Known backups / known substitutes
- Devcon Flexane 80 Putty: A trowelable urethane with a longer pot life (20 minutes) and slightly different properties (e.g., 87 Shore A hardness, 300% elongation, 1700 psi tensile strength).- Devcon Flexane 80 Liquid: A medium-viscosity castable urethane.- Devcon Flexane 94 Liquid: A more rigid liquid urethane.- Devcon Flexane High Performance Putty: Another rubber-like urethane compound for wear, abrasion, and noise reduction.- Devcon Flexane Fast Cure Liquid.
Comparison Note
DEVCON Flexane Fast Cure Putty [4-1] is distinguished by its rapid cure time and convenient cartridge dispensing system, offering an 8-minute pot life and functional cure in 3 hours, making it ideal for quick repairs where minimal downtime is critical. In contrast, products like Devcon Flexane 80 Putty provide a longer working time (20 minutes) and a full cure in 12 hours, which may be preferred for larger applications requiring more intricate shaping or extended application times. The Fast Cure Putty also offers superior flexibility, elongation, and adhesion to rubber compared to some other Flexane formulations.
