LIFE/CURE TIME The pot life (working time) of adhesives is measured from the time the hardener ` <br /> & SC-10 and resin are first mixed, until the adhesive starts to thicken and harden and can <br /> no longer be used. The table indicates the pot life of a 6.8 ounce adhesive kit <br /> under various temperature conditions. This table also indicates the cure time <br /> required prior to testing of the bond. In hot weather conditions, mixed adhesive <br /> may be kept cool by wrapping a damp rag around the can in order to extend the <br /> pot life. <br /> Temperature°F 60" 70 80 100 120 150 <br /> °C (16) (21) (27) (38) (49) (66) <br /> Pot Life 45 25 15 8 - - <br /> (minutes) <br /> Cure Time` 12 5 4 3 2 1'/2 <br /> (hours) <br /> `. ' The full indicated cure time must elapse prior to testing. See note below for <br /> accelerated curing. <br /> " At temperatures below 65°F (18°C), an external heat source must be used to <br /> force cure the adhesive. The adhesive should be warmed to 70°F (21°C) prior to <br /> mixing and application of the adhesive. Adhesive may be force cured by using a <br /> hot air gun, an Ameron heating blanket that will completely cover the Containment <br /> • fitting, or a forced air heater if the trench is covered to contain the heat. At <br /> temperatures below 40°F or if it is windy, plug the end of the pipe before curing <br /> and wrap insulation over the heat blanket and fittings, if using heat blankets to <br /> cure the adhesive. <br /> SEALING SECONDARY After primary lines have been successfully tested, the Containment system can be <br /> SYSTEM sealed. For the adhesive to perform properly, the pipe and fitting surfaces must <br /> be free from contaminants, (e.g., water, soap, oil, grease, dirt, etc.) and lightly <br /> sanded. Care must be taken to ensure that each leg of the Containment pipe goes <br /> into the Containment fitting straight and is not disturbed until the adhesive has <br /> cured. Note that stepping on the Containment pipe before the adhesive is cured <br /> can disturb the joints enough to cause leaks. <br /> Before bonding the Containment fittings to the pipe, strap a section of pipe to the <br /> primary pipe where the Containment coupling fittings will later be installed. The <br /> length of this pipe should usually be 11 inches long. This pipe section is to prevent <br /> the Containment pipe from being forced out of the Containment fittings by <br /> hydraulic action during bonding. <br />
