Abstract | The invention is directed to stabilizer compositions comprising at least one oxalanilide UV absorber and/or at least one (2-hydroxyphenyl)-s-triazine UV absorber, and at least one oligomeric hindered amine light stabilizer (HALS), optionally further comprising at least one phenolic antioxidant, at least one liquid diluent and/or further components. Said stabilizer compositions are preferably used in sealants or adhesives based on silyl-modified polymers (SMP). The invention also deals with a polymer composition based on silyl-modified polymers (SMP) comprising the new stabilizer combination of oxalanilide UV absorber and/or (2-hydroxyphenyl)-s-triazine UV absorber, and oligomeric hindered amine light stabilizer (HALS), optionally further comprising phenolic antioxidant and liquid diluent and/or further components.
La présente invention concerne des compositions d'agent stabilisant comprenant au moins un agent absorbant les UV oxalanilide et/ou au moins un agent absorbant les UV (2-hydroxyphényl)-s-triazine, et au moins un agent oligomère stabilisant la lumière type amine bloquée (HALS), comprenant en outre éventuellement au moins un antioxydant phénolique, au moins un diluant liquide et/ou des constituants supplémentaires. Lesdites compositions d'agent stabilisant sont préférablement utilisées dans des agents d'étanchéité ou des adhésifs à base de polymères modifiés avec un groupe silyle (SMP). L'invention concerne également une composition polymère à base de polymères modifiés avec un groupe silyle (SMP) comprenant la nouvelle combinaison d'agents stabilisants d'agent absorbant les UV oxalanilide et/ou d'agent absorbant les UV (2-hydroxyphényl)-s-triazine, et d'agent oligomère stabilisant la lumière type amine bloquée (HALS), comprenant en outre éventuellement un agent antioxydant phénolique et un diluant liquide et/ou des constituants supplémentaires. |
