Product Introduction

Silane Coupling Agent KH-560 | Epoxy Functional Silane Adhesion Promoter|CAS 2530-83-8

1. Product Introduction

Silane Coupling Agent KH-560, chemically named 3-Glycidoxypropyltrimethoxysilane (CAS 2530-83-8), is a high-purity epoxy-functional silane coupling agent with excellent interfacial modification performance. It appears as a colorless and transparent oily liquid at room temperature, containing active epoxy functional groups and hydrolyzable trimethoxy groups in its molecular structure. Unlike conventional amino silane products, KH-560 features mild reaction activity, low yellowing tendency and excellent compatibility with epoxy resin systems, making it a specialized modifier for high-end composite materials and electronic packaging materials.

As a mainstream high-performance silane coupling agent in the global fine chemical industry, KH-560 can effectively bridge inorganic substrates and organic polymer materials. Its epoxy groups can stably react with amino, hydroxyl and carboxyl groups in resins, while methoxy groups hydrolyze to bond with the surface of glass, metal, silica and mineral fillers. This dual-reaction mechanism significantly improves interfacial adhesion, mechanical strength, water resistance and thermal stability of composite products. Our industrial-grade Silane Coupling Agent KH-560 boasts high purity (≥98%), low impurity content, stable batch consistency and ultra-low volatile residue, fully compliant with international electronic grade, coating and composite material production standards.

3. Product Features & Applications

Core Product Features

Professional epoxy functional modification: KH-560 is a dedicated epoxy-based silane coupling agent with highly active glycidoxy groups. It can undergo stable cross-linking reactions with epoxy resins, phenolic resins, polyurethanes and other polymer systems, forming firm chemical bonding interfaces and thoroughly solving the problem of poor adhesion between inorganic fillers and organic resins.
Ultra-low yellowing & high transparency: Different from traditional amino silane coupling agents that are prone to yellowing, KH-560 has excellent anti-yellowing performance and high light transmittance. It will not cause discoloration or chromatic aberration of transparent materials and high-gloss coatings, fully meeting the production requirements of high-end optical and cosmetic-grade materials.
Excellent water resistance & thermal stability: After hydrolysis and cross-linking film formation, it forms a dense hydrophobic interface layer, which significantly improves the water soaking resistance, moisture resistance and high-temperature aging resistance of composite materials. It effectively avoids interface peeling and strength attenuation in humid and high-temperature working environments.
Mild reaction & wide compatibility: Featuring moderate hydrolysis speed and mild reaction activity, KH-560 will not cause excessive curing or system instability. It has excellent compatibility with solvent-based, water-based and solvent-free resin systems, suitable for diversified industrial formula upgrading and continuous production processes.
Improve mechanical & insulating properties: It can significantly enhance the tensile strength, impact toughness and bonding durability of composite materials. Meanwhile, it optimizes the internal compactness of electronic packaging materials and improves electrical insulation performance, making it ideal for electronic and electrical industry applications.

Main Application Fields

Electronic Packaging & Electrical Materials: Widely used as surface modifier and adhesion promoter for epoxy electronic packaging materials, copper-clad plates, insulating adhesives and electronic potting glues. It improves the bonding strength between resin and inorganic fillers, enhances product insulation, moisture resistance and thermal stability, and ensures long-term stable operation of electronic components.
High-End Industrial Coatings: Applied in epoxy anti-corrosion coatings, transparent finishing coatings, automotive coatings and architectural waterproof coatings. It optimizes the adhesion between coating film and metal, glass and concrete substrates, prevents coating peeling and blistering, and improves coating weather resistance and anti-corrosion service life.
Glass Fiber Reinforced Composites: Used as glass fiber surface treatment agent for FRP composite materials. It improves the interface bonding between glass fiber and epoxy resin matrix, enhances the overall mechanical strength and corrosion resistance of FRP products, and is widely used in building reinforcement, industrial equipment and new energy composite parts.
Inorganic Filler Surface Modification: Suitable for surface activation treatment of silica, talc powder, calcium carbonate, aluminum hydroxide and other mineral fillers. It improves filler dispersion in organic resins, reduces system viscosity, increases filler loading capacity, and reduces production costs while maintaining product mechanical properties.
Adhesive & Sealant Industry: Added to epoxy structural adhesives, high-temperature resistant sealants and transparent glue products. It improves the bonding durability of adhesives on inorganic surfaces, enhances high-temperature resistance and water resistance of adhesive joints, and meets the bonding requirements of high-standard industrial scenarios.

4. Packaging, Storage & International Sea Shipping
