The silane coupling agent treatment on the filler can provide better bonding of the pigment or filler to the resin, improved mixing, increased matrix strength and reduced viscosity of the uncured sealant or adhesive.

3、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.

4、Silane Coupling Agents

The general formula for a silane coupling agent typically shows the two classes of functionality. X is a hydrolyzable group typically alkoxy, acyloxy, halogen or amine.

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 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 Agent

Any silane coupling agent with three alkoxy groups on silicon should bond equally well to an inorganic substrate, but matching of the organofunctional group on silicon with the polymer type of the resin to be bonded will dictate which silane coupling agent should be used in a particular application.

Explore silane coupling agent mechanisms and bonding agents: learn how silane/silicone agents enhance adhesion in composites, coatings, fillers, and improve strength under wet/dry conditions.

Silane Coupling Agents

This property enables silane coupling agents to function as intermediaries in bonding organic materials to inorganic materials, which normally tend not to bond with each other.

Silane Coupling Agent

By mixing a slurry of the inorganic materials in a dilute solution of the silane coupling agent, a highly uniform and precise surface treatment of the inorganic material can be obtained. A high shear, high speed, mixer is used to disperse the silane coupling agent into the inorganic materials.
