Powder coating thickness gauge
The powder coating is a solid powdery synthetic resin coating composed of a solid resin, a pigment, a filler, and an auxiliary agent. Unlike solvent-based and water-based coatings, its dispersion medium is not solvent and water, but air. The powder coating may be a thermoplastic or a thermoset polymer. It is used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminum extrusions, drum hardware and automobile and bicycle parts.
Thermoplastic powder coatings have poor coating appearance (gloss and leveling) and poor adhesion to metals, so they are rarely used in automotive coating applications. Automotive coatings generally use thermosetting powder coatings.
The powder coating thickness gauge measures the thickness of the paint film and can be used to verify the appearance of the paint film formed by the powder coating and whether the corrosion resistance meets the requirements of automotive finishing.
Powder coatings are processing consumables products, with low investment thresholds and fierce market competition, which also caused the phenomenon of mixed wheels in the powder coating market. In addition, the powder coating is a powdery substance, which is not easy to identify, and will cause a large economic loss to some enterprises that use powder coating. The powder coating thickness gauge can be used to detect the thickness of the film after film formation, which can help to check whether the powder coating has cut corners.
