The features of the coatings powder : 

Main composition

Mainly made of epoxy resin,polyester resin and curing agent, leveling agent, pigment, filler and other addictives. it has super chemical resistance and mechanical properties. It can be used in painting those metal products that have special requirement of corrosion resistance, electric insulativity and pliability. Directly outdoor using is not to be suggested.

 

Products series

Available in standard curing and lower temperature curingAvailable in multi-colors, different gloss level such as high gloss ( above 90°), flat gloss( 70-80°), semi gloss ( 10-60°), matt( below 10°), particular color and gloss is made according to customers requirements.Available in various kinds of art textures, such as sandy, wrinkle, lanose grain, hammer tone, metallic effect etc.

Physical property

Specific gravity: 1.11.8g/cm3 (varied with different color and gloss)

Particle size: average 10~38um, proportion 10~84um > 90%, it can be adjusted if special requirement is put forward to us in advance.

 

 

Curing temperature

Standard type: 180oC/15 minutes

Or 160oC/20 minutes, 200oC/10 minutes if customer require

 

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

 

  

Coating method

Electrostatic spray gunTribo gunElectrostatic fluidized bedFluidized bed

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
