Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electro-statically and then cured (by polymerization) under heat. The powder may polyester or epoxy. It is usually used to create a hard finish that is tougher than conventional paint.
Because powder coating does not have a liquid carrier, it can produce thicker coatings, usually of 40 micrometers. Therefore it is much more thicker than conventional liquid coatings and it doesn’t run, thus powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces. Because no carrier fluid evaporates away, the coating process emits few volatile organic compounds (VOC).
1. Powder coatings contain no solvents at all and release little or no amount of volatile organic compounds (VOC) into the atmosphere therefore they are not dangerous to the environment or to the people.
2. The coatings produces by using the powder coating method are much thicker than conventional liquid coatings, and this is without running or sagging.
3. Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.
4. Curing time is reduced with powder coating than liquid coating.
5. We can handle parts a long as 5 meters long, as 2 meters wide and as high as 2.8 meters.
6. We can paint in two layers if necessary, meaning a primer on top of the phospating surface, which is also a pre-treatment. Achieving thicknesses of 80 µm.
