
     tape, fiber, thick-section), ethylene-vinyl acetate copolymers, polyamides,
     polyacetal, polyurethanes, and powder coatings
   Excellent resistance to migration and extraction
   Less basic than other HALS, minimizing interaction with other formulation
     components such as pigments (especially carbon black) and antioxidants
   FDA-cleared* for use in olefin polymers and ethylene vinyl acetate
     copolymers in food contact applications

BLS 292
   Liquid HALS for general purpose use in coatings, adhesives, polyurethanes,
     flexible PVC and in other applications for which a liquid product form
     is preferred

BLS 1770
   Solid HALS for general purpose use in polypropylene (thick-section), TPO,
     styrenic polymers, polyamides, polyacetal, adhesives, and powder coatings
   FDA-cleared* for use in adhesives and pressure-sensitive adhesives for
     food contact applications

BLS 1944
   Solid, high molecular weight HALS especially useful in polyolefins (film,
     tape, fiber, thick-section), TPO, ethylene vinyl acetate copolymers, polyamides,
     rigid PVC, and powder coatings
   Increases the thermal oxidative stability of polyolefins subjected to end
     use at elevated temperatures
   Excellent resistance to migration and extraction
   FDA-cleared* for use in polyethylene and polypropylene in food contact
     applications
