● Standard operating procedure
|
To achieve optimal coating results, we recommend following the following steps:
Substrate pretreatment: Steel is thoroughly degreased, degreased and sandblasted to obtain a clean, active surface with appropriate roughness.
Electrostatic spraying: Use our electrostatic spray gun for dry powder spraying to ensure uniform adsorption of powder.
High-temperature sintering: Sintering at a precise temperature of 850-860°C causes the powder to melt and chemically react with the substrate to form a strong enamel coating.

● Recommended application areas
 |
· Building exterior walls and roof steel plates
· Household appliances (such as ovens, water heater liners, barbecue grills)
· Anti-corrosion parts of chemical facilities
· Outdoor signs and metal furniture
|
● Product advantages
|
Super adhesion: It reaches the first-level adhesion standard, and the coating is firmly bonded to the substrate, effectively resisting peeling and impact.
Excellent leveling and gloss: brightness ≥90, ensuring that the coating surface is smooth and flat, presenting a high-quality texture.
Efficient construction performance: Excellent fluidization performance (≥80g/30s) ensures smooth spraying process, uniform coverage, and improves production efficiency.
Wide adaptability: Provide coating thickness options of 160-300μm to meet the needs of different application scenarios for protection levels.
