  1. Brief Introduction
  CM633 is a polycarboxylic OH matting agent. It can suitable for EP and E/P powder coating. At 60^o gloss, the gloss can be reduced from 5-50% by using CM633.
  2. Specification

  Appearance	White fine powder
  OH Amount（g/eq）	About100
  Melting range（o）C	175~185
  Volatile（%）	≤1

  3. Properties
  ① Comparing to the Matting made of salt of an organic polycarboxylic acid with a cyclic amidiine, CM633 is more suitable for white and light color powder coating; CM633 won’t yellowish even though the powder coating is over baked.
  ② Very good mechanical properties.
  ③ The gloss of the powder coating will be affect little by the condition of extrude and bake temperature.
  4. Application
  ① Hybrid: Epoxy resin=CM633OH+polyester OH.Epoxy:CM633=11-12% Epoxy resin.
  ② CM633 have different effect in the different polyester resin, so need to adjust formulation. Hybrid: select high acid value or low acid value polyester.
  ③ Accelerate Agent will effect the matt result of CM633, so add 2-5% Accelerate Agent (ZC-1), as to get good mechanical properties and matting effective.
  ④ The fillers play important role to the flow of powder coating, suggest add non-particle filler in order to have good fluidity.
  ⑤ Extrude Temperature：110~120 ^oC.
  ⑥ Curing condition：190 ^oC/20~25min or 200 ^oC/15~20min.
