3-Mercaptopropyltriethoxysilane CAS No.14814-09-6

3-Mercaptopropyltriethoxysilane CAS No.14814-09-6 (MPTS) is a bifunctional organosilane that has a reactive organic mercapto group and a hydrolyzable inorganic methoxysilyl group. This makes MPTS a versatile coupling agent that can be used to improve the adhesion of a variety of materials.

MPTS is commonly used to improve the adhesion of elastomers to inorganic fillers, such as silica, clay, glass, mica, and talc. It is also used to improve the adhesion of plastics to metals, and to improve the water resistance of coatings.

In addition to its use as a coupling agent, MPTS is also used in a variety of other applications. For example, it is used in the production of photoresists, which are used in the manufacture of electronic devices. MPTS is also used in the production of catalysts, and in the treatment of wastewater.

MPTS is a safe and effective chemical that has a wide range of applications. It is a valuable tool for chemists and engineers who are looking to improve the performance of a variety of materials.

Safety Information:

MPTS is a flammable liquid and should be handled with care. It can irritate the skin and eyes, and it may be harmful if inhaled. If you come into contact with MPTS, wash the affected area with soap and water immediately. If you get MPTS in your eyes, flush them with water for at least 15 minutes and seek medical attention.
