Overview of Belzona 2111
A 2-part polyurethane resin designed for the repair, rebuilding and coating of rubber and metal components. This flexible rubber repair material is appropriate for applications where high build, durability, elasticity, high abrasion and tear resistance are required. This 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
Cures at room temperature with no hot work or vulcanisation
Bonds to natural rubber, nitrile, neoprene, SBR, polyurethane, PVC, steel, copper and concrete
High tensile and tear strength for demanding mechanical environments
Outstanding resistance to a wide range of chemicals
Small or large areas treated in one operation with no joint lines
