Star Technology BC-22 Part A and B Balancing Compound, 2 lb Kit, Blue/Yellow
ID: STAR22BCA/B2LBKIT | Mfr ID: BC22-2LBManufactured by: Star Technology

BC-22 is a two-part 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 two-components of the BC-22, parts A and B, are mixed 1:1 by volume or by weight. BC-22 part A blue and BC-22 part B yellow are easily mixed by hand until the color is a consistent green.

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.
