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 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.
