Beschreibung
Zusammenfassung:	Disclosed is a moisture curable adhesive composition comprising at least one silane-modified polymer, a filler comprising a surface modified fumed silica and one of a surface modified cristobalite and a silica; and optionally, at least one of an amino silane adhesion promotor, an organotin catalyst, a dehydration shelf life enhancer, a light stabilizer, titanium dioxide, a rheology modifier, and mixtures thereof. The adhesive composition finds special use in bonding metal substrates to each other with significantly higher bond strength than that provided by silane-modified polymer adhesives alone. 本发明公开了一种可潮气固化的粘合剂组合物，其包含：至少一种硅烷改性的聚合物；包含表面改性的热解法二氧化硅、以及表面改性的方石英和二氧化硅之一的填料；和任选存在的以下物质中的至少一种：氨基硅烷粘合促进剂、有机锡催化剂、脱水储存期限增强剂、光稳定剂、二氧化钛、流变改性剂及它们的混合物。该粘合剂组合物特别适用于将金属基材以比硅烷改性的聚合物粘合剂单独所提供的粘合强度显著地高的粘合强度彼此粘合。
