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.
Warranty
This product’s warranty is limited to replacement of defective
material and freight charges to destination only. Bonstone Materials
Corp. is not responsible for consequential damages.
Maintenance
This product is designed for application in areas inaccessible to maintenance
procedures. Some powerful etching compounds, especially those containing
hydrofluoric acid, may degrade the material.
