YM NANO SILICA

Coatings & Construction Industry

This field focuses on binding strength and film hardness. Sodium-stabilized types are common due to cost-effectiveness.

· Inorganic Mineral Coatings

   · Common Type: Alkaline (pH 9-11), Sodium or Potassium-stabilized.

   · Solid Content: 25% - 30%.

   · Particle Size: 8-20 nm.

   · Function & Principle: As water evaporates, SiO₂ particles react with Ca(OH)₂ in the substrate to form a strong chemical bond (calcium silicate), hardening the inorganic coating.

· Water-based Wood/Industrial Paints

   · Common Type: Acidic or Neutral (for compatibility with acid resins), Unstabilized.

   · Solid Content: 20% - 30%.

   · Particle Size: 10-30 nm.

   · Function & Principle: Fills resin pores, utilizing the high hardness of SiO₂ to enhance scratch resistance and film density.
