The differences between baking paint and powder coating include: powder coating has poorer gloss and roughness compared to baking paint; powder coating is generally thicker than baking paint; it offers better adhesion and corrosion resistance than baking paint; powder coating requires higher curing temperatures and typically uses electrostatic application, while baking paint generally requires lower temperatures; surface treatment for powder coating can be simpler, not requiring a primer, whereas baking paint needs a primer during application. Baking paint is an industrial paint, divided into two types: water-based metal paint and oil-based metal paint. Water-based metal paint is an environmentally friendly coating using water as a solvent, while oil-based metal paint uses organic solvents. The method involves roughening the material slightly and then applying some paint. Baking paint is non-sticky, making the coating less likely to adhere to other substances, while the film exhibits good bonding properties. Additionally, baking paint is heat-resistant and has low friction. It offers excellent wear resistance under high loads, combining the dual advantages of wear resistance and non-adhesion under certain loads. Baking paint is resistant to chemical erosion, protecting components from any kind of chemical corrosion. Powder coating does not require thinners, making the process environmentally friendly and non-toxic to humans. The coating appearance is excellent, with strong adhesion and mechanical strength. The spraying process is shorter, and the coating's wear resistance is significantly higher, not requiring a primer. Some construction sites explicitly require the use of electrostatic spraying, which avoids the common flow issues seen in conventional spraying processes.
