What is Lithium polysilicate CAS 12627-14-4?
Lithium polysilicate CAS 12627-14-4 is an inorganic chemical compound consisting of lithium ions and silicate anions, most commonly supplied as a clear, aqueous solution. Because lithium is the smallest alkali metal, Lithium polysilicate CAS 12627-14-4 features an extremely small molecular size, allowing it to penetrate porous substrates like concrete much deeper than sodium or potassium silicates. It is highly valued in the construction, marine, and manufacturing industries as a premium concrete densifier, surface hardener, and inorganic binder. Upon application, Lithium polysilicate CAS 12627-14-4 reacts with free lime to form a durable, insoluble matrix that resists moisture, chemical attacks, and environmental weathering.

Features
- Deep Substrate Penetration: Thanks to the small atomic size of lithium, it penetrates deep into porous surfaces to form a dense, insoluble calcium silicate hydrate (C-S-H) gel from the inside out.
- Efflorescence Resistance: Unlike traditional sodium or potassium silicates, it does not leave behind white, chalky salt deposits (efflorescence) upon curing, ensuring a clean and clear surface finish.
- ASR Mitigation: Actively suppresses the Alkali-Silica Reaction (ASR), preventing the internal expansion, cracking, and degradation of concrete structures over time.
- Ease of Application: Formulations go on easily, do not require heavy water-flushing to remove excess material, and dry to a smooth, high-gloss finish when polished.
Applications
- Concrete Densifiers & Hardeners: Extensively applied to concrete floors in warehouses, garages, and retail spaces to increase surface hardness, eliminate concrete dusting, and improve abrasion resistance.
- Anti-Corrosive Marine Coatings: Serves as a highly reliable inorganic binder in zinc-rich paints and protective coatings to protect steel structures in harsh industrial and marine environments.
- Adhesives & Sealants: Formulated into specialized sealants and adhesives to enhance bonding strength and structural stability, particularly for high-temperature applications.
- Ceramics & Glass Production: Acts as a specialized flux and inorganic binder in the manufacturing processes of advanced ceramics, enhancing thermal stability and material integrity.
