Dimethylmethoxy-N-Propylsilane

Description:

Dimethylmethoxy-N-propylsilane, with the CAS number 18182-14-4, is an organosilicon compound characterized by its silane structure, which includes a silicon atom bonded to organic groups. This compound typically features two dimethyl groups and a methoxy group attached to the silicon, along with a propyl group. It is a colorless to pale yellow liquid with a low viscosity, making it suitable for various applications in the chemical industry. Dimethylmethoxy-N-propylsilane is known for its ability to act as a coupling agent, enhancing adhesion between organic materials and inorganic substrates. It is also utilized in the formulation of sealants, coatings, and adhesives due to its favorable properties, such as moisture resistance and thermal stability. Additionally, this silane can participate in hydrolysis reactions, leading to the formation of silanol groups, which can further polymerize to create siloxane networks. Safety data sheets should be consulted for handling and storage guidelines, as it may pose health risks if inhaled or ingested.

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.
