  Detailed Description:

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.
