Application guide

Application conditions and instructions.

Confirm site temperature, humidity, dew point, substrate preparation, coating thickness and recoating interval before applying BW6-9528.

Application environment

Confirm temperature, humidity and dew point before application, especially on metal surfaces.

Condition	Requirement
Environment temperature	-5 to 35°C
Relative humidity	35-85%
Dew point	When applying on metal surfaces, the surface temperature must be at least 3°C higher than the dew point temperature.

Application instructions

BW6-9528 is designed for brush, roller or high-pressure airless application without specialized polyurea spray equipment.

Guide item	Recommendation
Recommended dry film thickness	300-1000 µm, or as design requirements
