Vinyltrimethoxysilane CAS No. 2768-02-7
Vinyltrimethoxysilane CAS No. 2768-02-7 (VTMS) is a clear, colorless liquid with a mild, pleasant odor. It is a versatile silane coupling agent that can be used to modify the surface properties of a variety of materials, including plastics, metals, and ceramics. VTMS is also used in the production of silicones and other polymers.
VTMS is a trifunctional silane, which means that it has three reactive silicon-oxygen bonds. These bonds can react with the hydroxyl groups on the surface of a material, forming a strong, covalent bond. This bond helps to improve the adhesion of the material to other materials, such as paints, adhesives, and coatings.
VTMS is also a good hydrophobe, meaning that it repels water. This property makes it useful for waterproofing materials, such as wood, concrete, and fabrics. VTMS can also be used to improve the wettability of materials, which can be useful for applications such as printing and coating.
VTMS is a safe and effective silane coupling agent that can be used to improve the properties of a variety of materials. It is available in a variety of grades, including technical grade, reagent grade, and analytical grade. VTMS is typically used in concentrations of 1-10%.
Safety Information
VTMS is a low-toxicity material. However, it is important to take precautions when handling VTMS, as it can cause irritation to the skin, eyes, and respiratory system. It is also important to avoid skin contact with VTMS, as it can cause a rash. If VTMS comes into contact with the skin, wash the area with soap and water immediately. If VTMS gets into the eyes, flush them with water for at least 15 minutes and seek medical attention. If VTMS is inhaled, move to fresh air and seek medical attention if breathing becomes difficult.
Disposal Information
VTMS can be disposed of by incineration or by sending it to a hazardous waste disposal facility. It is important to check with local regulations to determine the proper method of disposal.
