Product composition and characteristics This product will be inorganic - Organic graft modified resin re chelates as Film-forming substance , add flakes nanometer Grade mica, alumina as coating filler 。 coating Temperature resistance can reach six hundred ℃, good adhesion, can be painted on any material to resist the passage of insulation shielding current under high temperature, and prevent corona discharge. The coating is compact, with high resistivity, good dielectric constant, no electronic seepage and tunneling effect, high hardness, and long wear resistance service life.
Working mechanism In paint ceramics The particles are the main components of the film-forming material, which can withstand higher temperatures; Alumina, silicon nitride and other fillers have high volume resistivity and compact structure. Strictly control the proportion of raw materials in the production process to avoid the introduction of stray ions, especially alkali metal or alkaline earth metal ions; The content of glass phase shall be reduced as far as possible, and the conductivity of glass phase added to improve process performance shall be reduced as far as possible. In the production process, attention should also be paid to strictly controlling the introduction of iron, cobalt and other metal ions with variable valence to avoid free ions and holes. At the same time, the temperature and atmosphere in the production process shall be strictly controlled to avoid the occurrence of electrons and holes due to redox reaction and crystal defects due to lattice transformation.
Typical use Motor, electrical appliance, winding coil motor, induction equipment, insulating floor, transformer coil, winding and various insulating fiber materials.

surface treatment
Ensure that the painted surface is free of dust, oil stain, rust, brittle layer and other foreign matters, and ensure that the painted surface is clean and dry without pollution. Polish and roughen the coated surface as much as possible to ensure 25-40 μ m The surface roughness of the range. If the metal surface is manually polished to St3 Grade or sand blasting to Sa2.5 Grade, the coating effect will be better.
Construction method
spray: Use air spraying or airless spraying.
Brush or roller coating: Brush coating or roller coating shall be carried out by cross method.
