Precipitated Silicon Dioxide as Matting Agent Used For Wood Coatings and Industrial Coatings
Introductions
Precipitated Silicon Dioxide is a manufactured by treating Sodium silicate with mineral acid. The mineral acid can be either Hydrochloric acid or Sulphuric acid. The content of the settler will be the slurry containing Precipitated silica and Sodium sulphate/Sodium chloride solution, which would be filtered in a filter press. The filtered cake is washed and dried on tray dryer or spray drier.
Feature
Typical applications for amorphous precipitated silica include: free-flow and carrier agents for agricultural and industrial chemicals; flatting, thickening and anti-corrosion additives for paints and coatings; microporous fillers for battery separators; performance-enhancing fillers for tire, industrial and silicone rubber applications; and non-black reinforcing agents for rubber shoe soles and footwear.
Application Fields
1, General NC wood coating, PU wood coating, furniture wood coating, wood decorative coating.
2, General Industrial Coating, Metal baking Coating, Decorative Coating.
Superiority
We are aim to become the highest quality Synthetic Silica Producer in China and the foreign Country. And Adhere to excellence in products and services. We will aim to achieve the international acceptable quality products and reliable supplier.
