BW0-8028 is used for anticorrosion and protection of steel structures, storage tanks, containers, valves, natural gas pipelines, frames, axles, shelves, tank trucks, swimming pools, sewage pools and chemical cofferdams.

Q: Why is BW0-8028 suitable for outdoor metal protection?

BW0-8028 uses polyaspartic ester and aliphatic polyisocyanate chemistry to provide high gloss, color retention, UV resistance, anti-yellowing performance and weather resistance for long-term outdoor applications.

Q: Can BW0-8028 be applied directly to metal?

The product data lists DTM use, meaning BW0-8028 can be applied directly to properly prepared metal surfaces. Surface cleanliness, profile, moisture and compatibility should still be verified before full application.

Q: What chemical resistance data is listed for BW0-8028?

The data sheet lists resistance to 40% H2SO4 or 10% HCl for 240 h, 40% NaOH for 240 h, 60 g/L salt for 240 h, 1000 h salt spray, engine oil for 240 h and 48 h water exposure.

Q: How can BW0-8028 be applied?

BW0-8028 can be applied by hand brush, roller, air spray at 0.3-0.5 MPa, or airless spray at 15-20 MPa, with recommended dry film thickness of 150-300 μm.

Q: What should buyers confirm before ordering BW0-8028?

Buyers should confirm substrate preparation, A/B weight ratio, pot life, application method, film thickness, recoat interval, chemical exposure, color requirement and the latest technical data sheet.
