Installation

General Instructions
(If using cartridges, additional usage directions are available. See our information sheet labeled "Cartridge use directions".) See separate doweling, laminating, and patching instructions for more specific instructions. CSI format specifications are available.

Surface Preparation and Use
Use gloves, wear eye protection, and avoid skin contact. When grinding cured joints, wear a dust mask. Substrate to be bonded must be completely dry and dust free. Mix only the amount of epoxy which can be used in 10 minutes. Avoid stressing joint before complete cure of epoxy. Mask areas which must be kept free of epoxy. Clean tools with uncured epoxy using toluene or xylene. Use caution, these solvents are flammable and ensure local ventilation. Remove cured epoxy mechanically.

Mixing Instructions
All materials should be at or above 55° F. Combine the two ingredients at the following volume ratio: Two parts of A to one part B.

Temperature Dependency
Temperature will affect the working properties of the material. Every 15°F results in doubling the speed of cure. Therefore, at 90 °F set time is cut in half, at 60°F the set time is doubled. Do not use on substrate at a temperature below 55°F.

Coverage
Approximately 30 square feet per gallon when applied at 50 mils (1/16th of an inch). 231 cubic inches per gallon.

Availability

Packaging and Storage
Touchstone™ Clear Gel is available in quarts, gallons, 5 gallon pails and cartridges. Thickening powders are available for increasing viscosity. If Part A is exposed to below room temperature conditions for extended periods of time, it may crystallize, giving it a stiff, grainy consistency. The product must then be reconstituted before use by heating it up to 150°F. Stir until it becomes a homogeneous liquid.
