The gloss of powder coatings is one of the processes that need to be controlled during the production. This article will mainly introduce powder coatings and gloss meters for powder coatings.
What is a powder coating?
Powder coating is a new type of solvent-free 100% solid powder coating. It is solvent-free, non-polluting, recyclable, environmentally friendly, saves energy and resources, reduces labor intensity and high mechanical strength of coating film.
The largest growth areas in China's powder coatings market are: the marine industry and the pipeline industry. The problem is that the impact resistance and hygroscopicity need to be improved, and the researchers focus on the modification of various base materials. The Chinese produced pipeline anti-corrosion epoxy powder coating is applied in terms of storage stability and coating construction, and there is still a certain gap compared with international high-quality products.
Due to advances in international automotive powder coating preparation technology, automotive glazing, wood and plastic coatings are the most dynamic potential markets. The automotive industry will be a major consumer, and the powder coatings market in Greece, Turkey and Eastern Europe is growing very well. The Asia Pacific market has greater market potential and is considered to be the fastest growing region in the world.
Gloss Meter for Powder Coating Process
The powder coating is prepared by mixing special resin, pigment filler, curing agent and other auxiliaries in a certain ratio, and then through hot extrusion and smashing. They are stored at room temperature, stable by electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dip coating (thermoplastic method), and then baked, melted and solidified to form a flat and bright permanent coating film to achieve decoration. For the purpose of corrosion protection, the final coating film gloss can be measured using a gloss meter for powder coating, and the uniformity of the film can be judged by the gloss data.
Gloss Meter for Powder coating can strictly monitor parameters and help companies set production targets and verification standards. For more product information, please refer to "LS191 Gloss Meter for Powder Coating".
