Silanetriol, methyl-, triacetate

Description:

Silanetriol, methyl-, triacetate, with the CAS number 4253-34-3, is an organosilicon compound characterized by the presence of silicon, oxygen, and carbon atoms. This compound features a silanol group (Si-OH) that is further modified by three acetate groups (–OCOCH3) and a methyl group (–CH3). The presence of these functional groups imparts unique properties, such as potential reactivity in condensation reactions and the ability to form siloxane bonds. Silanetriols are generally known for their role in surface modification and as precursors in the synthesis of silicate materials. The acetate groups enhance the solubility of the compound in organic solvents, making it useful in various applications, including coatings, adhesives, and sealants. Additionally, the compound may exhibit hydrolytic stability, which is significant for its performance in moisture-rich environments. Overall, silanetriols like this one are valuable in materials science and chemical synthesis due to their versatile reactivity and functionalization potential.

Alkyl Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.
