BC-22
Armature Balancing Putty
DESCRIPTION
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 hours 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° Fahrenheit (oven or heat gun). BC-22 can be drilled,
tapped, or sanded. This product may contain fillers that may settle over time. Product may need to be stirred before using.
Customer must determine suitability of product before using.
