0.86 Quart West System 205-B Fast Hardener

This item can only be shipped UPS GROUND. Choose 205 Fast Hardener when Cold-Weather Bonding 205 Fast Hardener is formulated to cure well at temperatures as low as 40°F (4°C). This will require an extended cure time before removing clamps or sanding. For best results in cold weather, warm 105 Resin and 205 Fast Hardener before using. Cold temperatures increase the viscosity of the epoxy, making it more difficult to dispense, mix and apply. Warming resin and hardener reduces their viscosity so they flow through dispensing pumps better, cling less to your mixing equipment, and blend more easily for thorough mixing. A warmer, lower-viscosity mixture will flow more smoothly during application and penetrate porous surfaces more readily. Always dispense 105 Resin and 205 Fast Hardener at the proper mixing ratio. Altering the amount of hardener will seriously compromise the epoxy’s ultimate strength. WEST SYSTEM 300 Mini Pumps are calibrated to dispense the correct resin-to-hardener ra
