General Description The use of non-halogen flame retardant epoxy laminates

is being greatly increased with the growing demand of

low environmental pollution electronic appliances

recently. EPOKUKDO KDP-550MC65 shows excellent

properties such as dimension stability of cured Epoxy

Resin, good electrical properties, strong mechanical

strength & adhesion strength, excellent chemical

resistance and processing property. Besides the

characteristics described above, it shows good heat

resistance and non-halogen flame retardancy as well.
