Application Scope

BW3-9512 is used for anti-corrosion protection of petrochemical storage tanks, bunds, towers, wash tanks, pipelines, sewage pools and related facilities.

  • Petrochemical Storage TanksProtective lining review for prepared tank interiors and storage structures exposed to demanding service conditions.
  • Bunds and Containment AreasAnti-corrosion and waterproof protective coating for prepared containment surfaces around chemical or oil-handling areas.
  • Towers and Wash TanksSpray-applied protective coating review for prepared equipment surfaces after substrate and exposure confirmation.
  • Pipelines and Sewage PoolsDense polyurea protective lining for compatible prepared pipeline, sewage and industrial liquid-contact structures.

Designed for Hard, Continuous Protection in Petrochemical Service

BW3-9512 helps form a dense, harder spray-applied polyurea lining for storage tanks, bunds, towers, wash tanks, pipelines and sewage pools. It is a suitable choice when the project requires continuous anticorrosion waterproof protection, chemical-resistance review and stronger mechanical support under confirmed service conditions.

100%Solids ContentBuilds a dense lining without solvent evaporation, helping maintain film build on containment and liquid-contact surfaces.
25-35 sGel TimeSupports controlled spray build on tank walls, curved surfaces, vertical areas and detailed transitions under the stated condition.
40 MPaTensile StrengthProvides stronger mechanical resistance for prepared tanks, pipelines and containment structures in protective lining service.
Shore D 72HardnessGives the cured film a harder protective profile for heavy-duty corrosion, wear and maintenance exposure review.

Product Features and Advantages

BW3-9512 emphasizes dense lining formation, harder film strength and heavy-duty service resistance, supporting protective coating systems exposed to industrial corrosion, liquid contact and mechanical wear.

Film Formation and Application

  • Solvent-Free 100% SolidsBuilds film without solvent evaporation, helping support dense lining formation and consistent film build.
  • Controlled Spray BuildSupports sprayed application on tank walls, curves, slopes and vertical surfaces without sagging under suitable conditions.
  • Dense Seamless LiningForms a continuous protective layer across large areas, joints, corners and equipment details after proper preparation.
  • Harder Film ProfileThe listed Shore D hardness and tensile strength support a tougher lining profile for heavy-duty service review.
  • Durability SupportSupports long-term corrosion protection when medium, primer, film thickness, installation quality and maintenance are confirmed.

Heavy-Duty Protection Performance

  • Adhesion to Prepared SubstratesSupports bonding to steel, concrete, wood, glass fiber and other compatible substrates after proper preparation.
  • Impact and Abrasion ResistanceHelps protect lining surfaces exposed to maintenance wear, impact or demanding industrial service conditions.
  • Chemical Resistance ReviewSupports anticorrosion review for acids, alkali, salts, oils and other listed media under stated test conditions.
  • Waterproof and Impermeable ProtectionForms a continuous barrier for compatible tanks, containment areas and liquid-contact structures.
  • Temperature Variation ResistanceHelps the protective lining handle temperature-change stress after substrate and service conditions are confirmed.
