Product Details
Introduction
3-Isocyanatopropylmethyldimethoxysilane is a uniquely structured and versatile organosilicon coupling agent that has the ability to simultaneously provide organic reactivity (via –NCO groups) and modify inorganic interfaces (via silanols generated by hydrolysis). It plays a key role in coatings, adhesives, sealants, and a variety of composite materials.

Application
1. Mainly used to treat the surface of inorganic, organic and metal materials, so that they have good adhesion with different materials to improve the comprehensive performance of materials or products.
2. Can react with amines, hydrogen azide and phosphate to obtain silane coupling agents containing urea, azide and phosphate groups.
3. Can be used as a tackifier for room temperature vulcanized silicone rubber to improve the bonding strength of rubber to the substrate.
4. Can be used as an organic polymer modifier to achieve chemical modification, and can also be used as a crosslinker and tackifier for coatings.
