Product Description

BW3-9009 is a 100% solids aliphatic polyurea elastomer formed through the reaction of an aliphatic isocyanate component and an amino compound component. Its application requires professional polyurea spraying equipment. This coating not only exhibits outstanding waterproofing, anti-corrosion and wear-resistant properties, but also features excellent aging resistance. It is ideal for outdoor applications without chalking or discoloration. This product is widely employed in industrial and commercial anti-corrosion and waterproofing applications.

Application Scope

BW3-9009 is used for anti-corrosion, waterproof and weather-resistant protective coating work in construction, chemicals, transportation, metallurgy, electric power, aerospace, marine, shipbuilding and other fields.

  • Outdoor Construction SurfacesProtective coating review for prepared roofs, exterior concrete and exposed structural surfaces.
  • Chemical and Industrial AreasAnti-corrosion and waterproof protection where acids, alkali, salts, oils or chemical splash may be reviewed.
  • Transportation, Metallurgy and Electric PowerWeather-resistant protective coating for compatible prepared industrial and infrastructure surfaces.
  • Marine, Shipbuilding and Aerospace-Related UsesExposed-surface protection where weathering, color appearance and anti-corrosion performance need project review.

Designed for Exposed Outdoor Protection with Color-Stability Review

BW3-9009 helps applicators build a seamless aliphatic spray-applied protective layer for exposed project surfaces. It is a suitable choice when outdoor service needs waterproofing, anti-corrosion protection, weather resistance and reduced chalking or discoloration compared with standard aromatic exposure routes.

100%Solids ContentBuilds a solvent-free protective film without solvent evaporation, helping support consistent coating thickness on exposed surfaces.
40-100 sGel TimeProvides a longer listed timing window for professional aliphatic spray work, detail coverage and surface finishing review.
1000 hArtificial AgingSupports outdoor weathering review with listed no blistering, cracking, rusting or peeling under the stated test.
Shore D 60HardnessProvides a harder exposed protective surface profile for anti-corrosion, waterproofing and wear-service review.

Product Features and Advantages

BW3-9009 is designed for exposed outdoor protection, combining aliphatic weathering performance with spray-applied waterproofing, anti-corrosion resistance and long-term surface appearance stability.

Film Formation and Application

  • Solvent-Free 100% SolidsBuilds film without solvent evaporation, helping maintain coating thickness and reduce shrinkage during cure.
  • Controlled Aliphatic Spray BuildSupports sprayed application on curved, sloped and vertical outdoor surfaces under suitable equipment settings.
  • Dense Seamless FlexibilityForms a continuous coating across prepared exposed surfaces, joints, corners and detail transitions.
  • Longer Gel-Time WindowThe listed gel time gives applicators a different working profile than fast aromatic spray polyurea products.
  • Durability SupportSupports outdoor protective service when substrate preparation, primer, UV exposure and maintenance conditions are confirmed.

Outdoor Protection Performance

  • Weather Resistance and Color-Stability ReviewDesigned for outdoor use where chalking, discoloration and gloss loss need to be reviewed with listed artificial-aging data.
  • Adhesion to Prepared SubstratesSupports bonding to steel, concrete, wood, glass fiber and other compatible substrates after proper preparation.
  • Impact and Abrasion ResistanceHelps protect exposed surfaces subject to wear, impact, maintenance access or industrial service conditions.
  • Chemical Resistance ReviewSupports anticorrosion review for acids, alkali, salts, oils and other listed media under stated test conditions.
  • Waterproof PerformanceForms a continuous protective membrane for compatible prepared outdoor substrates and structures.
