What is powder coating？
Powder coatings are solvent-free, solid powder coatings consisting of resins, curing agents, pigments, fillers and additives.
These coatings are usually applied by electrostatic spraying, where the powder is sprayed onto the surface of a pre-treated substrate and then heated to melt, level and cure the powder to form a hard, durable coating film.
The main features of powder coating include:
√Environmentally friendly
√High Efficiency.
√Durable
The application of powder coatings is very wide, covering a wide range of industries such as construction, automotive, home appliances, furniture and so on.
How the powder coating process works ？
Powder Preparation →Substrate Pretreatment→ Electrostatic Spraying → Melt Curing →Cooling
This protective coating can be used both indoors and outdoors. As a manufacturing process, powder coating has excellent properties:
·Water resistance
·Heat resistance
·Weather resistant
·Corrosion resistance
Choosing the right colour and finish ？
One of the advantages of powder coating is the wide range of colours and finishes available.
Most powder coating suppliers will stock a range of colours (using RAL colour codes), making colour ordering quick and easy! Each RAL colour is available in several different gloss levels, providing even more choice!
1. Determine the environment of use
Indoor or outdoor? The difference in environment between indoor and outdoor use will affect the choice of colour. Items used outdoors need to take into account the effects of UV rays and choose a more weather resistant colour.
2. Functional requirements
Abrasion resistance: For surfaces that require high abrasion resistance, choose a hard powder coating.
3. Surface texture
Smoothness: For products seeking a high quality appearance, a smooth and delicate surface finish may be preferred.
Texture: Certain products may be suitable for surface finishes with texture, such as sand grain, orange peel, etc. This not only adds to the aesthetics, but also improves the feel or reduces fingerprint residue.
