Coating powderis a very durable method of providing a decorative
finish to metals and a range of other materials. Itoffers many
advantages over other finishes including:
· A wide range of finishes and colours including metallic,
glossy,rough and textured.
· Corrosion resistance.
· Powder coating can be applied to most metal components including
steel, Zinc, brass and aluminium.
· The durable finish provides a surface finish which is less prone
to chipping, marking and scratching.
· Powder coating can be applied to components used internally and
Powder coating is a dry finishing process that uses finely ground
powders of pigment and resin to coat the surface. Powder coating
uses an electrostatically charged technique in which the powders
are charged so that the powder particles adhere to the metal
surface and are then melted and fused together in the curing
In addition to a wide range of colors and textures, an almost
infinite range of properties can be bulit into the finish. Examples
include resistance to ultra-violet rays, enhanced durability and
better corrosion resistance. Thousands of different kinds of parts
and products are now powder coated. Examples include dryer drums,
refrigerator liners, hospital beds, metal furniture, electrical
cabinets, lighting fixtures, power saws, farm implements, curtain
rods, ceiling fans, light truck bodies, engine, suspension, frame
and other auto parts, motorcycle frames, bicycle frames, etc.

Powder Coating Colours
The list of powder coating colours is vast. Generally we cover all
the standard colours. RAL is a colour reference system that was
invented in 1927 by Reichsausschuss fur Lieferbedingungen in
Germany. While there is a wide choice of standard colours we can
also colour match any current corporate colours and produce custom

The main finish reflects the gloss level of the final product,
usually being Gloss, Semi-gloss or Matt. There is also the choice
between Flat finish, Rough finish, Texture finish, Metallic finish.
When choosing metallic powders Woncheng always use the more
expensive bonded powders as this gives a more uniform spread of
metallic particles on the end product. If your product requires a
metallic finish always ask if the powder is bonded or not.
