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
