Powder Coat - Matt paint

Matte powder coating is an electrostatic powder coating process in which specially formulated matte powder is electrostatically deposited onto the surface of a metal workpiece, then melted, cross-linked, and cured at high temperature to form a low-gloss, diffuse-reflective solid coating. The matte effect is achieved through the use of matting agents and specific resin formulations in the powder coating, rather than through post-coating sanding or polishing. It can effectively conceal CNC tool marks, minor dents, and small surface pinholes, while providing better corrosion and wear resistance than conventional liquid paint. It is widely used for equipment enclosures, appliance housings, and structural or cosmetic metal parts.

A relatively thick coating can be achieved in a single application. For example, a coating thickness of 100–300 μm may require 4–6 applications with conventional solvent-based paint, while powder coating can achieve the same thickness in a single application. The resulting coating also provides excellent corrosion resistance.
Electrostatic powder coating and other advanced processes offer high production efficiency and are suitable for automated coating lines. Powder utilization is high, and excess powder can be recovered and reused.
In addition to thermosetting powders such as epoxy, polyester, and acrylic, a wide range of thermoplastic resins can also be used as powder coatings, including polyethylene, polypropylene, polystyrene, fluorinated polyether, nylon, polycarbonate, and various fluorinated resins.
