We are a professional manufacturer with years of expertise in the industrial coatings field. Today, we’ll discuss a heavy-duty protective coating—acrylic urethane paint. Whether it’s factory equipment, steel bridges, or outdoor construction machinery, this coating plays a crucial role. This article breaks down its features, applications, and application methods in simple terms.
1. What is Acrylic Urethane Paint?
Think of it as a “protective armor” for metal surfaces.
Acrylic urethane paint is a two-component coating (base + curing agent). When mixed, a chemical reaction occurs, forming a dense, tough film. Its key advantage is exceptional weather resistance—whether under intense sunlight, heavy rain, or freezing temperatures, it maintains color and gloss for years without chalking or cracking.
2. Top 5 Benefits of Acrylic Urethane Paint
✔ Superior Weather Resistance – While ordinary paints fade or degrade in 1-2 years outdoors, high-performance acrylic urethane paint lasts 5-10 years (depending on conditions). Its chemical structure resists UV rays, acid rain, and salt spray corrosion, making it ideal for coastal areas, chemical plants, and harsh environments.
✔ Abrasion & Impact Resistance – Forklift collisions, gravel scratches? No problem. Its hard yet flexible film protects metal surfaces from scratches and deformation.
✔ Low VOC, Eco-Friendly & Safer – Unlike traditional solvent-based paints with strong odors, water-based acrylic urethane paint (or low-VOC acrylic urethane paint) meets environmental regulations, ensuring safer application for workers.
✔ Aesthetic & Long-Lasting Gloss – Available in matte, semi-gloss, and high-gloss finishes, with rich, uniform colors that resist yellowing—perfect for equipment or structures requiring both durability and appearance.
3. Where is Acrylic Urethane Paint Used? (Best Applications)
- Steel Structures – Bridges, stadiums, industrial plants (best for rust & corrosion protection).
- Construction Machinery – Excavators, cranes (long-term outdoor exposure demands UV-resistant coatings).
- Automotive Refinishing – Trucks, buses (excellent color matching & durability).
- Chemical Storage Tanks – Resists acid/alkali corrosion, extending equipment lifespan.
| Indústria | Common Uses | Why It’s Ideal |
| Construção | Bridges, steel beams, stadiums | Rust-proof, weather-resistant |
| Equipamento industrial | Cranes, excavators, pipelines | Abrasion & chemical resistance |
| Automotive | Truck refinishing, trailers | UV protection & color retention |
| Marine | Ship hulls, offshore platforms | Saltwater corrosion resistance |
| Architectural | Metal roofs, facades | Aesthetic + long-lasting finish |
Real Case Study:
A coastal wind turbine tower project initially used standard paint, which rusted within 2 years due to high salt spray. After switching to high-performance acrylic urethane paint, the coating remained intact for 5+ years, reducing maintenance costs by 60%.
4. How to Apply Acrylic Urethane Paint (Step-by-Step Guide)
Key Rule: Clean surface, precise mixing, thin & multiple coats!
① Surface Preparation
- Metal must be fully derusted (recommended: sandblasting to Sa2.5 grade).
- Remove grease with solvents.
- Illustration prompt: Worker sandblasting metal, rust and old paint peeling off.
② Mixing the Coating
- Combine base & curing agent at the specified ratio (common: 10:1).
- Stir well, then let it sit for 10 mins (induction time).
- ⚠ Pot life: 4 hours (use before it gels).
③ Spraying/Brushing
- Spraying (best for uniformity): Use a 1.5-2.0mm nozzle, 0.4-0.6 MPa pressure.
- Brushing: Apply in one direction to avoid bubbles.
④ Drying Time
- Touch-dry: 2 hrs | Hard-dry: 24 hrs | Full cure: 7 days (at 25°C).
- Longer drying needed in cold weather.
⑤ Repair Tips
- Sand damaged areas, apply thin layers, and blend edges for smooth transitions.
