BELZONA 1121

Belzona 1121 (Super XL-Metal)

Belzona 1121 (Super XL-Metal) is a high-performance, two-component, epoxy-based repair composite designed for extended working life and high precision in applications requiring durable and reliable metal repair solutions. It is particularly suitable for larger-scale repairs and intricate reshaping tasks, thanks to its long working time and excellent adhesion.

Key Features

1. Extended Working Time:
   • Allows for more complex and larger-scale applications without rushing the process.
2. High Strength and Durability:
   • Excellent resistance to wear, impact, and mechanical stress.
3. Exceptional Adhesion:
   • Bonds strongly to a variety of substrates, including metals, ceramics, and composites.
4. Non-Shrinking:
   • Retains dimensional stability during curing.
5. Machinable After Curing:
   • Can be drilled, tapped, or machined for precise finishing.
6. Temperature Resistance:
   • Operates in temperatures up to 120°C (248°F) continuously and 150°C (302°F) intermittently.

Applications

• Metal Repairs:
  • Repair cracks, holes, and worn surfaces on machinery, equipment, and structural components.
• Rebuilding Components:
  • Reshape damaged pump casings, impellers, flanges, and more.
• Corrosion Protection:
  • Protects surfaces from chemical and environmental degradation.
• Sealing and Bonding:
  • Ideal for sealing leaks and bonding dissimilar materials.

How to Use

1. Surface Preparation:
   • Thoroughly clean the surface to remove contaminants like grease, oil, and loose material. Abrade the surface for better adhesion.
2. Mixing:
   • Combine the resin (Part A) and hardener (Part B) in the recommended ratio until a uniform color is achieved.
3. Application:
   • Apply the mixture using a spatula or brush, ensuring it adheres well to the prepared surface.
4. Curing:
   • Allow the material to cure at room temperature. Full mechanical properties are typically achieved within 24-48 hours.
