|Spray Gun||Gravity feed: 1.4-1.8mm; 3-5kg/cm²|
Spray 2-3 coats, total should be 40-60μm
Drying time: 18-26 hours at 20 ℃; 60-80 minutes at 60 ℃
When the temperature is 10 ℃ lower, recommend to bake at 60-70 ℃ for 30 minutes.
Dry Sanding: P240-P400 Wet Drying: P600-P800
After drying and sanding, re-coat with putty, primer, primer surface and all kinds of topcoat
For oxidized iron and cast iron, shot blasted sa 2.5class with roughness of 30-75 μm, or acid wash
the oxidized parts to get rid of rust.
