Confirm temperature, humidity, dew point, substrate preparation, coating method, dry film thickness and recoating interval before applying BW6-9539.

Application environment & substrate treatment

Condition	Requirement
Environment temperature	-5 to +35°C
Relative humidity	35-85%
Dew point on metal surfaces	Substrate temperature must be at least 3°C above dew point
Metal surface	Sandblast to Sa2.5 according to ISO8501-1 or GB8923 where recommended
Concrete surface	Strong, dense, flat, clean and dry; repair sanding, shelling, cracks or honeycomb with putty where needed
Wood surface	Clean and dry, without burrs, fragments or loose debris

Application instructions

Guide item	Recommendation
Recommended dry film thickness	100-200 µm, or according to design requirements
Recoating interval	6-30 h; if over 30 h or dust accumulates, sand and clean before recoating
Suggested painting methods	Brush, roller, air spray or high-pressure airless spray
Low-temperature use	Can be used below -10°C; keep the paint bucket in an air-conditioned room for at least 24 h before low-temperature use
Material handling	Stir evenly before use, pour out only the accurate quantity needed, and seal the bucket immediately
Thinner control	Do not add thinner without supplier guidance; call the manufacturer if viscosity changes with environment or humidity

Application tips

BW6-9539 is single-component, so no A/B ratio mixing is required; stir the coating evenly before each use.
Pour out only the accurate quantity needed for one application period, seal the bucket immediately, and do not pour unused material back into the original pail.
If low-temperature application is planned, keep the paint bucket in an air-conditioned room for at least 24 hours before use.
The factory-adjusted viscosity should not be changed with thinner unless the supplier gives specific guidance.

Why is BW6-9539 suitable for long-term outdoor exposure?

The data sheet describes BW6-9539 as an aliphatic polyurea coating with excellent weatherability, anti-aging performance, non-chalking and non-discoloration behavior for outdoor use, while maintaining good decorative performance.

How can BW6-9539 be applied?

The data sheet lists simple application by brush, roller, air spray or high-pressure airless spray. The application method should be selected according to project area, substrate condition, required film thickness and site controls.

What dry film thickness and recoating interval are recommended?

The data sheet recommends 100-200 micrometers dry film thickness, or according to design requirements. The recoating interval is 6-30 hours; if the interval exceeds 30 hours or dust accumulates, sand and clean the surface before recoating.

What substrates can BW6-9539 bond to?

The data sheet lists excellent adhesion to steel, concrete, wood, fiberglass and other substrates. Metal surfaces are recommended to be sandblasted to Sa2.5, concrete should be strong, dense, flat, clean and dry, and wood should be clean, dry and free of burrs or loose debris.

Does BW6-9539 need component mixing before application?

No component ratio mixing is required because BW6-9539 is a single-component coating. The data sheet still recommends stirring the coating evenly before use, pouring out only the accurate quantity needed each time, and sealing the bucket immediately after use.
