Matt Hardener Used For Epoxy Polyester Powder Coatings

Introduction

It is a thermosetting powder coating based on epoxy polyester resin with excellent smooth glossy and good flow-out 

finishes. Its outstanding overbake yellowing resistance and mechanical properties make it a wide range of indoor applications,e.g.domestic appliances, home and office furniture,light fixtures, shelvinggs, machinery, ceiling panels, 

switchboards etc. Texture finish is also available.

The raw materials of Powder coating are resins, pigments, fillers, hardener ect. Compared with liquid paint, powder coating 

is environmental friendly and can reduce costs. Powder coating can form a harder finish than conventional paint and can be 

applied more efficient. While it also has disadvantages, it is not good for large and heat-sensitive objects. Usually the thickness 

of film by powder coating is >30 μm.

Matt Hardener QX- 68 is a composed salt of cyclic-amidine and multi-acid. It utilizes the two different reaction rates of group in 

molecular structure, and during the curing process, it generates nonuniform shrinkage then forms the matt surface. It has both 

gloss decreasing and curing functions.
