The full service we are offering is specifically designed to meet your business needs and projects.

Curing Performance

MTHPA has low viscosity and long pot life, making it easy to use. It cures slowly and consistently, giving time for proper adhesion to different substrates.

Mechanical Strength

MTHPA-cured epoxy resins are durable and reliable, ideal for heavy-duty work and high weight capacity structures, favored by multiple industries.

Thermal Stability

Cured epoxy resin with MTHPA hardener is thermally stable, suitable for high-temperature applications.

Chemical Resistance

MTHPA-cured epoxy resins resist many chemicals, making them useful in chemical-heavy environments.

Electrical Properties

MTHPA-cured epoxy resins have excellent electrical insulation, ideal for electronics and electrical industries.

Versatility

MTHPA works with various epoxy formulas – adhesives, coatings, composites, encapsulants, and electrical laminates.
