Application environment
Environment temperature: -5 ~+ 35ºC
Relative humidity: ≤85%
Dew point: ≥3ºC
Application tips
Hand brush, roller
Air spray, air pressure 0.3-0.5Mpa
Airless spray, spray pressure 15-20Mpa
Recommended dft: 100-200 um
Re-coating interval: ≥2h
Application note
Agitate part B well prior to use.
Pour out the limited material to use promptly, to avoid moisture cure.
After coating application, proper heating (40-70ºC) is allowable to short the surface dry time, and improve the coating film property.
When the temperature below 15ºC, preheat the liquid material during spray, but it will reduce the pot life.
