  • Applications

    Silanetriol, 1-methyl-, potassium salt (1:?); CAS 31795-24-1 is a silicon-containing intermediate used in the synthesis of silicone polymers and resins. It commonly acts as a source of silanol/silanolate groups in sol-gel processes for coatings and adhesives, enabling the formation of silicon-oxygen networks. Because it is a methyl-substituted silanetriol salt, it can function as a crosslinking agent in coating, ink, and adhesive formulations, improving network connectivity and adhesion. It also serves as a building block for silicone-based binders used in electronics encapsulation and protective coatings. Real-world use cases are typically evaluated within regulatory and formulation limits.
