Pure polyester powder coating is made of polyester resin with
hardening agent. It has excellent weather resistance, so it is
usually called durable powder coating.
Applications:
Pure polyester powder coating can be used for outdoor products ,
auto industry , transportation equipments , air conditioner
external unit , highway protection fence, armrest ,fences and so
on.
Product series:
Products of different gloss and colors are available: high gloss (
above 80%), semi gloss (50%-80%), flat gloss(20%-50%), no
gloss(below 20%). And provide sand textured, wrinkle, hammer, rain patterns, moire,
crack, textured, point spread, transparency and other art textured
powder coating.
Curing Condition:
200ºC (workpiece temperature), 15 minutes.
Pre-treatment:
The overall quality of the coating system is largely dependent on
the type and quality of the pre-treatment. The recommended types of
pre-treatment for the most frequently used substrates are:
| Aluminium | Chromate conversion |
| Steel | Zinc phosphate |
| Zinc coated steel | Zinc phosphate or chromate conversion |
Average coating rate:
A. Smooth Surface:
6-12/KG, film thickness 60μm (calculated according to 100 consuming
of powder coating)
B. Texture Surface:
5-7/KG,film thickness is about 80-120μm
Film performance

| Heat & humidity resistance | GB/T 1740-1979 | ISO6270 | >500 Hours,film gloss slightly lose |
| Note: 1. Above test are using 0.30mm thickness degreased, rust
removed cold rolling steel plate, film thickness is 60-80um. 2. Film performance may slightly decrease with gloss decrease. | |||
