Description

3-Isocyanatopropylmethyldiethoxysilane, ChangFu? NCO23 is an isocyanate silane monomer with hydrolysable alkoxy groups. The structure makes it significantly useful for adhesion promotion and surface modification. Therefore, it has been employed as a silane coupling agent in the production of silicone based polymers such as coatings and sealants.

Features

• Highly reactive functional silane.

• Excellent coupling agent and adhesion promoter for polymers and inorganic substrates.

• Especially workable for MS polymers formulation.

About ChangFu Isocyanate Silanes

Changfu Chemical provides a range of high purity isocyanate functional silanes through non-phosgene synthesis method. Through the practice of green chemistry, Changfu Chemical is proud to adopt a green production process to manufacture these isocyanate silanes, eliminating the use of highly toxic and hazardous phosgene, and the production of corrosive byproduct, hydrogen chloride. As to the applications, ChangFu isocyanate silane coupling agents not only have the reaction characteristics of isocyanate functional group and can react with most hydrogen containing compounds, but also significantly improve the adhesion of polysiloxanes.
