Weld-On 2007 is a clear, water-thin, fast drying solvent. 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. Bonds made with Weld-On 2007 cure rapidly. Cure is effected by dissipation of the solvent. Initial bond takes 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. Joined materials will generally have the same rigidity or flexibility and other physical properties as prior to bonding.
Weld-On 2007 is formulated for rigid vinyl, and foamed PVC to themselves and to each other.
Weld-On 2007 is recommended 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.

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.
APPLICATION OF CEMENT: Weld-On 2007 can be applied by brush, spray, pump type oil cans, syringe, eye dropper, saturated felt pad and other devices. Cement may be applied to one or both surfaces.
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 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 clothes pins may be 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.
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 the effectiveness of the cement.

Safety and Environmental Precautions
Weld-On 2007 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 away from direct sunlight below 40º F – 110º F (5º C – 43º C). 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 Sheet and follow all precautions.
Contains Tetrahydrofuran (109-99-9) and Methyl Ethyl Ketone (78-93-3). 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.

Inhalation: If overcome with vapors, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call physician.
Eye Contact: Flush with plenty of water for 15 minutes and call a physician.
Skin Contact: Wash skin with plenty of soap and water for at least 15 minutes. If irritation develops, get medical attention.
Ingestion: If swallowed, give 1 or 2 glasses of water or milk. Do not induce vomiting. Contact physician or poison control center immediately.
