TECHNICAL INFORMATION SHEET I.S.O. Twin Pack™ Insulation Adhesive Solvent Free and VOC Free Contains no HCFC or CFC Can be suitable for cold weather applications when stored properly. Firestone Item Number: W56RACINTA DESCRIPTION: I.S.O. Twin Pack Insulation Adhesive is a two-component low-rise polyurethane adhesive designed for anchoring acceptable roof insulation to acceptable substrates, and to adhere multiple layers of insulation. I.S.O. Twin Pack Insulation Adhesive is dispensed using I.S.O. Twin Pack Hand Dispenser (Firestone Item No.: W56RACINTG); I.S.O. Twin Pack Four Bead Dispenser (Firestone Item No.: W56RACINT4); Multi-Bead Plus Dispenser; Battery Powered Single Bead Applicator or a Pneumatic Single Bead Applicator. The dispensers extrude I.S.O. Twin Pack Part A and B simultaneously to the static mixer, which results in a mixed adhesive in bead form. Firestone Building Products standard warranties are available up to 30-year warranty period. Please refer to the Firestone Technical Database at www.firestonebpco.com for specific warranty requirements. COVERAGE RATE: Each I.S.O. Twin Pack kit, when properly mixed, dispenses 150 ft (45.7 m) of mixed adhesive in a bead 1/2” (12.7 mm) wide. This bead will rise to 3/4” - 1” (19.0 mm - 25.4 mm). This equates to 600 ft² (55.74 m²) per carton when installed in beads 12” (304.8 mm) on center (typical spacing). Note: Coverage rate may be reduced due to irregularities in substrates. Coverage rates for other bead spacing: 6” (152.4 mm) on center: 300 ft² (27.87 m²)/CTN 4” (101.6 mm) on center: 200 ft² (18.58 m²)/CTN TYPICAL SET-UP TIMES: At 60 °F (15.6 °C) to 90 °F (32.2 °C): approx. 5-8 minutes At 35 °F (2 °C) to 60 °F (15.6 °C): approx. 8-15 minutes PHYSICAL PROPERTIES: Property Minimum Performance Color, Part A: Amber Color, Part B: Off-white Composition, Part A: Isocyanate pre-polymer Composition, Part B: Polyol Mix Ratio of A:B: 1:1 by volume Specific Gravity, Part A: 1.18 + 0.06 Specific Gravity, Part B: 1.02 + 0.05 Viscosity, Part A or B: 3,000-24,000 CPS, #5 spindle @ 5 RPM, 77 °F V.O.C. Content: 0 g/L I.S.O. Twin Pack Insulation Adhesive can be installed at temperatures as low as 200 F (-6 0 C) up to 1000 F (380 C) when material is stored between 600 F and 800 F. The substrate must be clean, smooth, dry, free of sharp edges, loose and foreign materials, oil, grease, and other contaminants. To mix and dispense I.S.O. Twin Pack Insulation Adhesive from kits, remove plugs and apply the static mixer over plug end of kit by hand tightening static mixer to kit with plug end facing up. Keep plug end facing up until you are ready to dispense I.S.O. Twin Pack Insulation Adhesive to the deck substrate. Properly mixed I.S.O. Twin Pack will be yellow, with no marbling. Part A and B will be extruded simultaneously through dispensing equipment. To stop dispensing I.S.O. Twin Pack Insulation Adhesive, stop the dispenser plunger from advancing and point the mixing end up to stop Part A and Part B from entering static mixer. This stopped position of the kit can only be maintained for several minutes, as Part A and Part B already in the static mixer will continue to react, set up, and block the static mixer. If the static mixer becomes blocked during stopped period, replace static mixer in order to mix and dispense the remaining Part A and Part B in kit. Apply I.S.O. Twin Pack Insulation Adhesive in a bead 1/2” (12.7 mm) wide to deck substrate in spacing as specified for the project. The adhesive will rise to a bead of 3/4” – 1” (19.0 mm – 25.4 mm) within minutes after placement. Rise time will depend on the ambient conditions: warmer=faster; cooler=slower. SHELF LIFE: When I.S.O. Twin Pack is stored in original unopened container indoors away from direct sunlight between 60 °F - 80 °F (16 °C - 27 °C), shelf life is twelve months. For optimum results, rotate your stock to ensure stored material has not exceeded the shelf life of one year. To ensure that the insulation makes continuous contact with the adhesive during the critical set-up period, set the insulation board [4’ x 4’ (1.22 m x 1.22 m) maximum], in fresh I.S.O. Twin Pack insulation adhesive before a skim coat develops. Immediately after setting each insulation board, weight each board using full pails of Bonding Adhesive or other available source of weight that will not damage the roof insulation. STORAGE: Store in original containers at temperatures between 60 °F - 80 °F (16 °C - 27 °C). Store cartons with kits on their side. DO NOT store kits with plunger or plugged end down to avoid the possibility of leakage. PACKAGING: I.S.O. Twin Pack Insulation Adhesive is packaged as a kit consisting of one 750 ml Part A cartridge fastened together with one 750 ml Part B cartridge. Each case contains: 4 Part A – Part B Kits 6 Static Mixers Instruction Sheet Weight of each case is about 20 lb (9 kg) 48 cases per pallet
