Petroleum Heat Resistant Powder Coating , Industrial High Heat Powder Coat

Powder coating for high temperature resistant


Introduction:

High temperature resistant coatings generally requires the film in 200 ℃ above does not change color, do not fall off, can still maintain appropriate physical properties of the coating. Usually, high temperature resistant coating is mainly composed of high temperature resistant resin, high temperature resistant paint, high temperature resistant fillers as well as the additives. The heat resistant powder coatings still is given priority to organic silicon powder coating


Application:

Chemical, petroleum, metallurgy, aviation and other industries.

Application Area: Can be widely used in Bridges, ports, airports, buildings, basements, high-speed rail, etc.

Applicable process: Electrostatic Coating

Notes:

1. Steel surface scale remove clean, reveal metal color; Steel surface roughness handling quality standard, appropriate for 50-70 - mm; Derusting grade level Sa2 1/2 (GB/T8923, no chloride attached on steel surface. Preheating: temperature should be controlled in 220-245 ℃.)

2. Product should be stored in ventilated, dry, indoor temperature below 27 ℃, away from heat, corrosive chemicals and chemical solvents, avoid bright light, the maximum stack height should not exceed 4 layers, avoid prolonged pressure, ensure airtight box. In case the clot and damp affects the fluidization performance.

3. As the product has high reactivity, it is recommended that storage period for 27 ℃ under 3 months for the best. Exceed shelf life, should be test its performance first.
