TECHNICAL DATA BULLETIN <br /> VersiWelde Bonding Adhesive <br /> Application <br /> ■ <br /> 1 The surface,on or against which adhesive is to be applied, shall <br /> be clean,smuolh,dry,free of tins,sharp edges, loose and foreign <br /> materials,oil and grease Depressions greater then 1/4"(6 mm) <br /> should be feathered, using epoxy, mortar or other approved <br /> patching material All sharp projections shall be removed by <br /> sweeping,blowing or vacuum cleaning. <br /> 2 After thorough stirring(minimum 5 minutes),apply VersiWeld <br /> Bonding Adhesive to substrate and membrane using a 9°(23 mm) <br /> medium nap roller Application shall be continuous and uniform <br /> avoiding globs or puddles An open time of 5 to 50 minutes, based <br /> on drying conditions is recommended before assembly.VersiWeld <br /> Bonding Adhesive must be allowed to dry until it does not string <br /> or stick to a dry finger touch Any coated area which has been <br /> exposed to rain shoulo be allowed to dry and then recoated Do not <br /> Overview apply adhesive to splice areas to be hot-air welded <br /> VersiWeld Bonding Adhesive is a high-strength solvent-based contact 3. Roll the membrane onto the adhesive cooled substrate while <br /> adhesive that allows bonding of VersiWeld TPO membrane to various avoiding wrinkles Immediately brush down the bonded portion of <br /> porous and non-porous substrates the sheet with a soft bristle push broom or a 150 lb segmented <br /> roller to achieve maximum contact <br /> Features and Benefits <br /> REVIEW CURRENT VERSICO SPECIFICATIONS AND DETAILS FOR SPECIFIC <br /> Solvent-based bonding adhesive that allows for quick drying APPLICATION REQUIREMENTS <br /> Can be roller-applied with medium nap roller Precautions <br /> Provides excellent adhesion to various substrates <br /> Review the applicable Safety Data Sheet for complete safety <br /> Coverage Rate information prior to use. <br /> 60 so It.(5.6 mz)per gallon finished surface.Coverage rates are 2 VersiWeld Bonding Adhesive is EXTREMELY FLAMMABLE It contains <br /> overage and may vary due to conditions on the jobsite Porous surfaces solvents that are dangerous fro and explosion hczurds when <br /> and substrates may require more bonding adhesive than the typical exposed to heat,flume or sporks.Do not smoke while applying.Du <br /> coverage rate not use in a confined or unvontilated orec.Vapors are heavier thcn <br /> air and may travel along ground or may be moved by ventilation <br /> Mixing and ignited by pilot ights. other fiames.sparks,heaters,smoking, <br /> electrical motors,static discharge,or other ignition sources at <br /> Stir thoroughly until all settled pigments are dispersed and the adhesive is in <br /> atlnns distant from material handling point and f,ashback.All <br /> uniform in color Minimum 5 minutes stirring is recommended <br /> containers should be grounded when material is transferrea from <br /> one container to another A red caution label is required when <br /> shipping A fire extinguisher should be ovciloble In case of fire, use <br /> water spray, foam,dry chemical or carbon dioxide Do not use a <br /> solid s`ream of water because it con scotter cnd spread the tire. <br /> 3 Avoid breathing vapors Keep container closed when not in use <br /> Use with adequate vertilotion If inholed,remove to fresh air If not <br /> b,00thing,perform ortiliciol respirolion.If breathing is cMicr1l,give <br /> oxygen Call a physician immediately During application,efforts <br /> must be made ro prevent fumes from entering the builcing via air <br /> ventilation ducts Do not place open containers or mix adresive <br /> VERSIC0 near fresh air intake units When pass ble,shut down or seal oft the <br /> ROOFING SYSTEMS closevurits <br />
