CAS NO.

PROPERTY

• Low viscosity and low volatility, easy to handle at room temperature.
• Medium-temperature curing imidazole catalyst, with a curing temperature range of 60–150°C.
• Excellent compatibility with epoxy resins and effective at low addition levels.
• The cured material offers good heat resistance, mechanical strength, and electrical insulation properties.
• Stable during long-term storage; if crystallization occurs, it can be restored by heating without affecting performance.

APPLICATIONS

• Epoxy resin curing agent / accelerator: used in potting, casting, laminating, adhesives, insulating varnishes, and powder coatings.
• Synthetic intermediate: used in pharmaceuticals, pesticides, dyes, and organic synthesis catalysts.
• Electronic packaging: used for insulation and protection of semiconductors, coils, and PCB boards.

INDEX

CURING CONDITIONS

When used as an epoxy curing agent, the curing conditions are 60°C for 2 hours, 70°C for 4 hours, or 70°C for 1 hour followed by 150°C for 4 hours. The heat distortion temperature of the cured material is 150–170°C.

PACKAGING AND STORAGE
