Belzona 2141
Belzona 2141 (ACR-Fluid Elastomer) A 2-part polyurethane resin designed for the coating of metal and rubber components. This flexible rubber material is appropriate for coating extremely high localised pressure areas where abrasion, cavitation, erosion and corrosion resistance are required. This fluid material is easy to mix and apply without the need for specialist tools and it cures at room temperature eliminating the need for hot work.
Key benefits
- 01Outstanding protection against cavitation at ultra-high velocities (up to 115 knots with no damage)
- 02Excellent protection against abrasion, erosion and corrosion
- 03Application and cure at room temperature - no hot work involved
- 04Excellent adhesion to a wide variety of substrates including metals, alloys, natural and synthetic rubbers fibreglass and composites
- 05Can be applied using injection and forming techniques
- 06Excellent adhesion in long-term immersion - meets the ASTM D3623 requirements (90 day immersed cathodic disbondment test)
- 07Reduced health and safety risks as it is 100% solids
- 08High elongation - up to 530%
- 09Good chemical resistance to a wide variety of chemicals
Applications
- Coatings of cooling water pump impellers, wicket gates and stay vanes
- Anti-cavitation coating on Kaplan and Francis turbines
- Creation of a protective coating on ship propellers and Kort nozzles to provide long-term cavitation, erosion and corrosion protection
- Protective coating on shafts, valves and filters to prevent the effects of erosion and cavitation
