  • Benzotriazole/HALS molecular combinations and compositions stabilized therewith
    Patent number: 7419513
    Abstract: Compounds which have a benzotriazole and a hindered amine moiety in the same molecule are typified by the formula A wherein at least one of G2, R1 or R2 contains a hindered amine moiety are extremely effective light stabilizers having both the UV absorbing activity of a benzotriazole and the light stabilizing efficacy of a hindered amine in the same molecule. These compounds are effective stabilizers for thermoset resin compositions, thermoplastic resin compositions, for photographic applications, for pigmented or dyed polypropylene, polyamide or polyester fibers, and for white, dyed, dipped, unscented and/or scented candle wax against discoloration and fading when incorporated therein alone or in combination with an antioxidant.
    Type: Grant

  • Weatherable powder coating compositions
    Patent number: 5097006
    Abstract: Carboxyl-terminated and hydroxyl-terminated aliphatic polyester compositions derived from 1,4-cyclohexane-dicarboxylic acid, and a glycol component comprising primarily of cycloaliphatic diols and modifying aliphatic glycols, said polyesters being optionally stabilized by the presence of ultraviolet light absorbing compounds and/or hindered amine light stabilizers and being used in powder coating formulations to provide improved weatherability thereto.
