Belzona 2141

ACR-Fluid Elastomer — Flexible cavitation and abrasion resistant polyurethane elastomer for the coating of metal and rubber components.

A 2-part polyurethane resin engineered for ultra-high velocity cavitation environments. Withstands cavitation at speeds up to 115 knots with no damage. Meets ASTM D3623 long-term immersion requirements — ideal for marine and hydraulic turbine applications. 530% elongation, 100% solids, cold-cure.

Belzona 2141 (ACR-Fluid Elastomer)

Product Description

A 2-part polyurethane resin designed for the coating of metal and rubber components in extremely high localised pressure areas where abrasion, cavitation, erosion and corrosion resistance are required. This fluid material is easy to mix and apply without specialist tools — cures at room temperature, eliminating the need for hot work.

Key Benefits

  • Outstanding protection against cavitation at ultra-high velocities — up to 115 knots with no damage
  • Excellent protection against abrasion, erosion and corrosion
  • Application and cure at room temperature — no hot work involved
  • Excellent adhesion to metals, alloys, natural and synthetic rubbers, fibreglass and composites
  • Can be applied using injection and forming techniques
  • Meets ASTM D3623 requirements — 90-day immersed cathodic disbondment test
  • Reduced health and safety risks — 100% solids
  • High elongation — up to 530%
  • Good 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
  • Protective coating on ship propellers and Kort nozzles for long-term cavitation, erosion and corrosion protection
  • Protective coating on shafts, valves and filters to prevent the effects of erosion and cavitation

* All products are subject to regional restrictions.

Approvals

CCS
China Classification Society Approved for marine applications requiring cavitation and corrosion resistance on ship hulls and propulsion systems.
