- Curing Properties: MTHPA is an effective curing agent for epoxy resins, providing excellent heat and chemical resistance. It helps convert the liquid epoxy resin into a solid, durable, and thermoset material.
- Low Viscosity: MTHPA typically has lower viscosity compared to other curing agents, making it easier to handle and mix with epoxy resins, improving processing and application characteristics.
- Thermal Stability: The cured epoxy with MTHPA exhibits good thermal stability, making it suitable for applications where temperature resistance is essential.
- Electrical Properties: The cured epoxy resins with MTHPA as the curing agent show good electrical properties.
Typical applications include epoxy coatings curing agent systems, potting compound curing agent formulations, electrical insulation casting and industrial epoxy laminates. This grade is supplied as a solvent-free epoxy curing agent with high purity, offering excellent adhesion, long working time, and long pot life profile. It complies with RoHS and REACH standards and is suitable for solvent-free potting systems, chemical resistant applications, and general industrial epoxy curing services.
