Premium, easy-to-use, low-viscosity, clear epoxy resin system in a convenient kit

Use TotalBoat High Performance Epoxy Resin for a moisture-resistant cure that’s more clear and slightly more flexible than traditional 5:1 epoxy resin systems. Its greater elasticity is especially ideal for building and repairing wooden boats prone to flexing during use or with fluctuations in temperature and humidity.

The calibrated pumps (included) and the simple 2:1 mix ratio of 2 parts resin to 1 part hardener makes it easy to get a perfect cure every time. If you use High Performance Epoxy frequently, our TotalBoat High Performance Epoxy Metering Pump Dispenser is pre-calibrated to the exact 2:1 ratio. So whether you need a little, or a lot, you’ll get the right ratio every time, without messes, spills, or waste.

This versatile High Performance Resin Kit system can be used for so many different projects. Use unfilled for laminating, hand layups, coating, and vacuum bagging. Or, add TotalBoat fillers for a strong adhesive, filleting material, or fairing compound. So many capabilities at such a great value.

Cures to a high-gloss, ultra-clear finish—with no blush to scrub off between coats

Its exceptionally clear, level finish is perfect for clear coating projects like showcasing carbon fiber’s cool weave patterns, or for emphasizing wood’s natural color, grain, and beauty. And, because there’s no amine blush, you won’t waste time on messy washdowns between coats, or worry whether you removed every trace of surface blush, so you can apply the next coat knowing it’ll cure properly.

Three hardener speeds let you control working properties and cure times

With our High Performance Epoxy Resin, whether your goal is to buy more time or speed up the process, we make the choice easy by offering Fast, Medium, and Slow High Performance Hardeners that let you modify working properties and cure time to your advantage.

If you want the fastest cure and shortest pot life, or if you’re working in cooler temperatures, use the High Performance Fast Hardener. For most common applications, use the High Performance Medium Hardener. If you’re working in warm conditions, or you need a longer working time, use the High Performance Slow Hardener. Likewise if you’re new to using epoxy resin, you may find the extended pot life and cure time helpful.

All of its “lows” are its high points

  • Low 2:1 mix ratio makes it very easy to measure precisely for a proper mix and a reliable cure.
  • Low viscosity flows easily to saturate the fibers in composite fabrics for better hand layups and vacuum bagging projects. Excellent thin-film characteristics provide smooth flow-out and self-leveling ideal for coating and laminating.
  • Low drip properties ensure smooth and strong coating, laminating, and bonding, and it cures with very low shrinkage.
  • Low VOC content and low odor make it more suitable for shop or garage use where indoor air quality is especially important.

Which TotalBoat High Performance Kit Speed Should I Choose?

High Performance Fast Kit – Use the High Performance Fast Kit 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 Kit – Use the High Performance Medium Kit for most common applications, or for an overnight cure at room temperature (77°F).

High Performance Slow Kit – Use the High Performance Slow Kit for extended working time and cure time at room temperature, or when working in warmer temperature conditions.

Frequently Asked Questions

What is the difference between High Performance and Traditional 5:1 epoxy resin kits?

High Performance Epoxy is clear and more flexible when cured than the Traditional 5:1 Epoxy system, which has higher tensile strength and stiffness. Both systems are used for boat building and repair, composite laminating, bonding, fairing and filleting, but because of its clear color, the High Performance system is also ideal for clear coating applications in wooden boat builds, shallow castings in epoxy river tables, woodworking and art projects.

Each system has its own set of hardeners: High Performance has fast, medium, and slow hardener; the 5:1 system has fast and slow hardeners. Finally, when the 5:1 system cures, the surface is coated with amine blush, a waxy byproduct that must be washed off before additional coatings are applied. The High Performance Epoxy system is practically blush-free.

Which TotalBoat High Performance Hardener should I use?

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).

Use High Performance Medium Hardener for most common applications, or for an overnight cure at room temperature (77°F).

Use High Performance Slow Hardener for extended working time and cure time at room temperature, or when working in warmer temperature conditions.

Does this epoxy dry clear?

When High Performance Epoxy Resin is paired with its Slow or Medium Hardener, the resulting cured epoxy is extremely clear; when paired with its Fast Hardener, it may have a slight amber tone, but in most applications, this is not noticeable. Even if there is a tiny bit of amber color in the hardener, it’s minimized once the resin and hardener are mixed. In thin film applications, such as laminations, there won’t be enough material to show any amber tone. However, if absolute clarity is required for a specific application, Slow or Medium Hardener might be a more suitable choice.

What does “blush-free” mean?

Amine blush is a waxy substance that forms on the surface as epoxy cures. It can interfere with the adhesion of additional coatings, so it must be removed gently with warm water and a Scotch-Brite pad. Blush is present in all epoxies but its content in clear epoxy is extremely low. Even so, it’s possible small pockets of blush can collect on the surface so it’s considered best practice to wash the surface with warm water and a Scotch-Brite pad prior to sanding.

Is High Performance Epoxy Resin UV resistant?

Most epoxies have poor UV resistance and must be coated with varnish, a polyurethane clear coat, or other UV stable coating. 

Is High Performance Epoxy Resin food safe after it’s cured?

This epoxy is BPA-free, and is considered safe for indirect contact with food, once cured.

How do I apply High Performance Epoxy?

Application method varies by project type. You can apply using a spreader, syringe, or roller. For shallow casting, pour at a maximum thickness of 1/8th – 1/4th inch depth, per layer. Pour multiple, shallow layers, for best results.

Can I use High Performance Epoxy in cold weather?

Yes, but cold temperatures make the viscosity of resin and hardeners increase and may require more force to pump thicker materials. Excessive force on either one of the plunger heads may also cause the pumps to break. Dispensing material at 60-70°F is recommended for optimal pump performance.

What are the ideal working conditions?

Epoxy is very sensitive to application temperatures. The minimum recommended temperature for all hardeners is 55°F. The recommended temperature for dispensing via pump is 60-70°F.

What is the working time of the High Performance Epoxy?

10 minutes for fast hardener, 25 minutes for medium hardener, and 40 minutes for slow hardener.

What is the recoat time of this resin system?

You can recoat once it tacks up a little, about 25 minutes at 77 degrees.

What is the mix ratio of this epoxy by weight?

When using Fast Hardener: 100A:46B. When using Medium Hardener: 100A:45B. When using Slow Hardener: 100A:45B. The first number is the amount of epoxy resin; the second number is the amount of hardener.

Do I need to sand epoxy between coats?

Light sanding is recommended, followed by an oil-free solvent wipe or a clean cloth moistened with either isopropyl alcohol or plain water to remove dust.

How should I prepare this epoxy for primer after sanding?

After the epoxy has cured, wash with warm water just in case there is any amine blush, sand smooth and wipe the surface with a clean, lint-free rag dampened with acetone or denatured alcohol.

Will epoxy still cure if mixed at an incorrect ratio?

No, unlike polyester resin, epoxies require a very specific resin to hardener ratio in order to cure properly. You will need to remove the epoxy and start over. Solvents like acetone may be used to remove the uncured resin.

Can I leave the pumps in the resin containers?

Yes, you can leave the pumps on in the resin and hardener containers when not in use for a few weeks, but for longer-term storage, we recommend that you pull the pumps out, clean them, and put the original caps on the resin and hardener containers.

Can this epoxy resin be thinned?

We don’t recommend thinning High Performance Epoxy with any type of solvent, because solvents can drastically change the properties of the epoxy. Heating the resin slightly is the best way to thin it because it makes the epoxy more workable, without changing the chemical composition. More information on thinning epoxy can be found here.

How many square feet will one-gallon of mixed epoxy cover?

When poured as a coating or for sealing a surface, one gallon of mixed epoxy yields approximately 25.6 square feet at 1/16" thickness, 12.8 square feet at 1/8" thickness, and 6.4 square feet at 1/4" thickness. More information on epoxy coverage can be found here.

Is this resin compatible with fillers?

Yes, this epoxy system can be used with various fillers to thicken it for bonding, fairing, filling, and filleting. It can be mixed with fillers such as colloidal silica (also known as silica thickener), milled glass fiber, wood flour, or microballoons. Add fillers after epoxy resin and hardener are mixed thoroughly. More information on epoxy fillers can be found here.
