Product Description

BW0-8029 is a two-component high-performance anti-corrosion decorative topcoat, which takes aliphatic polyaspartic resin prepolymer as the main film-forming material. It features excellent discoloration resistance and weatherability, along with outstanding UV resistance, effectively resisting fading and aging caused by sunlight irradiation. The product has good leveling property, strong adhesion to the substrate, and excellent wear resistance and chemical resistance, which can effectively isolate corrosive media and protect the substrate from damage. It is an environment-friendly, efficient and durable topcoat, suitable for various coating scenarios and compatible with subsequent coating layers.

Application Scope

BW0-8029 is used for anti-corrosion, protective and decorative coating on reinforced concrete and metal structure surfaces.

  • Reinforced Concrete SurfacesReview for prepared reinforced concrete surfaces where decorative protection and weather resistance are required.
  • Metal Structure SurfacesReview for prepared metal structures requiring anti-corrosion protection and exposed decorative finish.
  • Protective Decorative FinishUse as a thin exposed topcoat where color, gloss, chemical exposure and service conditions must be confirmed.
  • Aromatic PU or Polyurea TopcoatCan be reviewed as a topcoat over compatible aromatic polyurethane or polyurea coating surfaces.

Designed for Decorative Protection on Concrete and Metal

BW0-8029 helps applicators build a tough, glossy and color-stable polyaspartic topcoat over properly prepared reinforced concrete or metal surfaces. It is a suitable choice when the project needs decorative appearance, weather resistance, chemical-resistance review and thin-film finish planning.

20 MPaTensile StrengthSupports protective topcoat review under the listed ASTM D-412 test method.
1000 hArtificial Aging ResistanceSupports weather-resistance review under the listed accelerated-aging test condition.
1500 hSalt Spray ResistanceProvides listed laboratory salt-spray data for anti-corrosion review under the stated condition.
0.10 kg/m²Coverage at 60 μmGives a listed theoretical coverage reference for coating quantity and finish planning.

Product Features and Advantages

BW0-8029 supports thin-film protective decoration, helping applicators create a dense, glossy and weather-resistant topcoat with color stability, adhesion compatibility and anti-corrosion surface protection.

Film Formation and Application

  • Tough Dense Decorative FilmForms a tough, dense, full and bright coating with strong color appearance.
  • Weather and Color StabilityDesigned to resist color change, yellowing, chalking and aging while maintaining gloss and color retention.
  • System CompatibilityShows good compatibility with polyurethane, epoxy, chlorinated rubber, alkyd and phenolic coatings after project review.
  • Thin-Film Topcoat PlanningUse the listed 0.10 kg/m² at 60 μm theoretical coverage as a planning reference, then confirm final film build by TDS and project conditions.

Protection Performance

  • Wear and Impact ResistanceProvides listed abrasion and impact data for protective coating review.
  • Chemical ResistanceProvides chemical-medium resistance review for acids, alkali and salts under the listed test conditions.
  • Anti-Corrosion PerformanceSupports anti-corrosion protection for compatible reinforced concrete and metal structure surfaces.
  • Water ResistanceProvides listed 48 h water-resistance data with no bubbles, wrinkles, color change or peeling.
  • Service-Life SupportDurable protective performance can help reduce maintenance work and extend sprayed-structure service review.
