CA 2567743

The invention provides UV-barrier formulations which result in products which effectively resist the transmission of ultraviolet light therethrough. The invention also provides UV-barrier formulations which result in products with improved resistance to ultraviolet light. In particular, the invention provides UV barrier formulations for polyester resins that have improved resistance to ultraviolet radiation, and significantly reduce ultraviolet light transmission in the resulting resin products. The invention also provides products and manufacturing processes based on the above formulations.

L'invention porte sur des formulations faisant barrière aux UV qui permettent de fabriquer des produits qui résistent efficacement à la transmission de la lumière ultraviolette et qui ont une meilleure résistance à la lumière ultraviolette. L'invention porte notamment sur des formulations de résine de polyester faisant barrière aux UV qui ont une meilleure résistance aux rayonnements ultraviolets et qui réduisent considérablement la transmission de la lumière ultraviolette dans les produits de résine obtenus. Cette invention porte également sur des produits et sur des processus de fabrication basés sur les formulations précitées.
