Basic Chemical Structure

TMPDE product is a compound of Trimethylolpropane Monoallyl Ether, Diallyl Ether, Triallyl Ether with different proportion.

Chemical Performance                                                                 

TMPDE products perform very stably under usual temperature and humidity, possessing typical character of ether and alcohol functional group. Ether functional group can offer air drying character, alcohol functional group can be taken esterify reaction, so TMPDE is widely applied in synthetic resin.

Along with the continuous advancement of society, market has higher requirement as to special resin character by higher hardness, clearance color, better corrosion resistance environmental character, and quicker speed of drying in the air, and TMPDE can offer such performance with special molecule structure, better physics character, which win preference of professional personage.
