E-'u;awcc.Ass-Composrrr: PwE Gxour PSXTM*20 Adhesive Kit - Epoxy siloxane adhesive for bonding fiber- glass pipe and fittings with tapered joints. Description PSX•20 adhesive is a patented two-part epoxy siloxane adhesive designed for permanently joining fiberglass pipe and fittings with taper/taper joints. PSX•20 is a non -flowing thixotropic paste offered in easy-to-use kits. The PSX*20 epoxy adhesive kit contains an adhesive resin, hardener, mixing spatula, brush and assembly instruc- tions. The adhesive resin is a dark red paste with sand, The adhesive hardener is a white paste. The mixed adhesive color is red. PSX•20 can be used to connect epoxy, vinyl ester or phenolic systems. Listings and approvals Ameron PSX•20 adhesive is Listed by Underwriters Laboratories (UL) under File MH 9162 for use in Nonmetallic Underground Piping for Flammable Liquids. PSX•20 UndP.rwiters UL Laboratoriesinc.® adhesive is particularly suited for piping systems conveying petroleum products including diesel fuels, kerosene, etc., alcohols and alcohol -gasoline mixtures, or oxygenated fuels. It is also approved by Underwriters Laboratories for use with MTBE fluids. Preparation of Using the sandpaper supplied in the adhesive kit, clean both surfaces thoroughly to bonding surface remove all dirt, grease and foreign materials. Make sure the bonding surfaces are free of moisture. Do not touch the bonding surfaces with bare hands, dirty or greasy gloves or rags ' after cleaning them. ' Mixing the adhesive In cold weather it is necessary to warm the resin to 50°F (10°C) to permit good mixing and easier application. Open both resin and hardener containers. Using the stick supplied, put all of the hardener into the resin container. Never split a kit. Pot life and At 77°F (25'C) the pot life of PSX•20 adhesive is 20 to 30 minutes. The pot life Cure time decreases with rising temperatures: Adhesive Minimum Joint Temperature Pot Life (min.)

Cap the ends of the piping to prevent the passage of cold air. In severe cold conditions, warm air may be blown through the interior of the pipe. A heat cure is recommended for installations with service temperatures above 180°F (82°C) or operating pressures over 300 psi. For ambient temperature conditions below 50°F (10°C), an external heat cure must be used. A minimum heat cure time of at least 30 minutes is recommended for 2- through 6 -inch pipe. Even after the adhesive has turned solid at ambient temperatures, heat curing will promote chemical cross-linking of the adhesive, thus increasing its strength, temperature resistance and corrosion resistance. A single Chem Cure Pak may be applied or an Ameron-approved electric heat blanket may be used. The heat cure may be applied at any time after the bond is made and before the pipe has been tested or put into service. U.S. Patent No. 4250074, 4257645 �— — FP698A (5/01)
