• Do not spill hardener during the mixing process. Cut <br />through the adhesive with the edge of the mixing stick to <br />assist in mixing the two components. <br />Mix until the adhesive has a uniform color and a consis- <br />tent flow off the mixing stick. Wipe down the sides, bot- <br />tom, and under the rim of the can with the stick to assure <br />a complete mixture. <br />Adhesive Working Life <br />Working life or pot life is the time it takes for the adhesive to <br />harden in the mixing can. This time is measured from the time <br />the adhesive resin and hardener are first mixed. Working life <br />is shorter at temperatures above 75°F (21°C) and becomes <br />longer as the temperature drops below 75°F (21°C). Working <br />life is affected by the quantity of mixed adhesive as well as by <br />temperature. Use the following methods to optimize the work- <br />ing lite of adhesives: <br />Warm Weather: <br />• Occasionally stir the adhesive mixture during applica- <br />tion. <br />• Use small ice chests or other containers with freezer <br />packs to keep mixed adhesive cool. <br />• Spread mixed adhesive on a clean sheet of aluminum <br />foil or cardboard. <br />Cool Weather: <br />• Store adhesive kits inside. <br />• Pre -warm to between 80°-90'F (26.7x -32.2°C) before <br />use. <br />Caution: If adhesive becomes warm and starts to harden in <br />the container, discard immediately. <br />DO NOT USE THIS ADHESIVE TO BOND A JOINT! <br />When adhesive is allowed to harden in the metal container, <br />the container may reach approximately 400°F (205°C). Do <br />not handle hot containers without wearing heavy gloves. The <br />exothermic reaction may generate fumes. Place the container <br />outdoors in an open area until it cools. Avoid inhaling fumes. <br />19 <br />JAI J 17 2J i7 <br />ENVIRONMENTAL HEALTH <br />DEPARTMENT <br />
