A 2-part polyurethane resin designed for a fast repair, rebuilding and coating of rubber and metal components. This flexible rubber repair material is designed for emergency and permanent applications where high build, durability, elasticity, high abrasion and tear resistance are required. This very fast cold-curing 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 wear, impact and abrasion

Very fast cure for emergency repairs - repaired components back to service almost immediately

Cold-curing - no hot work involved

Packaged in individual pocket sized sachets for an easy application

Excellent adhesion to a wide variety of substrates including natural rubber, nitrile, neoprene, SBR (Styrene Butadiene Rubber), polyurethane, PVC, steel, copper and concrete

Outstanding mechanical strength

Reduces health and safety risks as it is solvent-free

Excellent chemical resistance to a wide variety of chemicals

Good electrical resistance

Outstanding elongation (up to 450%)

Protection against erosion and corrosion

Applications for Belzona 2311 (SR Elastomer) include:

Emergency repair of rubber components

Repair of rubber coatings on floating hoses to provide long-term abrasion resistance with very minimal downtime
