Description

System Three T-88 epoxy is a proven, tried-and-true structural adhesive suitable for wooden aircraft construction. FAA approved. T-88 is easy to use with a 1:1 mix ratio by volume, and it will effectively fill minor gaps between parts. It can also be combined with microballoons or cotton flocking when necessary. Once cured, T-88 is extremely strong and stable, and is not affected by most chemicals including water, oil, kerosene, diesel fuel, and aviation gasoline — but is NOT considered resistant to regular gasoline! It is also immune to fungus and rotting. T-88 will not damage foams including polystyrene (Styrofoam) and urethanes. T-88 will bond all woods as well as aluminum and glass. Epoxies will not adhere to Teflon (PTFE), polyethylene, polypropylene, nylon, mylar, PVC, acrylic (plexiglass) and polycarbonate (lexan) plastics. T-88 cures at temperatures down to 35 deg. F, and the cure time is heat-sensitive (Each 18 deg. F temperature increase halves the cure time.) Cured T-88 can be roughened to allow pieces to be bonded to it, if necessary. Includes one quart of resin and the appropriate amount of hardener. Priced per quart of resin (one 16 oz. bottle of Part A and one 16 oz. bottle of Part B).

USAGE NOTES: Like most epoxies, the working time for T-88 shortens with higher temperatures. T-88 is exothermic while curing. Like most epoxies, T-88 will self-heat when placed into a cup-like mixing container, causing it to set inside the cup very quickly. To prevent this, spread mixed resin out onto a flat surface (scrap cardboard works well) so that excess heat cannot build up in the mixture. Uncured resin and hardener can be cleaned up with denatured alcohol, MEK, or lacquer thinner. Unmixed components (Parts A or B) can also be cleaned up with white vinegar. Crystallized, milky or thickened epoxy resin or hardener can result from long-term storage or exposure to cold temperatures. In either case, the product can be restored to the normal consistency (with no damage to the product) either by warming the bottle for a FEW seconds in a microwave or (preferably) by placing the bottle into some hot water until the temperature is about 120 deg. F. Do not use resin or hardener that is crystallized or milky, as it will not mix properly… always use heat to return it to it’s proper state before mixing it. The hardener (Part B) may darken with age — this is normal and will have no effect on the strength of the cured material. T-88 epoxy generally will not “go bad,” even though crystallization or darkening may occur with time.
