Electric Insulating Lacquers

Electric Insulating Lacquers

Used for impregnation of cables, transformers, electrical motors and apparatus.

Varnish KO-916K

Features

Homogenous clear solution of polyether-modified organopolysiloxane resin in organic solvents.
    • Lacquer KO-916K serves for impregnation of winding of electric apparatus, transformers with class H insulation, electrical machines and apparates with tropicalized and maritime construction.
    • The lacquer is successfully used for repairs of load-lifting magnets, coils of electromagnetic separators as well as redesign and repairs of electrical machines.
  • The polymerized lacquer coat is nontoxic, fire-safe.
  • Shelf life - 6 Months
