Silane Coupling Agent Selection Guide

Silane Coupling Agent Selection Guide: Find the Right Silane Coupling Agent for Your Application

Silane coupling agents are used to improve the adhesion of materials, such as polymers, metals, and ceramics. This page provides a guide to selecting the right silane coupling agent for your application.

The rate of hydrolysis of silane coupling agents depends on the hydrolyzable functional group Si(OR)3, while the reactivity with organic polymers depends on the organic functional group – Y. Therefore, it is important to choose the right silane coupling agent for the different substrates or objects to be treated. The following table can help you to make the right choice of silane coupling agent:
