Wood & Stone Company Akabond Flo-Gel 900 A & B is a solvent free, two-part, epoxy-based adhesive designed for use with all types of stone, including marble, granite, or engineered stone. It has been specially formulated to have a short cure time (workable within 1/2 hour) and excellent structural strength. It also features an easy one to one mix ratio. Flo-Gel 900 is ideal for use on small jobs or in a production line where speed is needed most.

 

Preparation: All surfaces must be dry and free of grease, oil, efflorescence and dust. Flo-Gel 900 will bond to moist surfaces. However, a dry surface will provide the best results. Because our products do not bond with polyethylene plastics, containers of this material are ideal for mixing purposes.

 

Application: If needed, Epoxy Coloring Paste, should be added to Resin “A” before mixing with Hardener “B”. The correct mixing ratio of Resin “A” to Hardener “B” is 1 to 1 by volume. Mix product carefully, scraping side of container often until a homogenous blend is achieved. Note, too much or too little hardener can significantly impact the bonding strength properties and final color of the product. Ambient temperature of the work area and the stone also affects curing time. Warmer temperatures speed the curing process, while lower temperatures will slow the curing process. Minimum application temperature recommended is 40°F (5°C). When adding pigment, these products should be mixed thoroughly until color is uniformly blended. At 77°F (25°C) the mixture is workable for about 3.5 to 5 minutes (see physical properties table). Flo-Gel 900 should not be worked once gelling has begun. Once the product becomes rubbery, excess material may be removed with a razor blade or chisel. When bonding stones, completely coat area to be bonded. Clamps and jigs should be used to ensure that a thin bond layer (less than 0.015 inches (0.4 mm)) is achieved, thereby providing the strongest, least visible bond. After curing, the stone piece may be further processed without damaging the material.
