Weld-On #40 - Low VOC Acrylic Plastic Adhesive 2-Part Kit (Pint)

Description: SCIGRIP IPS Weld-On #40 - Low VOC Acrylic Plastic Adhesive 2-Part Kit (Pint)Weld-On 40 is a two-component, clear, medium syrupy, low VOC, reactive acrylic adhesive. It polymerizes at room temperature, forming high strength joints within a few hours. The cemented joint retains high clarity, good strength and resistance to the effects of weathering and aging. In cases where a lower viscosity is desired, Weld-On 3061 may be used as a reactive diluent. When adjusting viscosity, similar curing characteristics will be maintained when no more than 10% of Weld-On 3061 is added to Weld-On 40 Component “A.” This product meets Military Spec A-8576C Type III.Substrate RecommendationsWeld-On 40 is especially formulated to bond extruded, cast, and cross linked acrylic (poly-methyl methacrylate) sheets. It will also bond acrylic to polyester, cellulose acetate butyrate, polycarbonate, PVC, ABS, PETG and other materials.Bonding RecommendationsWeld-On 40 is recommended for bonding of acrylic plastics especially where good clarity retention is required. It is versatile and can be used in many applications such as sign fabrication, the manufacturing and repair of aquariums, museum quality display cases and other plastic fabrication.Directions for UseSURFACE 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 Weld-On 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 Weld-On 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.Shelf LifeOne year in tightly sealed containers stored away from direct sunlight in a cool 50º F – 80º F (10º C – 27º C) dry place. Storage near the ceiling in non air-conditioned warehouses is not recommended. Shelf life is reduced at higher temperatures and enhanced at lower temperatures. Keep away from sources of heat, open flame, sparks and sunlight. The date code of manufacture is stamped on the bottom of the container.
