These dicyandiamide, boron-based catalysts, and substituted urea catalysts are key components of latent, 1K heat-cured epoxy systems. They control the cure speed and reduce cure temperatures of dicyandiamide cured formulations and help optimize productivity, energy use, and ultimate physical properties.
