IPS 66 pint
WELD-ON 66 is formulated for bonding flexible or rigid vinyl (PVC) to itself or to urethane, leather, canvas, ABS,
foamed PVC, butyrate and wood.
WELD-ON 66 is recommended for fabricating or repairing flexible vinyl in numerous applications: pond liners,
shower pans, pool liners, moisture barriers, waterbeds, upholstery and wearing apparel. WELD-On 66 also bonds
urethane, leather and canvas to themselves and to wood, cardboard, Kydex, butyrate and ABS.
WELD-ON 66 is a clear, light bodied, fast drying solvent cement. It is used as a contact cement, providing instant,
high strength which will increase as solvent dissipates. The longer the open time (5 to 10 min) and with sufficient
assembly pressure, the greater the immediate strength will be. WELD-ON 66 may also be used on surfaces that
are wet to wet or wet to dry; but its special advantage is its high initial strength on contact. Whatever the bonding
technique used, it will provide high strength, long lasting, water resistant bonds under normal use, but some
yellowing may be expected.

DIRECTIONS FOR USE AND SPECIAL REQUIREMENTS
Clean and dry surfaces to be joined.
Coat each mating surface. Use a dauber or brush to apply an even coating with sufficient thickness for
Let each coating dry from 2 to 5 minutes.
Press firmly together. The longer the drying time, the greater the pressure required to effect a bond and the
higher the immediate strength will be.
For optimum strength on contact: After coating each mating surface, wait 10-15 minutes. Assemble
parts with strong pressure, e.g., a pinch roller or other line pressure over a hard surface. Even pliers have
been used successfully.
Long working time: Apply slightly thicker coatings to each substrate. Coatings may dry for 15 minutes or
more. As noted above, extra pressure will be needed to fuse the two surfaces together.
Light pressure assembly: Where it is not practical to apply strong pressure for contact fusion, apply a
normal coating to each mating surface. Wait _ to 1 minute and apply as much pressure as possible.
Bonding thin PVC (less than 15 mil): Apply a very thin coat rapidly, use a brush to attain a thin coating,
or apply a normal coating, then thin it down by scrapping an edge of a card over it, removing the excess
content. Let dry for at least 2 minutes and then assemble with strong pressure.
Bonding to porous surfaces: Apply at least 2 coats where strike-in or soak-in appear to starve the
surface of porous materials---wood, foam, etc.
Three years expectancy in tightly-sealed containers. Stability of the product is limited by the permanence of the
container and the evaporation of the solvent when container is open. Evaporation of solvent will cause the
cement to thicken and reduce its effectiveness.

SAFETY AND ENVIRONMENTAL PRECAUTIONS
Weld-On 66 is a flammable, fast evaporating, solvent cement. It is considered a hazardous material. In
conformance with the Federal Hazardous Substances Labeling Act, the following hazards and precautions are
given. Purchasers who may re-package this product must also conform to all local, state and federal labeling,
safety and other regulations.
DANGER! – EXTREMELY FLAMMABLE – VAPOR HARMFUL –
MAY BE HARMFUL IF SWALLOWED – MAY IRRITATE SKIN OR EYES
Keep out of reach of children. Do not take internally. Keep away from heat, spark, open flame and other sources
of ignition. Keep container closed when not in use. Store in the shade between 40ºF and 80ºF. Use only with
adequate ventilation. Avoid breathing of vapors. Atmospheric levels should be maintained below established
exposure limit values contained in Section II and VIII of the Material Safety Data Sheet. If airborne concentrations
exceed those limits, use of a NIOSH-approved organic vapor cartridge respirator with full face-piece is
recommended. The effectiveness of an air-purifying respirator is limited. Use it only for a single short-term
exposure. For emergency and other conditions where short-term exposure guidelines may be exceeded, use an
approved positive pressure self-contained breathing apparatus. Do not smoke, eat or drink while working with this
product. Avoid contact with skin, eyes and clothing. May cause eye injury. Protective equipment such as gloves,
safety goggles and impervious apron should be used. Carefully read Material Safety Data Sheets and follow all
precautions. Contains Methyl Ethyl Ketone (78-93-3) and Tetrahydrofuran (109-99-9). Do not use this product for
other than intended use.
"Title III Section 313 Supplier Notification": This product contains toxic chemicals subject to the reporting
requirements of Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 and of
40CFR372. This information must be included in all MSDS’s that are copied and distributed for this material.
Inhalation: If ill effects from inhalation, remove to fresh air. If not breathing, give artificial respiration. If breathing
is difficult, give oxygen. Call physician.
Eye or Skin Contact: Flush with plenty of water for 15 minutes. If irritation persists, get medical attention.
Ingestion: If swallowed, do not induce vomiting. Contact physician immediately.
Every batch of this cement is checked to assure that consistent quality is maintained. An infrared absorption
curve is recorded for each batch to ensure that this cement is properly formulated. Samples are taken from all
batches and kept for a period of at least one year. A batch identification code is stamped on each can.
