Product Details
Introduction
Isobutyltrimethoxysilane is an organic silicon coupling agent, which contains both hydrophobic isobutyl and easily hydrolysed methoxy groups in its structure. This enables it to form a strong interface connection between organic and inorganic materials and is therefore widely used in composite materials, adhesives, coatings, sealants and other fields.
