Selecting the correct curing agent for a two component epoxy system is just as
important as selecting the correct resin. Listed below are many of the curing agents that
can be selected with Epoxies, Etc's... resins. They offer different pot lifes,
viscosities, durometers, and temperature capabilities.
Our Most Popular Curing Agents
- Room Temperature Cure
- Catalyst 190
Hardest and best chemical resistance from a room temperature curing agent.
- Catalyst 150
Water clear, low viscosity and excellent thermal shock resistance.
- Heat Cure
- Catalyst 105
Provides best balance of properties. Outstanding heat and chemical resistance.
- Catalyst 179
Best high temperature resistance.
Technical detailed information on several of our curing agents is listed below.
