Does adding too much epoxy resin curing agent have an impact?
Regardless of the type of polyester resin curing agent, precise matching is required, and epoxy resin is no exception. Returning to the main topic, what will be the impact of adding too much epoxy resin curing agent?
Firstly, under the same environment, the curing speed of resin adhesive will become faster, and a small amount of curing agent color will remain in the cured parts, such as light yellow T31 curing agent. At the same time, the final product will have poorer toughness, relatively brittle, and slightly decreased strength.
Secondly, if the curing dosage ratio exceeds too much, the epoxy resin adhesive may remain stuck or unevenly cured.
So, if you need to increase the curing speed of epoxy resin, you should improve the curing conditions, rather than adding more epoxy resin curing agents to solve the problem.
