Product Description

BW3-562 is a 100% solids aromatic polyurea elastomer formulated for application with compatible portable spraying equipment. It provides an alternative for projects where conventional plural-component high-pressure spray equipment is not practical. Equipment selection, operator training, output, mix control, film thickness and site suitability must be confirmed against the latest approved TDS and application guidance.

Application Scope

BW3-562 is used for anti-corrosion and abrasion-resistant coating work on pickup truck cargo boxes, vehicle chassis armor, vibrating feeders, mixer linings, impeller surfaces, pump housing liners, EPS foam scenery props and local repair of spray-polyurea project surfaces.

  • Vehicle SurfacesReview for pickup truck cargo boxes, vehicle chassis armor and compatible prepared vehicle surfaces.
  • EPS Foam Props and ScenerySupports surface reinforcement and protective coating review for EPS foam sculpture, film scenery props and custom shaped objects.
  • Small Parts and LinersUsed for vibration bowls, impeller surfaces, pump housing liners, mixer liners and similar prepared equipment surfaces.
  • Local Repair and Small AreasSuitable for local spray-polyurea surface repair and small-area work after surface preparation, sealing route and trial spray are confirmed.

Designed for Portable Cold-Spray Work on Small or Irregular Surfaces

BW3-562 helps applicators build a seamless protective layer with compatible portable cold-spray equipment. It is suited to smaller parts, shaped objects, liner areas, vehicle surfaces, EPS foam props and local repair work where organizing a full project-scale hot-spray setup is not practical.

100%Solids ContentBuilds a solvent-free protective film without solvent evaporation, helping support dense coating build on prepared small surfaces.
50-60 sGel TimeSupports a controllable cold-spray workflow for shaped parts, liners, foam props and local repair details.
16 MPaTensile StrengthProvides mechanical resistance for coated parts exposed to handling, abrasion, impact or protective service conditions.
410%ElongationHelps the elastomeric layer flex with shaped objects, edges, curves and prepared surfaces after proper preparation.

Product Features and Advantages

BW3-562 makes small-area and irregular-surface polyurea protection easier to organize, using portable cold-spray application to build flexible, dense protective films on compatible prepared surfaces.

Film Formation and Portable Application

  • Portable Cold-Spray SetupDesigned for compatible portable cold-spray equipment, helping reduce setup burden for small or local coating work.
  • Adjustable Reaction and Cure WindowReaction and curing time can be adjusted from 2-10 minutes for practical cold-spray application.
  • Spray Build on Irregular SurfacesSupports sprayed formation on curved, sloped, vertical and shaped surfaces without sagging under suitable conditions.
  • Dense Seamless FlexibilityForms a dense, seamless coating that can flex with shaped objects, liners and detail surfaces.
  • Convenient Small-Area WorkSimple application helps pickup beds, chassis armor, liners, EPS foam props and local repair work move more efficiently.

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 pickup beds, liners, impeller surfaces, pump housings and other parts exposed to wear.
  • Chemical Resistance ReviewSupports anticorrosion review for acids, alkali, salts, oils and other listed media under stated test conditions.
  • Waterproof PerformanceForms a continuous protective layer for compatible prepared substrates and small structures.
  • Temperature Variation StabilitySupports service review where coated parts may face temperature variation after curing.
  • Local Repair SupportCan be reviewed for local repair of existing spray-polyurea project surfaces after compatibility and trial application.

Application Note

  • For metal surfaces, review blast cleaning to Sa2.5 according to ISO 8501-1 or GB 8923. For concrete, prepare a firm, dense, flat, clean and dry surface. For wood, keep the surface clean, dry and free of burrs or loose fragments.
  • Use BW3-562 at the required material temperature. If product temperature is too low, warm it to around 35°C according to the latest application instruction before use.
  • Spray polyurea within the proper interval if the substrate surface is primed. For BW polyurea primer application and recoat interval, refer to the related Colorful Whale Advanced Materials (Shanghai) Co., Ltd. brochure.
  • Always apply BW3-562 on a small area before larger application to check that the mix ratio, color and spray effect are correct.
