Waterproof painting

Description

Inorganic coatings mainly use inorganic binder silica sol as the film-forming material. The particle size of silica sol is small enough to penetrate into the crevices. Silica sol is a mineral in nature, free from harmful substances, non-toxic, odorless and non-irritating coating material. It is harmless to the environment and human health.

Features

  1. Film formation at room temperature
  2. Completely water-resistant, soaked in water will not turn white
  3. High weather resistance
  4. Crystal penetration waterproof technology
  5. Fire resistance up to 800 degrees
  6. UV resistance and heat insulation
