Product Description

BW0-8028 is synthesized through the reaction polymerization of polyaspartic ester and polyisocyanate. As polyaspartic ester is an aliphatic sterically hindered secondary amine, and the selected curing component is an aliphatic polyisocyanate, the coating exhibits high gloss and excellent color retention, making it ideal for long-term outdoor applications. When the secondary amine groups react with isocyanate groups, a polymer network structure with high crosslinking density and interpenetrating polymer chains is formed, which endows the product with outstanding physical and chemical properties.

Review the main product, substrate, metal protection, application and document questions before specifying or ordering BW0-8028.

BW0-8028 is a polyaspartic coating formed from polyaspartic ester and aliphatic polyisocyanate chemistry. It is used where prepared metal surfaces need anti-corrosion protection, gloss retention, color retention and weather resistance.

The technical sheet lists steel structures, storage tanks, containers, valves, natural-gas pipelines, vehicle frames, axles, shelves, tank trucks, swimming pools, wastewater pools and chemical containment areas.

The technical sheet states it can be directly applied to metal surfaces as a topcoat direction. Final use still depends on rust removal, surface preparation, moisture condition and project-specific coating-system confirmation.

The technical sheet lists a 1:2 mixing ratio by weight, 1 h pot life at 25°C and a theoretical coverage reference of 0.15 kg/m² at 100 μm film thickness.

Use the listed theoretical coverage as a planning reference only. Final film build, coating method and recoating requirements should be confirmed with the latest approved TDS and project conditions.

Confirm immersion exposure, chemical medium, substrate preparation, primer or coating-system route, film build and test requirements before specification.

Buyers can request the latest TDS, SDS, application guidance, available test data and project-specific coating-system recommendation before ordering BW0-8028.
