What is Powder Coating?
Powder coating is a new type of 100% solid powder coating which does not contain solvents. With no solvent, no pollution, energy and resources saving, recycling, environmental protection, higher performance, low health risk to workforce, economical advantages etc.
Most powder coating is used by electrostatic spraying on metal surface, and then cure in oven, eventually form a solid layer.
Categories and Performances of Powder Coatings
♦Epoxy resin powder coating: Mainly used indoor, offer the best corrosion protection
♦Polyester resin powder coating: Mainly used outdoor, offer the highest exterior stability and performance
♦Epoxy Polyester Hybrid powder coating: could be used indoor or outdoor, offer the best corrosion and weather resistance

Introduction
Jinhu Color Powder Coating co.,Ltd has more than 10-year' experiecnce in producing the powder coating.
With experienced technology , we have achieved a good reputation at home and abroad.
Main composition
The bulk powder paint is 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.
Application
· Pipeline industry: anti-corrosion pipeline, Oil pipeline, sewage pipe, vessel water pipe, gas pipe and valves etc.
· Metal furniture: Steel furniture, documents cabinets etc.
· Kitchen utensils: gas cylinder, gas cooker, kitchen ventilator etc.
· Construction industry: door lock, rebar and steel moulding plate
· Electrical industry: Electronic spare parts, winding coil, and insulation coating of the rotator etc.
Products series
· Available in standard curing and lower temperature curing
· Available 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 |
Average coating rate
