    • Two-part adhesive compositions are described. The two-part adhesives have a first part and a second part, said composition comprising at least one aromatic epoxy resin in the first part; at least one amine curing agent in the second part; and at least one ester in at least one of the first and/or second part. The ester corresponds to the general formula R2—CO—OR1; wherein R1 is an organic moiety comprising at least one of (i) at least one epoxy group or (ii) at least one acryl group and R2 is a branched alkyl group. The structural adhesive may be used to form bonded joints between adherents having clean surfaces, as well as those having surfaces contaminated with hydrocarbon-containing materials, such as oils, processing aids and lubricating agents.
    • 描述两部分粘合剂组合物。 两部分粘合剂具有第一部分和第二部分,所述组合物在第一部分中包含至少一种芳族环氧树脂; 第二部分中的至少一种胺固化剂; 和在第一和/或第二部分中的至少一个中的至少一个酯。 该酯对应于通式R2-CO-OR1; 其中R1是包含(i)至少一个环氧基团或(ii)至少一个丙烯酰基团中的至少一个的有机部分,R 2是支链烷基。 结构粘合剂可以用于在具有干净表面的粘合剂之间形成粘合接头,以及具有被含烃材料(例如油,加工助剂和润滑剂)污染的表面的结合粘合剂。
