AB Adhesive
A white, high-purity (99.98%) alumina polishing powder that mixes very easily with water without clumping, suitable for polishing special materials to meet high-quality surface requirements in precision optics. 1. Bonding surfaces should be dry and clean, free of dust, oil, and other contamination. Sandpaper may be used to roughen the bonding surfaces for optimum adhesion. 2. Mix the adhesive components at a ratio of 82/8267=1:1. The mixed adhesive is ready for use when its color changes from orange-red to green. 3. Hardening should take place in a curing oven; please refer to the following for the specific hardening temperature and time: At room temperature, the unmixed material has a shelf life of approximately 2 years. One 8266A 70 g tube and one 8267B 60 g tube per box. 8266A/8267B are also supplied in one-kilogram pails each.
