· K2SiO3

K2SiO3 (potassium silicate) is an inorganic ceramic compound belonging to the silicate family, commonly available as a colorless liquid or solid form known as water glass or potassium water glass. It is widely used in manufacturing adhesives, binders, and coatings in construction, automotive, and industrial applications, valued for its strong bonding strength, high-temperature stability, and cost-effectiveness compared to organic alternatives. The material is notable for its role as a silica source and binder in refractory products, investment casting molds, and corrosion-resistant coatings, making it particularly relevant in extreme-temperature and heavy-industry environments.

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.
