Potassium methyl siliconate CAS#31795-24-1
Acts as an efficient surface treatment agent, significantly improving surface wettability and ensuring better adhesion and coating performance.
Provides outstanding water resistance, forming a durable hydrophobic layer that effectively protects materials from moisture penetration.
Enhances abrasion and wear resistance, helping to extend the service life and durability of treated substrates.
Serves as a reliable catalyst in organic synthesis, contributing to improved reaction efficiency and process stability.
The molecular formula of potassium methylsilanetriol is CH₃K₃O₃Si (or written as C₆H₆K₂O₃Si), with a molecular weight of approximately 208.41. It typically exists as a colorless, transparent liquid with a solid content generally not less than 40%, a density of approximately 1.3, and is miscible with water, forming a strongly alkaline solution.
Potassium methylsilanetriol is primarily used as a surface treatment agent and catalyst. It improves the wettability, water resistance, and abrasion resistance of materials. Specific applications include:
as a penetrating waterproofing agent for waterproofing and moisture-proofing building materials such as concrete, masonry, and gypsum products; as a catalyst in organic synthesis; and as a hydrophobic additive in cultural relic restoration, wood treatment, and water-based coatings.
