Star Technology BC-22 Part A and B Balancing Compound, 2 lb Kit, Blue/Yellow

ID: STAR22BCA/B2LBKIT Mfr ID: BC22-2LB
Manufactured 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.
