It has many excellent characteristics, in the low-molecular curing does not produce any harmful substances, no pollution, absolutely non-toxic, then a large depth can be completely cured, to the environment and long-term use at about 280 ℃, excellent electrical performance particularly.
Use: for self-regulating PTC heating ceramics, its high temperature resistance, good thermal conductivity, it is used extensively for PTC replace imported products.
Instructions：
1、Use according to A: B = 1: 1 weight ratio weighed in a clean container, stir (be original device bonding site for general processing).
2、On the original device may also be applied to the adhesive screen printing.

Precautions：
1、Do not mix organic matter and organic tin impurities such as nitrogen, phosphorus, sulfur and other elements, in order to avoid curing bad.
2、A, B component and the tools used to be separate dedicated (cause agglomeration after mixed, so that plastic scrap).Storage conditions: keep in a cool, dry place, duration: one year.
