Revolutionary Elastomeric Polymer Composite Repairs, Resurfaces & Protects Flexible Components.

FLEXICLAD ER is a two component, 100% solids, trowelable polymer composite that has been specifically formulated to repair damaged flexible components such as conveyor belts, hoses, off-road tire sidewalls, etc.

FLEXICLAD ER is a very unique material that requires no primer, bonds to most rubber / flexible materials and cures at ambient temperatures – no heat is required. It is safe and simple to use and no special tools are needed. It can be used to create irregular flexible gaskets on distorted flange faces or to create a resilient bond for metal, wood, etc. It can also be used to seal / caulk heat exchanger water boxes to tube sheet faces or to seal joints in condensate pans, cooling tower pans, etc. FLEXICLAD ER is an indispensable addition to any maintenance engineer’s tool box.

FLEXICLAD ER is ideal for sealing joints and seams on machinery and equipment that are prone to vibration or movement – and wherever flexible repairs are required:

Physical Properties

Typical Values Test Method
Hardness - Shore D 15 ASTM D-2240
Elongation 175%   ASTM D-2370
Tensile Shear Adhesion
Steel 500 psi 35 kg/cm2 ASTM D-1002
Copper 500 psi 35 kg/cm2 ASTM D-1002
Both cases exhibited cohesive failure in the FLEXICLAD® ER itself.
Note: Adhesion to most rubber substrates when properly prepared is greater than the cohesive strength of the rubber substrate.
