DEVCON® Flexane® 80 Putty is a two-component, trowelable urethane compound designed for repairing, rebuilding, and lining process equipment subjected to wear, impact, abrasion, vibration, and thermal expansion/contraction. It cures at room temperature to form a medium-hard rubber (Shore A 87) with strong adhesion to a wide range of substrates including metal, concrete, rubber, wood, fiberglass, and rigid plastics.
Key Features & Benefits:
Easy trowel application, cures without heat.
Medium-hard, tough, flexible rubber finish.
Low shrinkage, excellent adhesion.
Bonds to diverse surfaces with suitable primers.
Provides wear resistance and vibration damping.
100% solids with high dielectric strength.
Shelf life: 2 years (sealed, 10–40°C storage).
Repair and rebuild conveyor belts.
Line process equipment to dampen impact and vibration.
Fill and line concrete control joints.
Cast flexible moulds, fixtures, and parts.
Potting and encapsulating components.
