Category：powder Coating | Brand：MT
Introduction
Transparent powder coating is a clear or tinted powder coating designed to provide a smooth, transparent finish on compatible metal surfaces. Depending on the formulation, this product series uses polyurethane or acrylic resin with a curing agent to achieve high transparency and good surface leveling.
Different formulation types offer different curing conditions and coating properties. The series can be considered for decorative finishes, protective topcoats, and metal products where the appearance of the underlying surface or coating needs to remain visible. The appropriate formulation should be selected according to the substrate, required appearance, application process, and service environment.
