System Three T88 epoxy is a high performance structural adhesive resin for wood, metal, concrete, marble and most rigid surfaces. This waterproof, non-brittle, two-part epoxy adhesive is designed to provide superior results under adverse conditions.

T88 may be used without modification in normally fitted joints, and will cure in any thickness without shrinkage. It is a clear amber and becomes virtually invisible when varnished. This epoxy exhibits outstanding adhesion and permanence on a wide variety of materials, and is endorsed by leading designers, builders, and organizations.

Working time is one hour, Tack-free in 4-6 hours. Tensile strength 7,000 psi. T88 is often used as a very strong woodworking glue.

    I have used T88 for about six years and it is a good product. It can be messy but I've figured out how to control it. It can be difficult to pump especially when cold so I have a solution for that and to keep it from dripping during storage, I solved that also.

    Strong adhesive

    Avery good adhesive. Has to be mixed 1 to 1. very thick hardener and resin, so it's difficult to mix.

    Use this product to turn 3" hardwood flooring into stair treads. kind of an unconventional idea but this product helped bring it to life. The look great.

    Great Glue

    Bottom Line for me is, the wood breaks before the glue joint. I also find a loose joint works the best for me using T-88.

    Testing Proof To Myself

    5

    While planning my 21 ft Dory I ran some destructive test using Pine 2x4s and 1/2" Plywood. I tried 3 different glues:1. T-88 Epoxy2. Gorilla Glue3. Yellow Water Proof Wood GlueThe 1st test was with the 2 x 4 on edge with 4" of glue and held with 2 screws to the plywood. All three samples were precoated so as not to have dry joints and recoated after 5 minutes. After 24 hours the samples were broken.1. The T-88 Epoxy Sample took wood from both the plywood and 2 x 4s. But only about 1/8" deep.2. The Gorilla Glue also took some wood but less then the Epoxy.3. The Yellow Wood Glue had only minor amounts of wood where broken.The 2nd test was made only with T-88 Epoxy as it was the clear winner of test #1. With this 2nd test I once again made samples using 2 x 4s and 1/2" plywood.1. Tight joint as in Test #1 with T-88.2. Loose joint with one end touching and the other end 1/8" loose but fully filled with glue.3. The 3rd sample was also loose in the same way but I added some 1/32" chopped fiberglass to the epoxy. ( 3 TBS for ¼ cup of epoxy) Sorry for the cooking measurements.4. The 4th sample was also made with the glass filled epoxy, but the joint was tight.After 24 hours I broke the parts.1. The tight joint with T-88 took a small amount of wood and was about the same as the first test results.2. The 2nd sample took a little more wood.3. The 3rd sample took wood about 1" deep in the 2 x 4 and ripped the plywood.4. The 4th sample also took wood but about ½ as much as sample #3.OK, so the clear winner was a loose joint with glass filled T-88. (So much for wood class and making a good tight glue joint. Lol)My boat plans called for face to face gluing of 2 x 4s and so I glued some samples using 18" long boards glued at one end forming a 90 deg part. I made 2 samples of each.1. Sample #1 was glued using glass filled T-88 and held with two 3" deck screws.2. Sample #2 was the same except I drilled a hole 3/8" diameter 1/4" inch deep at each screw. (Glue Faces) I filled these holes with glass filled epoxy and reclamped with the screws.After 24 hours I removed the screws and broke the samples using a hyd press. All 4 samples were very strong but the samples with the filled 3/8" holes took a lot more force to break. Also these 2 samples failed by breaking deep into the board.After getting these results I have started my boat and made all of my joints with glass filled T-88. I now have it ready to apply the plywood.Bottom line is, I trust T-88 Epoxy. No I don't work for System Three.

    Yes

    great for bent wood laminations

    4

    great for glueing up laminations when bending wood using this method. no creep even after years.long working time is a big plus when setting laminated piece into forms.squeeze out can be a problem because of glue viscosity.

    I used this product in several traditional wood boat construction, specially in gluing 1/16th mohagany, on spanish cedar in control temperature.It become difficult to glue when the temperature dropped below 60 degrees.
