NOTE:
Do not add solvent to glue in an attempt to extend its pot life.
( 3 ) The recommended quantity of glue to mix at one time is approximately 160 cc
(150 cc glue + 7.5 cc accelerator = 157.5 cc). Keep the glue container covered
after mixing to extend the useful life. The accelerator has a useful life of only 24
hours after the bottle is opened. Do not reuse a glue container without
cleaning it thoroughly. Always mix glue in a fresh container.
NOTE:
Do not attempt to use glue that has passed the expiration date marked on the
container. Store glue at a temperature between 40 F and 80 F. Before mixing in
the accelerator, stir the glue in the container to mix components that settle to the
bottom of the container. Do not attempt to use glue that was mixed more than 60
minutes earlier. Do not use accelerator from bottles which were opened more
than 24 hours earlier. Bonds made with old glue will not hold. All old glue must be
scuffed off both pieces and the surfaces treated with solvent and reglued.
c.
Application of Solvent. After the surfaces to be glued have been scuffed (paragraph F-3),
they must be treated with solvent at 5 minutes intervals: three applications 5 minutes apart for MEK; two
applications 5 minutes apart for toluene. The correct solvent for the materials and glue must be used.
Toluene is the solvent used to treat hypalon neoprene fabrics ( buoyancy tubes) and wood, and MEK is
the solvent used to treat PVC coated fabrics such as the strongan (rollup floor, carrying bag, keel) and the
molded PVC parts such as bow handles and D-ring pads (except towing D-rings).
Use caution when working with toluene. Toluene is a flammable and
poisonous solvent. Do not use near sparks or flame. Use outdoors or
provide adequate ventilation. Use in a confined space can cause loss of
consciousness and in extreme concentrations, death. Wipe up all spills
immediately. Remove toluene soaked towels from the work area to reduce
the concentration of toluene in the air and prevent fire. Minimize contact
toluene with the skin. Never leave toluene soaked towels on boat fabric.
