More Information
Summary: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.
