SECTION 7 ♦ Adhesive Bonding Sr Curing TABLE 2.7.1 Number of Containment Fitting Bonds per Adhesive Kit • Dirt contamination can be removed by water washing. Be sure the surfaces are dry before bonding. Note: Use of a solvent as a cleaning method is optional. If preferred by the customer, use solvent. 1,1,1 trichloroethane is available from Smith Fiberglass Products. Some alternate cleaning solvents available through local hardware or industrial supply houses are acetone, alcohol, methylene chloride, and methyl ethyl ketone. After cleaning, be sure any residual solvent has evaporated before applying adhesive. DO NOT USE SOL- VENTS THAT LEAVE AN OILY FILM ON THE BONDING SURFACES. WARNING: Some degreasers and solvents are ex - Atremely flammable. Be sure to read warning labels on containers. Never use alcohols, gasoline, turpen- tine, or diesel fuel to clean joints. If you have any questions, please contact your Smith Fiberglass Products' representative. Bonding surfaces must be dry, so be sure all solvent has evaporated from the surfaces before applying adhesive. 2.7.3 Bonding After cleaning all sanded surfaces, apply a thick coating (X611/1.6 mm minimum) of adhesive to the socket area of the containment fitting. Liberally coat the flanges (flat bonding surfaces) of both halves of the fittings with adhe- sive (V'/1.6 mm minimum thickness). See Fig. 2.2.5. Next, apply a thick coating (X6"f 1.6 mm minimum) of ad- hesive to the scarfed or sanded surfaces of the pipe ends. Assemble the containment fitting by placing the half with the pre-installed threaded female inserts on the bottom. 2.7.4 Assembling and Bolting Use the bolts supplied with the fitting to assemble the fittings on the pipe (see Fig. 2.2.5). Use of an air or elec- tric wrench with a magnetic socket will greatly facilitate assembly. When starting the bolts, allow the bolt to start with minimal pressure on the tool. Excessive pres- sure may push the insert from the fitting. Tighten the bolts alternately and with equal force. DO NOT EXCEED 8 FT.•LBS. OF TORQUE! Make sure that the pipe fits snugly into the socket ends of the fittings and that there are no gaps between pipe ends and fitting sockets. 2.7.5 Precautions Take care not to disturb a completed containment piping joint when assembling additional joints. The adhesive must be fully cured before applying stress to the assem- bled joints. Read and observe the following precautions: Avoid contact with the adhesive and hardener, since they are capable of causing skin and eye irritation. Gloves and eye protection must be used. If contact is made, flush eyes with water and wash skin with soap and water. Do not in- hale hardener fumes; work in well -ventilated areas. 2.7.6 Adhesive Cure IMPORTANT: For secondary containment systems con- veying petroleum products, alcohols, and alcohol/gasoline mixtures, you must use DS -8000 or DS -7000 series adhe- sive for bonding. Electric heating collars or Smith Heat Packs from Smith Fiberglass Products can be used to short- en cure time. We recommend external heat to assure full adhesive cure when ambient temperature is below 70°F (21-C). After curing, pipe should not be handled or used until the joint returns to ambient temperature. 1. Electric heating collars Approximate adhesive cure time when using electric heating collars on secondary containment fittings is 25 to 35 minutes per joint. See Part One, Section 6 and Table 1.6.3 for additional heating collar information. • • Two heating collars are required for each end of a con- tainment fitting bond (see Fig. 2.7.1). 0 28 Installation Instructions DS -7014 or DS -8014 DS -7069 or DS -8069 (Approx.
