The current research is devoted to the research of potential catalysts for the two-component silyl-terminated prepolymer/epoxy resin system. The catalyst system must catalyze the prepolymer of the opposite component while not curing the prepolymer in the component in which the catalyst is located. Mechanical and rheological characterization of the adhesive was performed. The results of the investigation showed that certain alternative catalyst systems, which are less toxic, may be used instead of traditional catalysts for individual systems. Two-component systems, obtained by using these catalysts systems, cure in an acceptable time scale and demonstrate relatively high tensile strength and deformation values.
当前的研究致力于双组分硅烷基封端预聚物/环氧树脂体系潜在催化剂的研究。该催化剂体系必须催化相反组分的预聚物，同时又不会使催化剂所在组分中的预聚物固化。对粘合剂进行了力学和流变学表征。研究结果表明，某些毒性较小的替代催化剂体系可用于替代个别体系中的传统催化剂。使用这些催化剂体系获得的双组分体系在可接受的时间范围内固化，并表现出相对较高的拉伸强度和变形值。
