1. Brief Introduction
Quick hardner CM31 is a heterocylic compound with azote. It enable comparison to the B31 (HüIs AG) IN HARDENING EFFECT. And be used in epoxy powder coating, it can help the coating to increase its mechanical properties and chemical resistance, provide its surface higher gloss and smooth. It can be applicable to epoxy-polyester powder in order to decreasing hardening temperature or quichening up hardening time.

5. Useage Level
In epoxy powder coating, the dosage of CM31 must accord to the mole of epoxy, and make sure by lab; In hybrid powder, the dosage is 0.3% of total mole, need make sure by lab. In order to obtain the best general capability.
CM31 is a high active product. In period of its producing, extrusive temperature shall not more than
