Pros and Cons
Advantages: no need for thinners, no toxicity, no environmental pollution, good coating quality, very high adhesion and mechanical strength, corrosion resistance, short curing time, no need for primer, low technical requirements from workers, high utilization rate of powder recovery.
Disadvantages: coating very thick, surface effect corrugated, not smooth, only semi-matte, breaks down under UV rays.
The added thickness of the coated layer makes it necessary to plug and mask holes or other tolerance-tight surfaces that will play a functional role.
Pricing of powder coats can be inconsistent between colors, finishes and part geometry.
Most polymers used for powder coating have poor electrical conductivity.
