Shin‑Etsu KBM‑1003 Silane Coupling Agent 1 kg Vinyltrimethoxysilane for Resin–Inorganic Adhesion

About Shin-Etsu KBM-1003 Silane Coupling Agent

OVERVIEW:

Shin-Etsu KBM-1003 is an organofunctional silane coupling agent designed to improve adhesion between organic polymers and inorganic materials. It features an amino functional group, enabling chemical interaction with a variety of resin systems such as epoxies, polyurethanes, and phenolics. The silane moiety forms durable siloxane bonds with inorganic surfaces such as glass, metal, ceramics, and mineral fillers. KBM-1003 is commonly used to enhance bonding performance, chemical resistance, and mechanical properties in coatings, adhesives, sealants, and composite materials.

KEY FEATURES:

Adhesion Enhancement
Promotes strong bonding between organic resins and inorganic substrates, improving structural integrity and durability.

Amino Functional Group
Compatible with a broad range of resin systems including epoxies, polyurethanes, acrylics, and phenolics.

Moisture Resistance
Forms stable siloxane bonds that enhance water and chemical resistance of the bonded interface.

Surface Modification
Can be used as a surface treatment to impart improved adhesion and moisture resistance to various materials.

Versatile Functionality
Applicable as a coupling agent, adhesion promoter, or formulation additive across diverse industrial applications.

APPLICATIONS:

• Adhesives and Sealants – Improves adhesion to inorganic surfaces, enhancing bond strength and durability in high-performance adhesive and sealant systems.

• Coatings and Paints – Enhances adhesion to glass, metal, and mineral substrates, improving coating durability and resistance to moisture and weathering.

• Composite Materials – Promotes better bonding between resins and fillers or reinforcements, supporting improved mechanical properties.

• Glass and Ceramics Treatment – Applied as a primer or surface modifier to improve compatibility with organic coatings and adhesives.

• Electronics and Electrical Applications – Used in encapsulants and potting compounds to improve adhesion and reduce moisture ingress.

PACKAGING:

Shin-Etsu KBM-1003 is typically supplied in sealed containers such as 1kg bottles, 15kg pails, or 200kg drums, depending on regional availability and distributor offerings.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean substrate surfaces to remove oils, dust, and oxides to ensure optimal bonding.

• Application: Apply KBM-1003 as a primer, surface treatment, or formulation additive. Dilution with suitable solvents may be required for surface treatments.

• Curing: Allow treated surfaces adequate time for hydrolysis and condensation reactions before applying subsequent layers or assembly.
