Antioxidants and UV Stabilizers for Coatings and Adhesives
SI Group carries a complete portfolio of antioxidants and UV stabilizers for the coatings and adhesives industries, including drop-in equivalents to IRGANOX®, TINUVIN®, and Uvinul®. Primary antioxidants and UV stabilizers are essential for coating and adhesive formulations. Oxygen in paint containers means oxidation and polymerization interact with the end-use product, ultimately causing potential discoloration and loss of mechanical and physical properties of the coating or adhesive.
UV light stabilizers prevent degradation, such as color damage and delamination of coatings and adhesives. The SI group portfolio has two main light stabilizer additives that protect the coating and adhesive formulations. The first is UV absorber additives which absorb any harmful UV radiation and dissipate it as heat. The second is Hindered Amine Light Stabilizers (HALS) which scavenge radicals and are only activated when light is exposed to the coating or adhesive.
