Product Description

BW8010 Two-Component Solvent-Free Polyurea Primer is mainly composed of high-performance polyurethane resin prepolymers and polymer materials as film-forming components, manufactured through scientific production processes. The primer is solvent-free, odorless and environmentally friendly, causing no impact on the surrounding environment during application. It exhibits strong permeability to substrates and excellent sealing performance, and can significantly enhance the adhesion of the base layer.

Application Scope

BW8010 is used as an anti-corrosion and waterproof primer coating on concrete, marble, ceramic tile, wood, metal and compatible prepared substrates before follow-up coatings.

  • Concrete SubstratesPrimer review for strong, dense, flat, clean and dry concrete before compatible coating systems.
  • Marble and Ceramic TileSurface wet-out and adhesion support after cleaning, decontamination and compatibility review.
  • Wood SubstratesPrepared wood surfaces can be reviewed where the surface is clean, dry and free of burrs or loose debris.
  • Metal SubstratesMetal use requires rust removal and surface preparation to the specified standard before primer selection.

Designed for Solvent-Free Primer Preparation

BW8010 helps applicators build a sealed primer interface on properly prepared substrates before the following coating layer, while supporting adhesion, chemical-resistance review and waterproof coating preparation.

≥98%Solid ContentSupports dense primer film build without relying on solvent evaporation.
3.5 MPaAdhesive StrengthThe data supports adhesion review on dry concrete surfaces after proper preparation.
-40 to +150°CTemperature VariationThe listed 24 h temperature-variation test result is normal under the stated condition.
30 dAlkali ResistanceLists no corrosion, blistering or peeling under the stated 50% NaOH test condition.

Product Features and Advantages

BW8010 focuses on solvent-free primer preparation, helping build a sealed interface with high-solids film formation, substrate penetration, adhesion improvement and following-coat compatibility.

Sealing and Application Support

  • Adhesion ImprovementHelps improve adhesion between the substrate and the following compatible coating.
  • Sealing and PenetrationStrong substrate permeability and sealing performance help prepare the base layer before coating build-up.
  • Water and Moisture ResistanceSupports waterproof and moisture-resistance review for prepared compatible substrates.
  • Compatibility With Following CoatingsDesigned as a primer step before compatible coating layers, not as the main membrane layer.

Protection Performance

  • Chemical Medium ResistanceSupports acid, alkali, salt, salt spray and oil-resistance review under stated conditions.
  • Temperature Variation ResistanceThe physical table lists temperature-variation resistance under the stated laboratory test condition.
  • Bubble Reduction SupportHelps reduce bubble generation when used with proper substrate preparation and compatible following coats.
  • Odorless and VOC-Free ProfileBW8010 is positioned as odorless and VOC free; review SDS and project requirements before use.

Surface Preparation and Application Notes

  • Concrete substrates should be fully cured, clean, dry, dense and free of grease, stains, loose material and visible damage.
  • Metal surfaces should be sandblasted and derusted to Sa2.5 according to ISO8501-1 or GB8923 where applicable.
  • Before use, make sure raw materials are accurately proportioned and evenly mixed. The mixed paint must be used within 30 minutes.
  • Do not return remaining mixed material to the original bucket, and do not add thinner without manufacturer guidance.
