Shin Etsu Kbm403 Silane Coupling Agent Water- Heat- Weather-Resistant Adhesion-Enhancing Paint

Shin Etsu Kbm403 Silane Coupling Agent Water- Heat- Weather-Resistant Adhesion-Enhancing Paint

Basic Properties

KBM-403 is an epoxy-functional silane coupling agent manufactured by Shin-Etsu, with the chemical name ​​3-Glycidoxypropyl trimethoxysilane​​ (CAS No. ​​2530-83-8​​). Its molecular weight is ​​236.3​​, and it excels in enhancing adhesion between inorganic and organic interfaces, making it ideal for composites, coatings, and surface modification.

Product Introduction

KBM-403 leverages both epoxy and methoxysilane groups to dramatically improve the bonding strength between resins/rubbers and inorganic substrates (e.g., glass, metals, fillers). Its groups react faster than ethoxy silanes, rapidly forming stable bonds with surface hydroxyl groups. The epoxy group is compatible with most thermoset/thermoplastic resins (e.g., epoxy, PU, acrylic), enabling versatile polymer applications.

Unique Features

1. ​High Reactivity​​: groups enable faster hydrolysis/condensation, ideal for high-speed production.

2. ​​Broad Compatibility​​: Epoxy groups participate in resin cross-linking, enhancing mechanical properties (e.g., tensile strength, water resistance).

3. ​​Thermal Stability​​: Boiling point up to ​​290°C​​, suitable for high-temperature processes.

Applications

• ​​Composites​​: Enhances interlaminar shear strength in glass/carbon fiber-reinforced epoxy.

• ​​Coatings​​: Adhesion promoter for anti-corrosion coatings on metals.

• ​​Rubber​​: Improves abrasion resistance and wet grip in silica-filled tires.

• ​​Electronics​​: Surface treatment for inorganic fillers in semiconductor encapsulants.
