BC-22 is a epoxy balancing compound for use in weight addition balancing of electric motor armatures, rotors and fans. BC-22 has a smooth, fibrous, putty-like consistency which keeps the compound from migrating during the balancing process. The components of the BC-22 are mixed 1:1 by volume or by weight. The BC-22 may then be placed on the motor armature as indicated by the balancer. Move add or subtract BC-22 as necessary to obtain final balance. The working life of the mixed BC-22 is about 2 hr depending upon mass and temperature. - Overnight BC-22 cures to a solid polymer, which resists moisture and solvents. BC-22 may also be heat cured at 250 °F(oven or heat gun). BC-22 can be drilled, tapped or sanded. This product may contain fillers that may settle over time.
