Harwick Standard Distribution Corp.: STANLIGHT UV Absorbers: UV Absorbers work by absorbing light energy before it has a chance to begin degradation, and changing it into harmless heat energy, which is dissipated throughout the substrate. UV absorbers are based on substituted hydroxybenzotriazoles, which are less prone to discoloration than absorbers based on hydroxybenzophenones.
Stanlight P UV Absorber: Stanlight P is economical but also volatile and less soluble in most solvents. Stanlight P is recommended especially for ambient cure systems, and for some resins in thick section. It is not recommended for two component urethane systems because of the possibility of the hydroxyl group on the stabilizer reacting with the isocyanate. (A similar situation is true with most HALS). Stanlight P can also be used in conjunction with Stanlight 770 to provide optimum protection to polyolefins in thick section, especially when pigmented with light-sensitive colorants. In addition, most coatings systems benefit from a combination of UV absorber and HALS.
Stanlight 770 UV Light Stabilizer: Stanlight 770 general purpose HALS recommended for a variety of materials. Especially recommended for polypropylene thick section, also polypropylene tape. Stanlight 770 can also be used in conjunction with Stanlight P to provide optimum protection to polyolefins in thick section, especially when pigmented with light-sensitive colorants. In addition, most coatings systems benefit from a combination of UV absorber and HALS. Stanlight 770 UV Light Stabilizer is a hindered amine light stabilizer. It is highly effective in the most demanding UV light stabilization applications including use in polypropylene, high-density polyethylene, EPDM, poly and all styrenic polymers. Stanlight 770 can be combined with UV absorbers to optimize a polymer’s UV light stabilization properties. It has no effect on the polymer’s color, as there is no absorption in the visual spectrum. Stanlight 770 is highly effective in applications exhibiting high surface areas or having large cross sections.
