High temperature anti-corrosion coating

Description

The surface of metal is corroded by an acid or an alkali easily, the traditional method to prevent corrosion was to coat an organic layer on the surface of metal, but the capability of weather-reliability was not good enough to protect the substrate from high temperature. There were  properties of high hardness, flame resist and high temperature resist on the EST coating material from GiantNano, it can hit high hardness request even in the high temperature environment. Additionally, the color of EST can be changed to achieve customer's request. 

Feature

  1. Burning resistance and heat-resistant 
  2. High hardness
  3. Low curing temperature
  4. Weatherability 
  5. Colorful
