System Three Epoxy Resin

System Three epoxy resin is their mainstay offering, and fits well into over 90% of all epoxy applications. It is a solvent-free unfilled medium-modulus system formulated for use with any of three hardeners (slow, medium, and fast used depending on pot life, set time, and temperature).

Mixed at a 2:1 ratio, System Three epoxy has excellent pot life and cure-time control. It is frequently used for new wooden boat construction and repair, gel coat blister repair, general fiberglass boat repair, coating, and general fiberglass work.

Combine this versatile resin with different fillers to create excellent adhesive, filleting and fairing compounds. Available in quart, gallon, 5 gallon, and 55 gallon quantities.

          I used this product on a canoe I built about ten years past and had good results on my first build.
          I have decided to build to a Kayak for my wife, I was hoping that the "system" was still available because when I find something that works I stick with it. Easy to Mix,easy to use for great results.

              Bought this epoxy resin to build a new hatch for the floor of my Center Console fishing boat. I used the medium hardener to allow a little more working time. The resin mixed well and dried to a super clear finish. I almost hate to cover the finish with any gelcoat it is so pretty and clear.

                      Not as hard as West System when cured, though this may be desirable in some applications where some flexibility is desired.

                      I've used System Three products for years with never a disappointment. I've used S3 to repair canoes, kayaks and small wood boats, house trim, antique newel post and a variety of woodworking projects. I weigh the resin and hardener with a postage scale and mix it in cheap paper bowels from the grocery store. I mix thoroughly for sixty seconds. Mix resin the same way every time and you'll have consistent results.

                        Comments about System Three Epoxy Resin:

                        I'm using System Three Epoxy to re-sheath an old plywood trimaran. I've used it with the fast and the medium hardener. In both cases it has provided a reliable layup - the working times quoted for the product are very accurate. Good adhesion to old wood and nice finish on the final layer. Mixed with a 50/50 mix of cabosil and microballoons makes an excellent, easily sanded filler and fairing material.

                        I've used West System and it is an excellent resin too. The flexibility of the System Three might be better on hulls where more flex is needed. I've used the West resin on some structural elements where a stiffer resin makes more sense (i.e. daggerboard trunk and bulkheads)
