Overview
Silane triol, with the molecular formula Si(OH)3, is a reactive silicon compound primarily used as an intermediate in the production of silicones and silane coupling agents. Its high reactivity makes it valuable in industrial applications where surface modification and adhesion promotion are required. Due to its instability, silane triol is often generated in situ rather than isolated. It plays a crucial role in forming siloxane bonds, which are foundational to silicone polymers and various industrial coatings.
Physical and Chemical Properties
Silane triol is a colorless liquid with a molecular weight of 79.10 g/mol. It is soluble in water and polar solvents, making it versatile for various chemical processes. The compound is highly reactive, particularly with moisture, leading to the formation of siloxanes through condensation reactions. Its density is approximately 1.2 g/cm³, though precise physical properties like melting and boiling points are less documented due to its tendency to polymerize or react under standard conditions.
Main Applications
Silane triol is predominantly used in the synthesis of silicones, where it acts as a building block for siloxane polymers. These polymers are essential in sealants, adhesives, and coatings due to their thermal stability and flexibility. Additionally, silane triol is employed in the production of silane coupling agents, which improve adhesion between organic and inorganic materials. This makes it valuable in composites, paints, and surface treatments for metals and glass.
Safety and Storage
Silane triol is corrosive and requires careful handling. Workers should use protective gloves, goggles, and ventilation to avoid skin contact and inhalation. It reacts vigorously with moisture and oxidizing agents, necessitating dry and inert storage conditions. Storage should be in tightly sealed containers, preferably under nitrogen or argon, to prevent polymerization or degradation. Spills should be neutralized with appropriate absorbents and disposed of according to local regulations.
B2B Procurement Guide
When procuring silane triol, B2B buyers should prioritize suppliers who provide comprehensive technical data, including purity levels and reactivity profiles. Due to its instability, batch testing and certificates of analysis are crucial. Pricing varies based on purity and quantity, so buyers should request quotations from multiple suppliers. Logistics should ensure moisture-free transport and storage to maintain product integrity. Long-term contracts may offer cost advantages for bulk purchases.
