Powder coating described

By Judith Kimbers


Powder coating is an advanced technique for applying an attractive as well as protective finish to a range of materials and products. Powder coating is principally employed for coating of metals, for example domestic appliances, aluminum extrusions, and also automobile and cycle parts.

The powder coating process utilizes a solvent free blend of plastic resins, pigments, and fillers of which melt and join together with each other when heated. The solid pieces of coating will be electro statically charged in a spray gun and carried through low velocity air to the surface of the component being coated. The electrostatic charge holds the powder particles in position while the part is cured inside the high temp stove. The heat from the oven results in a chemical reaction to occur and the powder to cure, making a highly hard wearing surface finish that is more durable compared to a conventional paint.

Colour selection is practically unrestricted with high and low gloss, metallic and clear finishes available for purchase. Colours tend to be extremely hard-wearing, signifying they stay bright and vibrant longer. Texture choices vary from smooth surfaces to a creased or matte surface in addition to rough finishes made for concealing blemishes. These kinds of surfaces are robust, flexible, firm and highly resistant to cracking, flaking or colour fade.

Powder coating is a very attractive, durable, anti scratch, chemical resistant, and Ultra-violet resistant shell. Dependant upon the specific formulation applied, each one of these properties will change. Normally, epoxies exhibit good mechanical qualities nevertheless perform inadequately in direct sun light. Urethanes and polyesters display very good weather capability. Silicones exhibit top quality capacity to resist high temperatures.

Powder Coating is an eco-friendly process contrary to solvent - based wet paint. Now with Environmental protection agency rules growing ever tougher, powder coating is fast becoming a good choice. Since the powder coating approach doesn't utilize solvents in any way, VOC emissions are avoided.

Modern powder coating experts will likely have iTW Gema electrostatic coating machines in order to provide a high quality finish. A few firms could have specialized machinery able to apply polyester powder coatings to metal sheets up to three metres long, 1.5 metres broad and 400mm deep.

A large number of coated metals are usually subjected to a rigorous multistage, pre-treatment method to assure paint adhesion and sturdiness. Make certain that the organization that you chose provides a warranty for at least 5 years. Several corporations currently have in-house powder coating plant and pre-treatment facilities which enable it to give a range of services not just powder coating. These can include things like metal fabrication, conventional flat roofing trims and flashings as well as Wall Capping, Fascia Profiles and Soffits and complex architectural profiles such as balustrades and rainwater goods.
