Application instructions
Environment temperature: -5 ~35ºC
Relative humidity: 35-85%
Dew point: when apply on metal surface, the temperature must be 3ºC higher than dew point.
Application guidance
Recommended dft: 500-1000um (or based on the design requirements)
Recoat interval: 2-4h, if exceed 24h or have dusts on the surface, use sandpaper to blasting then apply it.
Recommended application method: use scraper to scratch.
Notice
It can be used in the temperature below 10ºC. When apply in extreme low temperature, keep the coating barrel in the air conditioning room for 24 hrs.
STWD advises to mix the coating barrel uniform, seal the package well after use to avoid moisture absorption. Not to put the poured out material into the original barrel again.
Viscosity is fixed before shipped, thinner shall not be random added. Instruct the manufacturer in special situation to add thinner.
