Guia de aplicação

ApplicationProcess

1

Preparo de superfície

Thoroughly degrease and degrease the substrate, clean to remove oxide scale, oil stains, and rust. Sandblast steel to Sa2.5 grade with roughness Rz40-75μm. Acid pickling and passivation or chromate treatment for aluminum. Remove all contaminants to ensure the surface is clean with no residue. Ambient temperature 5-40°C, relative humidity<85%。

2

Primer / pré-tratamento

Select a matching primer or pretreatment based on the substrate and system. Powder coatings can be applied directly to sandblasted substrates without a primer. Water-based paints require a dedicated water-based primer to seal the substrate. Strictly control primer film thickness and drying conditions according to product requirements.

3

Aplicação da camada principal

Powder coatings are applied evenly by electrostatic spraying (corona or tribo). Water-based industrial paints are applied by high-pressure airless spraying or air spraying. Strictly control application parameters such as film thickness/environmental temperature and humidity/flash-off time. Before baking, check that the coating is uniform with no missed areas and no sagging.

4

Baking Curing

Powder coatings are baked at 180-200°C for 10-20min to fully cure, melt, level, and form a film. Water-based paints are low-temperature baked at 60-80°C or air-dried at room temperature. Oven temperature uniformity ±5°C, gradually increase temperature to avoid pinholes and bubbles. After curing, naturally cool to room temperature.

5

Inspeção e embalagem

Test performance indicators such as film thickness/gloss/adhesion/hardness/impact resistance/salt spray resistance. For powder coatings, check coating uniformity and degree of cure (solvent rub method). For water-based paints, check water resistance and weather resistance. After all pass, package and ship in a dust-free manner.
