The present invention relates to a stabilizer composition containing at least one sterically hindered amine (HALS) in which the amino group carries a basicity-reducing substituent, at least one antioxidant containing one or more thioether groups and at least one liquid plasticizer containing carboxylate groups. The invention further relates to a polymer composition containing at least one sterically hindered amine (HALS) in which the amino group carries a basicity-reducing substituent, at least one antioxidant containing one or more thioether groups, at least one liquid plasticizer containing carboxylate groups and at least one silyl-terminated polymer, to the use of the stabilizer composition for stabilizing a silyl-terminated polymer or a sealant, adhesive, gasket, knifing filler or coating composition, especially a sealant, adhesive, gasket, knifing filler or coating composition containing a silyl-terminated polymer, against degradation by heat, light and/or oxygen, to the use of the polymer composition as or in a sealant, adhesive, liquid gasket, knifing filler or coating composition, and to a sealant composition or an adhesive composition, or a gasket composition, or a knifing filler composition or a coating composition comprising the polymer composition.
本发明涉及一种稳定剂组合物,其中至少含有一种氨基带有还原碱性取代基的立体受阻胺(HALS)、至少一种含有一个或多个硫醚基团的抗氧化剂和至少一种含有羧酸基团的液体增塑剂。本发明还涉及一种聚合物组合物,该组合物含有至少一种氨基带有碱性还原取代基的立体受阻胺 (HALS)、至少一种含有一个或多个硫醚基团的抗氧化剂、至少一种含有羧酸基团的液体增塑剂和至少一种硅烷封端聚合物,该稳定剂组合物可用于稳定硅烷封端聚合物或密封剂、粘合剂、垫圈、刀具填料或涂层组合物、稳定剂组合物用于稳定密封剂、粘合剂、垫片、切削填充剂或涂层组合物,特别是含有硅烷基封端聚合物的密封剂、粘合剂、垫片、切削填充剂或涂层组合物,使其不受热、光和/或氧的影响而降解;稳定聚合物组合物作为密封剂、粘合剂、液体垫片、切削填充剂或涂层组合物或在其中使用;稳定包含聚合物组合物的密封剂组合物、粘合剂组合物、垫片组合物、切削填充剂组合物或涂层组合物。
