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:

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 a wide variety of substrates including metals, alloys, natural and synthetic rubbers fibreglass and composites

Can be applied using injection and forming techniques

Excellent adhesion in long-term immersion - meets the ASTM D3623 requirements (90 day immersed cathodic disbondment test)

Reduced health and safety risks as it is solvent-free

High elongation - up to 530%

Good chemical resistance to a wide variety of chemicals

Applications for Belzona 2141 (ACR-Fluid Elastomer) include:

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

Key technical data:
