ARk <br />F[B>ERCLASS PEm GROUP <br />P'SX-2O Adhesive Kit <br />Epoxy siloxane adhesive for bonding fiberglass <br />pipe and fittings with tapered joints. <br />Description <br />PSX• 20 adhesive is a patented two-part epoxy siloxane adhesive designed for <br />permanently joining fiberglass pipe and fittings with taper/taper joints. PSX•20 is a non- <br />Minimum Joint <br />fiowing thixotropic paste offered in easy-to-use kits. The PSX•20 epoxy adhesive kit <br />Cure Time <br />contains an adhesive resin, hardener, mixing spatula, brush and assembly instructions. <br />--- <br />The adhesive resin is a dark red paste with sand, The adhesive hardener is a white <br />12 <br />paste. The mixed adhesive color is red. PSX•20 can be used to connect epoxy, vinyl <br />6 <br />ester or phenolic systems. <br />Preparation of <br />Using the sandpaper supplied in the adhesive kit, clean both surfaces thoroughly to <br />bonding surface <br />remove all dirt, grease and foreign materials. Make sure the bonding surfaces are free <br />of moisture. <br />Do not touch the bonding surfaces with bare hands, dirty or greasy gloves or rags atter <br />cleaning them. <br />Mixing the adhesive <br />in cold weather it is necessary to warm the resin to 50°F (10°C) to permit good mixing <br />and easier application. <br />Open the hardener container. Using the stick supplied, mix the hardener. Put all of <br />the hardener into the resin container. The mix ratio is 4 to 1. Never split a kit. <br />Pot life and At 77 `F (25°C) the pot life of PSX • 20 adhesive is 20 to 30 minutes. The pot life <br />Cure time decreases with rising temperatures: <br />Adhesive <br />Minimum Joint <br />Temperature Pot Life (min.) <br />Cure Time <br />('F) (_°C)-- <br />----- --- <br />----50 <br />--- <br />^ 10 70 <br />12 <br />65 18 40 <br />6 <br />75 24 25 <br />4 <br />95 35 10 <br />3 <br />In extremely cold or windy conditions, use insulation to prevent rapid dissipation of <br />heat from the cure reaction. Cap the ends of the piping to prevent the passage of cold <br />air. In severe cold conditions, warm air may be blown through the interior of the pipe. <br />A heat cure is recommended for installations with service temperatures above 180°F <br />(82`C) or operating pressures over 300 psi. For ambient temperature conditions below <br />50°F (10°C), an external heat cure must be used. -A minimum heat cure time of at least <br />30 minutes is recommended for 2- through 6 -inch pipe. Even after the adhesive has <br />turned solid at ambient temperatures, heat curing will promote chemical cross -finking <br />of the adhesive, thus increasing its strength, temperature resistance and corrosion <br />resistance. A single Chem Cure Pak may be applied or an Ameren-approved electric <br />heat blanket may be used. The heat cure may be applied at any time after the bond is <br />made and before the pipe has been tested or put into service. <br />Kit sizes and Adhesive kits are available in 3-, 5- and 8 -oz. sizes. The table below indicates the <br />bonds per kit number of bonds per kit for each pipe size. Values in the table are based on the quantity <br />of adhesive required by an experienced crew working at a temperature of 75°F (24'C) <br />with a 30 minute adhesive pot life. <br />Kit size Bonder kiteui e�size` <br />(oL) 2 - 3 4 -- - 6 8 10 12 14 16 <br />3 7 5 4 2 1 1 — — — <br />5 12 8 6 3 2 2 1 1 — <br />8 -- 14 9 4 3 3 2 2 1 <br />FPF,QRA r?/n1i <br />
