Applications:

It is widely used in the applications of MTHPA, and specially as curing agent for the products of outside of house, such as light emitting diode (LED), igniter, especial capacitor, transformer, electric, motor, sport & entertainment material etc. which the resistance to UV and dampness is required.

 

Features:

1.      It is an acid anhydride type curing agent with high performance. It has the typical performances as MTHPA: high purity, light color, low viscosity, low volatility, low toxicity, low heating loss, stable performances, long use life, low freezing point, and can be stored for a long time under room temperature.

2.      It has more excellent performances than that of MTHPA: colorless, transparent, basically unchanged color after being added accelerant.

3.      The appearance of final products is white;, good resistance to heat, especially under the temperature lower than 150C, excellent mechanical and electric properties, excellent weatherability, not be affected by light and heat, good moisture resistance, high reaction activity, fast solidifying speed and short gelation time.
