Description

General Description

Weld-On 45 is a fast curing, two-component, low VOC, reactive adhesive. When mixed and applied, it polymerizes at room temperature to form high strength bonds within an hour. The adhesive has excellent corrosion resistance, good gap-filling capabilities, weatherability and outstanding impact strength at low and high temperatures. Once cured, the adhesive will withstand a temperature range of -20° F (-29° C) to 200° F (93° C). The elongation will remain the same even at high temperatures up to 200° F (93° C). UL 746C (aluminum, fiberglass).

Substrate Recommendations

Weld-On 45 is formulated for bonding a wide variety of metals, plastics and many other substrates.

Bonding Recommendations

Weld-On 45 is recommended for a variety of applications and industries including sign assembly and other fabrication and manufacturing uses where high bond strength and environmental resistance is required. This adhesive is especially suitable for bonding aluminum, CRS, brass, copper, galvanized steel and other metals. Excellent adhesion is also obtained on plastics such as PVC, polycarbonate, ABS, acrylic and PETG.

Directions

Directions for Use

Weld-On 45 is packaged in a twin-syringe cartridge that dispenses product in a 4:1 mix ratio. The cartridge must be inserted in the dispensing gun and the mixing tip attached prior to dispensing.

  • Before inserting the cartridge in the dispensing gun, open cartridge valve and clean obstructions from cartridge nose and valve opening with a clean probe. Close valve.
  • Insert cartridge into dispensing gun. Open valve. Dispense a small amount of adhesive making sure that both components freely flow from the cartridge.
  • Attach the mixing tip to the cartridge. Press the dispensing gun to dispense and discard approximately 1 – 2 inches (2.5 – 5.0 cm) of the product, ensuring that the product is mixed properly in the mixing tip before use. If the mixing tip is left on the cartridge for a sufficient length of time without additional use, the adhesive may cure in the tip. If this happens, keep the mixing tip on the cartridge. When you are ready to dispense more adhesive, replace the mixing tip on the cartridge with a new one. Be sure to discard 1 – 2 inches (2.5 – 5.0 cm) of the product before use.

Shelf Life

One year in unopened cartridge. The date code of manufacture is stamped on the bottom of the cartridge. Shelf life is reduced at higher temperatures and enhanced at lower temperatures. To optimize shelf life, refrigerator storage is recommended and/or store away from direct sunlight between 50° F – 80° F (10° C – 27° C). Keep away from sources of heat, open flame, sparks, sunlight and moisture.

Safety and Environmental Precautions

This product is a flammable, reactive adhesive. It is considered a hazardous material. In conformance with the Federal Hazardous Substance 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. VOC emissions do not exceed 250 grams per liter.

DANGER! 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 between 50° F – 80° F (10° C – 27° C). Use only in adequate ventilation. Avoid breathing of vapors. Atmospheric levels should be maintained below established exposure limit values. See Section II of 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, goggles and impervious apron should be used. Carefully read Material Safety Data Sheet and follow all precautions.

Component A contains Methyl Methacrylate Monomer (80-62-6). Component B contains Catalyst-Initiator and Benzoyl Peroxide (94-36-0). Do not use this product for other than intended uses.
