· JVASP-139600· NaSiO2

Sodium silicate (Na₂SiO₃), commonly known as water glass, is an inorganic ceramic compound formed from silica and sodium oxide. It is typically produced as a glassy solid or viscous aqueous solution and belongs to the silicate ceramic family. This material is valued in industrial applications for its adhesive properties, thermal stability, and chemical durability, particularly in settings requiring inorganic binders or coatings rather than organic alternatives.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
