WELD-ON 2354

                                                          ACRYLONITRILE-BUTADIENE-STYRENE (ABS)









SUBSTRATE RECOMMENDATIONS

WELD-ON 2354 is formulated for bonding ABS, styrene (general purpose high impact), acrylics and poly-

carbonates to themselves. It should not be used for joining dissimilar materials such as: ABS to styrene, ABS to

acrylics, ABS to PVC or PVC to styrene.



BONDING RECOMMENDATIONS

WELD-ON 2354 is recommended for joining ABS, styrene and acrylics to themselves where a water-thin cement

is desired. It is suitable and used on both large assemblies and small delicate assemblies. These include a

wide variety of items: signs, large displays, lighting fixtures, housewares, electrical assemblies, decorator items

and many other fabrications.



GENERAL DESCRIPTION

WELD-ON is a clear, water-thin, fast drying solvent cement. It may be applied by brush, syringe, spray, and

most any other method. It forms bonds by the softening and fusion of the two surfaces in contact. Cure is

affected by dissipation of the solvent and cures rapidly. Initial bonds take place within a few minutes and is often

of sufficient strength to permit handling of the bonded item. Relatively high strength is reached in 24 to 48

hours, and continues to increase for a number of weeks. The joined material will generally have the same

rigidity or flexibility and other physical properties as prior to bonding.

DIRECTIONS FOR USE

� JOINT PREPARATION: Parts to be joined should fit without forcing. Surfaces should be clean and smooth. A

  good machine finish or sanding with 200-400 grit sandpaper should be satisfactory. Surfaces “as molded or

  extruded� may not require additional preparation.

� ASSEMBLY OF PARTS: Assemble while parts are still wet. If cement is applied to one surface, let the two

  surfaces be in gentle contact for a few seconds to allow the cement to soften the dry surface. Then press

  parts together in firm contact. If both of the parts have been coated, they may be brought firmly together

  immediately. The application of pressure of 2 to 10 pounds per square inch should materially increase bond

  strength. Spring-loaded clothespins may be very suitable as clamps. The length of time required for clamp or

  jig pressure will vary. A few hours may be required for difficult joints and a few minutes for parts that fit well

  and have modest load requirements.

� CAPILLARY METHOD: Parts are placed lightly together and cement is applied to the edge of the joint with

  brush, eyedropper, or syringe. By capillary action, the cement will flow a considerable distance between two

  such surfaces. After a few seconds are allowed for the cement to soften the surfaces, the parts may be

  pressed together firmly. Where surfaces are very smooth and fit well together, it is sometimes possible to

  obtain good joints without additional clamping pressure. However, it may be best in most cases to maintain

  clamp pressure as outlined above.

� APPLICATION OF CEMENT: WELD-ON 2354 can be applied by brush, spray, pump type oil cans, syringe,

   eye dropper, saturated felt pad and other devices.



SHELF LIFE

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.

SAFETY AND ENVIRONMENTAL PRECAUTIONS

Weld-On 2354 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.

                              CAUTION! � 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 below 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.
