Packing
A: 25 kg iron drum or other
B: 20 kg plastic drum or other
Cautions
1. Cautions in use
a) Part A should be agitated before use to disperse sufficiently the settled filler. Or heat it to 40℃until it is completely dissolved.
b) Weigh both A and B respectively, into specified amounts and mix them uniformly.
2. Cautions in handling
a) It is better to potting in vacuum condition, the mixture should be usd up in permitting time.
b) Cure in room temperature or heat to 60℃, usually items cure under the condition of 25℃/24h or 60℃/2~3h
