1. Product Overview

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).


2. Applications

  • 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.
