Silane Coupling Agents Application Guide

Best results are obtained in an unsaturated polyester-based FRP by using a vinyl – or methacryloxy-containing silane as the silane coupling agent.

Silane Coupling Agents

What are Silane Coupling Agents? Silane coupling agents are compounds whose molecules contain functional groups that bond with both organic and inorganic materials. A silane coupling agent acts as a sort of intermediary which bonds organic materials to inorganic materials.

Silane Coupling Agent

There are three basic approaches for using silane coupling agents. The silane can be used to treat the surface of the inorganic materials before mixing with the organic resin or it can be added directly to the organic resin or holistic mixing (in organic-inorganic mixture).

Silane Coupling Agents

Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.

How Silane Coupling Agents Become Secret Weapons in

In particular, KH-570 and KH-560 are two types of silane coupling agents that, when mixed in a 3:2 ratio, can significantly enhance adhesion to substrates. KH-570 has methacryloxy groups, while KH-560 contains glycidoxy groups.
