Product Description

BW6-8526 is a one-component aliphatic polyurea anti-corrosion and waterproof protective coating. Prepared via prepolymerization using high-strength resin, aliphatic isocyanate and special functional additives, the coating features high viscosity and is suitable for application by scraper. This product exhibits outstanding high elasticity, high strength, wear resistance and impact resistance, as well as excellent anti-corrosion performance and weather resistance. It shows no chalking or discoloration after long-term outdoor exposure and delivers desirable decorative effects.

  • Building roof waterproofingOutdoor waterproofing where aliphatic weathering performance and a thicker protective build are required.
  • Dams and hydropower buildingsWaterproofing and protective coating review for water conservancy and hydropower building surfaces.
  • Industrial protective surfacesPrepared steel, concrete, wood and glass-fiber substrates can be reviewed with the listed substrate-treatment requirements.

Designed for Outdoor Thick-Film Protective Coating

BW6-8526 helps applicators build a thicker aliphatic protective layer by scraper application. It is a suitable choice when the project requires waterproofing, corrosion protection, wear resistance and outdoor color-stability review.

24 MPaTensile StrengthProvides strong mechanical resistance for demanding outdoor surfaces and protective coating service.
400%ElongationHelps the coating accommodate movement while maintaining a continuous protective film.
2000 hArtificial Aging ResistanceSupports outdoor weather-resistance review under the listed accelerated-aging test condition.
2000 hSalt Spray ResistanceSupports corrosion-protection review where salt spray resistance is part of the project requirement.

Product Features and Advantages

BW6-8526 is built for hand-scraped thick-film protection, combining higher one-pass film build, aliphatic outdoor durability, waterproofing, corrosion protection and wear resistance for prepared project surfaces.

Film Build and Application

  • High Solid ContentHigh solid content and low VOC emission support thick-film build with less dependence on solvent evaporation.
  • Scraper-Applied Thick FilmHigh viscosity is suitable for scraper application; final dry film build should be confirmed by the latest TDS and project design.
  • One-Component HandlingNo component ratio mixing is required, helping reduce field preparation steps.
  • Wide Application Temperature RangeThe technical sheet lists service use from -50°C to 120°C.

Protection Performance

  • Waterproof PerformanceProvides waterproof protection for bridge maintenance, building roofs, dams and hydropower station buildings.
  • Wear and Impact ResistanceGood abrasion and impact resistance support demanding protective coating service.
  • Chemical ResistanceCan be reviewed for selected acids, alkalis, salts, oils and organic solvents according to the listed data.
  • Outdoor WeatheringAliphatic chemistry supports long-term outdoor review with non-chalking and non-discoloration claims from the technical sheet.
