Lawatherm is a specially designed durable, high dielectric insulating material, which replaces old style epoxies, polyster and varnishes insulation systems. Application of these materials is crucial. This is why special heating equipment to properly cure the insulation is required with these materials. Utmost care should be given to apply the material to provide uniformity of application.
Maximum precaution is taken to insure that the first layer of insulation is applied to the accurate amount of thickness and properly cured before the second coat is applied. If the first coating is too thick or not properly cured, "outgassing" can occur, causing turn to turn arcing and premature failure of the coil. Special high-voltage electrical tests are carried out on the entire coil to insure the integrity of the insulation. Lebond 2216 has been heated to450°F and subjected to high voltage non-destructive tests [up to 6000 Volts DC] with no indication of failure. Flexocoat lebond 2216 for coating induction coils of electric induction furnace, it has excellent adhesion on copper and stainless steel desired flexibility to withstand cooling and heating cycles normally encountered during operation of furnaces and provides electrical resistance to voltage developed between the coils to protect from sparking, upto approximately 400 volts/ mill. Thickness of coating.
