Bonding primary Joint preparation <br /> systems All tapered systems must be clean,dry and warm for a proper bond. <br /> Clean:Pipe is shipped from the factory with end protectors.Avoid contamination from <br /> fingerprints,petroleum fumes,mist and condensation as these are adverse to good <br /> bonding.If a taper becomes dirty,sand it with emery cloth.Never touch the bonding <br /> surface with bare hands after cleaning or sanding as this will leave an oily deposit. <br /> r———————————-- Dry:Adhesive will not bond to a wet surface.If the taper is wet or moist,dry it with a blow <br /> 1 The hardener contained in the 1 dryer or heat gun.Do not overheat or burn the pipe. <br /> 1 adhesive kit may bum the skin. 1 Warm:Below 50°F(10°C),warm the taperwith a blow dryer or heat gun.For best <br /> 1 Avoid inhaling the vapors.Read and 1 results,adhesive should be at least 50°F when used.Do not store kits in areas above <br /> 1 observe the label precautions. 1 100°F(38°C),below 32°F(0°C),or in the direct sunlight during warm weather.In cold <br /> L------------J <br /> weather warm the resin to at least 50°F but not above 100°F to permit good mixing and <br /> easier application. <br /> Mixing Ameron PSX•20 adhesive <br /> • Combine all of both components in the mixing container in the supplied <br /> proportions. <br /> Never try to split a kit. <br /> • Mix thoroughly with the mixing stick until all streaks are gone and the adhesive has <br /> a smooth,uniform color.Mixed adhesive color is red. <br /> • Do not allow moisture to get into the can. <br /> Begin by coating the cut ends of the pipe with <br /> adhesive.Then apply thin,even coat of <br /> mixed adhesive to the inside of the bell and to 1 <br /> the tapered spigot ends(indicated by '11 <br /> shading)or to the entire tapered section in <br /> fittings or adapters,completely wetting all <br /> machined surfaces with the adhesive.Wipe <br /> off excess adhesive with the spatula orbrush <br /> provided in the kit. -JV <br /> Applying Ameron PSX•20 adhesive <br /> Excessive amounts of adhesive may cause flow restriction inside the pipe when the <br /> adhesive has cured,or may result in'hydraulic backout'as the adhesive cures. <br /> Hydraulic backout occurs when excess adhesive prevents thejoint from maintaining an <br /> interference fit and the spigot backs out of the bell during cure. <br /> Making the joint <br /> After aligning the mating surfaces so that they may be brought together <br /> in a straight line: <br /> • Insert spigot all the way into the bell. <br /> • Twist one quarter of a tum when pushing togetherto distribute adhesive evenly and <br /> to achieve an interference fit.A slight reverse turn will then lock thejoint. <br /> • Do not cock thejoint. <br /> • Over-insertion of the joint may collapse the spigot and cause a leakyjoint. <br /> • Under-insertion of thejoint may also cause a leakyjoint. <br /> • Do not drive the joint together with a hammer.If locking cannot be done as <br /> described above,place a"soft"object,such as a 2x4 on the fitting and liahtiv rap it. <br /> • Do not disturb thejoint while the adhesive is uncured. <br /> • Do not move adjacent pipe and fittings until adhesive has set. <br /> Do not directly strike thejoint with I Pot life/cure times for Ameron PSX•20 adhesive <br /> 1 any type of hammer or mallet to ' Pot life is measured from the time the hardener and resin are first mixed until the <br /> make it up. 1 adhesive starts to thicken and harden and no longer can be used.Do not use adhesive <br /> L------------J once the can has become hot. <br /> 9 <br />
