Amok f Pot l ife/cure time Piping systems incorporating 320 bonds can be put into service after curing at ambient temperatures for the times indicated in the table.The table also indicates the pot life (working time)of a mixed 5-oz kit at various temperatures.The pot life of adhesives is measured from the time the hardener and resin are first mixed until the adhesive starts to thicken and can no longer be used. Minimum Ambient Adhesive Minimum Joint Temperature Pot Life Cure Time (°F) (°C) (minutes) (hours) 40 5 70 12 65 18 40 5 75 24 30 4 95 35 20 3 In sub-zero or extremely windy conditions,extend the heat-cure times accordingly and use insulation as necessary to insure adequate bonding.Cap the ends of the piping to prevent the passage of cold air.In severe 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 40°F(5°C),an external heat cure must be used.A minimum heat cure time of at least 30 minutes is recommended fort 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.The heat may be applied at any time after making the bond while the adhesive is still liquid or after it has gelled to a solid. Kit sizes and Adhesive kits are available in 1,5,and 8-oz sizes.The table indicates the number of bonds per kit bonds per kit for each respective pipe size.Values in the table are based on the quantity of adhesive required by an experienced crew working at a temperature of 75'F(24°C)with a 30-minute adhesive pot life.
