Extremely rapid ambient curing of polyepoxide resins and mixtures of polyepoxide resins and polyacrylate esters is achieved by use of a curing system composed of at least one polymercaptan and at least one catalytic co-curing agent which is the condensation product of:
(a) aliphatic amine or substituted aliphatic amine containing at least one primary aliphatic amine group where the aliphatic moiety is ethylene or greater with
(b) at least one amino acid, its corresponding lactam or other amide forming derivative.
Optionally, known Lewis Base catalysts for the epoxy/ mercaptan reaction, such as tertiary amines, may also be used.
通过使用由至少一种聚合物硫醇和至少一种催化助固化剂组成的固化体系,可实现聚环氧树脂以及聚环氧树脂和聚丙烯酸酯混合物的极速常温固化。 催化助固化剂是下列物质的缩合产物:(a) 脂肪族胺或含有至少一个伯脂肪族胺基团的取代脂肪族胺,其中脂肪族分子为乙烯或更大的乙烯基;(b) 至少一种氨基酸、其相应的内酰胺或其他酰胺形成衍生物。 也可选择使用已知的环氧/硫醇反应路易斯碱催化剂,如叔胺。
