Product Introduction
Silane Coupling Agent (Code:KH-172) | Vinyl Tris(2-methoxyethoxy) Silane|CAS 1067-53-4
1. Product Introduction
KH-172, also known as Vinyl Tris(2-methoxyethoxy) Silane, is a high-performance water-soluble vinyl-functional silane coupling agent with the CAS number 1067-53-4. It appears as a colorless and transparent oily liquid at room temperature, featuring unique vinyl active groups and hydrolyzable methoxyethoxy groups in its molecular structure. Different from conventional silane products, KH-172 boasts excellent water solubility, mild hydrolysis performance and low volatility, avoiding excessive volatilization and unstable bonding issues during industrial application.
As a versatile organosilicon adhesion promoter and crosslinking modifier, KH-172 silane coupling agent acts as a critical interfacial bridge between inorganic fillers and organic polymer materials. It can form stable chemical bonds with glass fiber, silica powder, clay, ceramic and other inorganic substrates, as well as cross-linked polyethylene, EPDM rubber, unsaturated polyester, EVA and other polymer resins. It significantly improves the mechanical strength, waterproof performance, wet electrical insulation and aging resistance of composite materials. Widely recognized in the global market, KH-172 is a core modifier for wire and cable crosslinking, rubber reinforcement, functional coating and inorganic filler surface treatment industries.

- Dual reactive molecular structure: Contains active vinyl groups and hydrolyzable methoxyethoxy groups, realizing efficient crosslinking reaction and tight interfacial bonding between inorganic fillers and organic polymers, solving material compatibility and interface peeling problems.
- Low volatility & high stability: High boiling point and low volatilization loss during high-temperature processing, ensuring stable modification effect and no environmental pollution in continuous industrial production.
- Wide compatibility & cost-effective: Perfectly compatible with polyolefin, rubber, polyester and various resin materials, with low additive dosage and obvious performance improvement, suitable for large-scale industrial mass production.
Main Application Fields
- Wire & Cable Industry (Core Application): Special crosslinking and modification agent for water-crosslinkable PE cables and EPDM rubber cables. It effectively enhances wet insulation performance, heat resistance, tensile strength and aging resistance of cable insulation layers, ensuring long-term safe operation of outdoor and humid-environment cables.
- Rubber & Polymer Modification: Used for surface treatment of clay, silica and other inorganic fillers filled in polyethylene, polypropylene and EPDM rubber. It improves filler dispersion, enhances mechanical toughness and waterproof performance of rubber and plastic products.
- Composite Materials Industry: Applied in glass fiber reinforced unsaturated polyester composite materials, improving interfacial bonding strength, reducing water absorption rate, and enhancing dry and wet mechanical stability of reinforced plastics.
- Functional Coatings & Adhesives: Serves as adhesion promoter for waterproof coatings, anti-corrosion coatings and industrial sealants, improving the bonding force between coating/adhesive and inorganic base materials, and strengthening weather resistance and water resistance of finished products.
- Electronic & Electrical Industry: Used for surface moisture-proof and insulation treatment of electronic components, improving the stability and service life of electrical equipment in humid working conditions.
