This product is used in other substrate materials. Please consult our company.
6. Construction conditions
Substrate temperature well painting is about -20~50°C. Please must use spraying when the temperature is above 40°C for substrate temperature. Please must add suitable thinner to adjust Dope viscidity in order to avoid dry spraying.
7. Construction methods
Spraying:airless spraying or air spraying. Recommending adopting high pressure airless spraying. Please pay more attention to adjusting paint viscidity and air pressure when adopting air spraying.
Brushing:Suggested that it is adopted when pre-Dope and small areas Dope, but it must reach dry film thickness.
Humidity:30-75% Atomizing pressure:4-6Kg/cm2
Wind speed:0.2-0.4m/s Gun distance:200-300mm
Spraying times:two times for thin amorphous phosphating Spraying swath:200-400mm
Film thickness:20-40µm Gun speed:0.2-0.8m/s
