Product Description

BW6-9539 is a single-component aliphatic polyurea waterproof and anti-corrosion coating that exhibits excellent adhesion to a wide range of substrates. Owing to the unique chemical structure of its aliphatic prepolymer backbone, this product not only delivers outstanding high elasticity, high tensile strength, abrasion resistance and impact resistance, but also possesses excellent corrosion resistance and weatherability. It resists chalking and discoloration under long-term outdoor exposure, while maintaining excellent decorative performance.

Application Environment and Guide

Stable coating performance depends on substrate treatment, application temperature, humidity, dew point, film thickness and recoating interval. Review the application environment and guide values before installation, and confirm final parameters with the latest TDS and project requirements.

Application Environment

Product data table
ConditionRequirement
Environment temperature-5°C to 35°C
Relative humidity35-85%
Dew pointFor metal surfaces, substrate temperature should be at least 3°C above the dew point
Metal surfaceSandblast to Sa2.5 according to ISO8501-1 or GB8923 where recommended
Concrete surfaceStrong, dense, flat, clean and dry; repair sanding, shelling, cracks or honeycomb with putty where needed
Wood surfaceClean and dry, without burrs, fragments or loose debris
Low-temperature handlingCan be used at -10°C; for low-temperature use, keep the paint bucket in an air-conditioned room for at least 24 h before application

Application Guide

Guide itemRecommendation
Theoretical coverage reference0.16 kg/m2 at 100 µm; final film build according to the latest TDS and project requirements
Recommended dry film thickness100-200 µm, or according to design requirements
Recoating interval6-30 h; if over 30 h or dust accumulates, sand and clean before recoating
Suggested painting methodsBrush, roller, air spray or high-pressure airless spray
Low-temperature useCan be used at -10°C; keep the paint bucket in an air-conditioned room for at least 24 h before low-temperature use
Material handlingStir evenly before use, pour out only the accurate quantity needed, and seal the bucket immediately
Thinner controlDo not add thinner without supplier guidance; call the manufacturer if viscosity changes with environment or humidity

Application Precautions

  • 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.
