Material Notes:
TRA-BOND CA-20 is a thixotropic epoxy adhesive system specially formulated for shorted turns, damaged end wire extensions, or other coil repair applications where a high-fill, non-sag adhesive is required. It is dark-red to brown in color to blend with many commonly used insulating varnishes, and it provides a combination of high dielectric isolation coupled with good mechanical strength. Solvent-free TRA-BOND CA-20 is readily mixed, handled, used and cured at room temperature and develops strong bonds to most materials, including metals, glass, ceramics, and many other coil coatings and insulators. When fully cured, this epoxy adhesive provides excellent resistance to galvanic action, petroleum lubricants and solvents, salts, mild acids and alkalis, other organic and inorganic compounds, and weather.Information provided by Tra-Con Inc.
