†Substrate thickness: 0.25 inch (0.64 cm). Bond area: 1.0 in2 (6.45 cm2)
ADHESIVE PROPERTIES AND CHARACTERISTICS @ 73°F (23°C)
*When viewed in large containers, it is not uncommon for the product to show a yellow tint - older product may have a greater propensity for this. However, this appearance is due to the concentration of material. Once applied to the substrate, the product will be clear. The very same clear transparency will be retained during and after curing.
DIRECTIONS FOR USE
SURFACE PREPARATION: Surfaces to be joined should be clean and fit without forcing. It should not be necessary to flex either piece more than a few thousandths of an inch to achieve complete contact. Surfaces should be sanded with 240 to 400 grit sandpaper before bonding. Do not flame polish surface to be bonded.
MIXING: Before mixing, bring both Components (A & B) to room temperature. To adjust viscosity, add no more than 10 cc or grams of SCIGRIP 3061 per 100 cc or grams of Component “A.” Then, add 5 cc or 5 grams of Component “B.” Stir until completely mixed. If base adhesive is above 85°F (29°C), pre-cool to 75°F (24°C) before mixing.
POT LIFE: When mixed, pot life at 75°F (24°C) is approximately 20 minutes. Note: shorter pot life may result where larger masses are used or when temperature is above 75°F (24°C).
PRELIMINARY ANNEALING: To prevent crazing during bonding, acrylics should be annealed following machining and forming. (Refer to acrylic sheet manufacturer’s published Annealing Schedules.)
MAKING THE JOINT: Apply adhesive with suitable applicator to one or both surfaces and assemble immediately. If cellophane masking tapes are used, avoid contact of SCIGRIP 40 with the glue side of tape. Apply just enough pressure to remove air bubbles. Do not squeeze parts too hard as to force adhesive out of joint, a dry joint could result. If possible, cover joint with cellophane to prevent inhibition of cure by air.
CURE TIME: At 70°F (21°C), a film thickness of 0.020 inch (0.508 mm or 20 ml) will typically be tack free in 7 to 8 minutes. The bond will harden in 45 to 60 minutes, and for most applications it can be handled in approximately 4 hours. Machining of the assembly can usually be done after 24 hours.

WARNING! 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 in a cool 50º – 80ºF (10º – 27ºC) dry place. Use only in adequate ventilation. Avoid breathing of vapors. Atmospheric levels should be maintained below established exposure limit values. See Sections II and VIII 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. Contains Methyl Methacrylate Monomer (80-62-6). 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 Material Safety Data Sheets that are copied and distributed for this material.
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.
