Application Data
Method of application : Conventional spray application
Thinner : PU Thinner
Thinning ratio (per kilogram): Use 60% to 100% for ease of application depending on the gun type .
Available Pack Size: 4LY、4LF、18LF、20LY、200LY
At a temperature of 23 ℃ and a relative humidity of 50%:
Drying time: Refers to 20-60 minutes of touch drying;
Finger press drying: 2-6 hours (actual drying time may vary depending on temperature, humidity, and wind speed)
Theoretical paint consumption:12 square meters/liter/coat. (Dry film thickness:25-30 microns, actual coating area may vary depending on construction method, surface roughness, and construction environment).
Application Steps
1. Substrate Preparation: For blanks or boards, sand with 320-mesh sandpaper; for topcoats, sand with 400-600-mesh sandpaper.
2. Paint Proportioning: The ratio of base coat:hardener:thinner=1:0.5:1.
3. Primer Process: After spraying the first coat of primer, allow air-drying for 5 hours, then sand and re-spray the second coat of primer. A third re-spray is optional if necessary. (Note: The amount of thinner can be appropriately reduced during re-spraying.)
4. Color Adjustment: After primer spraying is completed, color-adjusting oil can be used for color adjustment or color modification.
5. Glazing: Select the required gloss level and apply the corresponding.
