TotalBoat High Performance Epoxy Resin and High Performance Non-Blushing Hardeners can be poured (to measure by weight or volume), or dispensed in exact measure using TotalBoat 2:1 Epoxy Pumps. Our are intended for use only with TotalBoat High Performance Epoxy Resin and Hardener containers, and they will not fit other marine 2:1 epoxy resin and hardener containers.
Which TotalBoat High Performance Hardener Do I Need for My Project?
High Performance Fast Hardener – Use High Performance Fast Hardener for the fastest cure and shortest working time at room temperature, or for an overnight cure in low temperatures (minimum 55°F).
High Performance Medium Hardener – Use High Performance Medium Hardener for most common applications, or for an overnight cure at room temperature (77°F).
High Performance Slow Hardener – Use High Performance Slow Hardener for extended working time and cure time at room temperature, or when working in warmer temperature conditions. If you are new at working with epoxy resin, the slow speed hardener will give you more working time, which you may find helpful.
Even better, you can customize pot life and cure time further by combining the different hardeners with each other. Just remember to always maintain the proper ratio of 2 parts resin to 1 part hardener by volume.
High Performance Slow Hardener Details
- For use with TotalBoat only.
- Provides the longest pot life and the slowest cure time at room temperature.
- Can be combined with other TotalBoat 2:1 Hardeners to customize or fine-tune working properties and cure time.
- Color: Clear
- Sizes: Group Size A – Pint (15.2 fl. oz.), Group Size B – Half Gallon (63.8 fl. oz.), Group Size C – Gallon (127.7 fl. oz.)
- Slow hardener is also available in a 26.1 gallon container, for use with drums of High Performance Resin. Please contact us for pricing.
- Note: Hardener sizes correspond to group sizes of TotalBoat High Performance 2:1 Epoxy Resin (sold separately).

**NOTE: For 2:1 Slow Hardener maximum pour depth: Helping to dissipate heat from the cure will generally promote a more clear, smooth surface. If heat is not allowed to dissipate sufficiently from a mold or casting, it is still possible for pours, even with these guidelines, to generate enough heat to leave an imperfect surface or a slight yellow cast in the cured product.
