TAP Marine Grade Epoxy System

A premium epoxy system with 100% solids, no solvents, and very simple mix ratios. TAP Marine Grade Epoxy is perhaps the safest epoxy on the market. Its low toxicity allows us to ship it without special restrictions. Blend the A-Side of the System, TAP 314 Resin, with your choice of three different hardeners (see below) to achieve different cure rates and physical properties. Currently, the majority of watercraft are made of polyester resins, which are excellent for initial construction. For repairs, however, they lack the tenacious adhesive properties of Marine Grade Epoxy. This epoxy is a stronger adhesive and forms a superior bond to polyester and many other materials. Polyester will shrink during cure, creating stress at the point of repair. Marine Grade has no significant shrinkage during cure. TAP 314 Resin is virtually transparent with a very low viscosity. All items are available in 5-gallon sizes by phone order only: (888) 827-7330 Mon-Fri 9 am to 5 pm (PST).

B-Side Hardener • 102 • Fast
Fast cure, 2.5 to 3 hours. 14 to 19 minute pot-life. Cures at a low temperature, down to 40ºF. The mix ratio is 4 to 1. Use for adhesive, laminating, and fairing. Excellent fuel and solvent resistance.

B-Side Hardener • 109 • Medium
Medium cure, 5 to 5.5 hours. 30 to 35 minute pot-life. Clearest of the hardeners for a transparent finish. The mix ratio is 4 to 1. Use for adhesive, laminating, clear finishes. This hardener is the most sensitive to temperature. It should be cured at no lower than 77ºF. Ideal cure temperature is 80º-85ºF. Lower temperatures will produce blushing and potential incomplete cure.

B-Side Hardener • 143 • Slow
Slow cure, 6 to 6.5 hours. 30 to 35 minute pot-life. Minimum temperature use: 40ºF. Cures at either a summer or winter temperature. Very low viscosity. Excellent wet out, chemical and impact resistance. Mix ratio is 2 to 1. Use for adhesive, laminating, and penetrating.
