ADHESIVES Two basic adhesive systems are available from NOV Fibtr Glass Systems. The 7000 and 8000 series adhesives differ in operating characteristics and working time (pot life). See Table 6 for recommended usage and approximate number of bonds per kit. The working life of each kit is based on an ambient temperature of 75' F (24° C). The adhesives are a two -component system that must be mixed prior to use. Detailed instructions for adhesives are provided with each kit. Read instructions thoroughly and follow the recommended procedures. Refer to Adhesive Working Life for both warm and coot weather conditions. ADHESIVE MIXING Thoroughly mix the adhesive. Complete information and safety precautions are packaged with each adhesive kit. Review all safety precautions thoroughly before mixing the adhesive. • At 65'F or below, pre -warm the adhesive kits to 70' to 80'F minimum. • Empty all of the contents of the hardener bottle into the can of base adhesive. • Mix all of the adhesive with all of the hardener. NEVER SPLIT A KIT. • Do not spill hardener during the mixing process. Cut through the adhesive with the edge of the mixing stick to assist in mixing the two components. r ""r"1" • Mix until the adhesive has a uniform color and a consistent flow off the mixing stick. Wipe down the sides, Adhesive bottom, and under the rim of the can with the mixing stick to assure complete mixture. ADHESIVE WORKING LIFE Working life or pot life is the time it takes for the adhesive to harden in the mixing can. This time is measured from the time the adhesive and hardener are first mixed. Working life is shorter at temperatures above 751F (21 °C) and becomes longer as the temperature drops below 75°F (21 °C). Working life is affected by the quantity of mixed adhesive as well as by temperature. Use the following methods to optimize the working life of adhesives: Warm Weather: • Occasionally stir the adhesive mixture during application. • Use small ice chests or other containers with freezer packs to keep adhesive cool. Cool Weather: • Store adhesive kits inside. • Pre -warm to between 70'-80`F (21.1'-26.7'C) before use. CAUTION: If adhesive becomes warm and starts to harden in the container, discard immediately. DO NOT USE THIS ADHESIVE TO BOND A JOINT! When adhesive is allowed to harden in the metal container, the container may reach approximately 400'F (20510). Do not handle hot containers without heavy gloves. The exothe-n-nic reaction will generate a dense, foul-smelling smoke. Place the container outdoors in an open area until it cools. Avoid inhaling smoke. ADHESIVE DISPOSAL: Once the adhesive and catalyst have been mixed and reacted, nothing can be extracted, and it is classified as non -hazardous material. Dispose of in a normal manner as other solid waste. Excess adhesive and catalyst can be mixed, allowed to react, and disposed of as above. If extra cans of adhesive or tubes of catalyst have accumulated without the other component to mix and react, contact your regional manager. Catalyst tubes, when empty are not subject to EPA regulation and can be disposed of in a normal manner. These guidelines are based on federal regulations. State and local regulations and ordinances should be reviewed. LO
