Light stabilizers are a group of additives that have been developed to minimise or prevent the damage to plastics caused by exposure to the environmental parameters of light, heat and air. Sinoxe light stabilizing additives, suitable for water and solventborne coatings, adhesives and sealants, filter harmful UV light and act as free radical scavengers to maintain their appearance, as well as their chemical and physical properties.
Stabilizers for polymers are used singly or in combinations to prevent the oxidation, chain fission, uncontrolled recombinations and cross-linking reactions that are caused by photo-oxidation of polymers. Polymers become weathered by the direct or indirect impact of heat and ultraviolet light. Sinoxe hindered amine light stabilizers (HALS) are extremely effective in polyolefins and polyurethane
