Enamel powder = inorganic glassy powder (mainly silicate), fired at a high temperature of around 800℃;
ordinary electrostatic powder = organic resin powder (epoxy/polyester), cured at a low temperature of 180–200℃.
Enamel Powder
Equipment: High-temperature kiln (800℃) + dedicated electrostatic spray gun + high-temperature resistant recovery system.
Cost: Expensive equipment, high energy consumption, high unit cost; suitable for high value-added, high-requirement products.
Risks: High-temperature deformation, substrate limitations, dust abrasion of equipment (high hardness).
Ordinary Electrostatic Powder
Equipment: Conventional spray booth + recovery + 180℃ curing oven; industry-standard.
Cost: Inexpensive equipment, low energy consumption, low batch cost; suitable for mass-market hardware and home appliances.
In short:
Enamel powder: Inorganic glass powder, fired at 800℃, as hard as porcelain, high temperature resistant, strong corrosion resistance, expensive, used in high-end kitchens and bathrooms/chemicals/outdoors.
Ordinary electrostatic powder: Organic resin powder, cured at 180℃, like plastic, susceptible to high temperatures, moderate corrosion resistance, inexpensive, used in conventional hardware/home appliances.
