Siwin-AL121 is called 3-Isocyanatopropylmethyldimethoxysilane.
It is a bifunctional silane with isocyanate and alkoxy groups.
The dimethoxy group will form a reactive silanol or -OH group after hydrolysis, and then show a good adhesion ability to various inorganic materials or surfaces.

Silane Siwin-AL121
Isocyanatopropylmethyldimethoxysilane
Description
Siwin-AL121 is called 3-Isocyanatopropylmethyldimethoxysilane. It is a bifunctional NCO silane with isocyanate and alkoxy groups. The dimethoxy group will form a reactive silanol or -OH group after hydrolysis, and then show a good adhesion ability to various inorganic materials or surfaces. Siwin-AL121 can hydrolyze at a smooth level and stay stable after hydrolysis.
