The difference between powder and paint spraying

Paint and powder spraying (plastic) are generally called spraying, the following for everyone to explain the difference between painting and powder spraying.

1. Paint selection

Spray paint, including fluorocarbon paint, acrylic paint, epoxy resin paint and polyurethane paint

Powder spraying (plastic), the use of paint for powder coating, commonly known as plastic powder, the primary types are: epoxy polyester powder coating (indoor and outdoor two types) epoxy powder coating (anticorrosive powder). Simply speaking, paint needs solvent and curing agent to be mixed and used into liquid state, and powder is powder solid state

2. Spraying parameters

Painting and powder spraying can be suspended for spraying first, or can be done separately in a small spraying room. Paint can be sprayed by electrostatic or non-electrostatic air. Powder spraying must be electrostatic spraying, friction gun spraying, fluidized bed spraying and other methods.

3. Baking temperature

Paint drying temperature: 60-220 ℃, 15-60min. Distinguish according to paint characteristics

Drying temperature of powder: 180 ℃ to 200 ℃, 10 to 20min. Distinguish according to powder characteristics

4. Adhesion

Both of them can reach the level 0 standard under normal painting

5. Thickness of paint film

Paint: 15-120 μ m. Coating film varies according to paint composition

Powder spraying: 60-120 μ m, which varies according to the type.

6. Color types

Paint: Plain, metallic.
