Product Description
Shin-Etsu KBM-303 Epoxy Silane Coupling Agent
Specialized chemical agent designed to enhance interfacial adhesion between organic polymers and inorganic materials in composite systems.
Chemical Composition
2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane (CAS 3388-04-3) featuring reactive methoxysilane and epoxy organic functional groups.
Technical Specifications
| Property | Value |
|---|---|
| Product Type | Silane |
| Kind | Epoxy Silane Coupling Agent |
| Boiling Point (°C) | 310 |
| Specific Gravity (25°C) | 1.06 |
| Refractive Index (25°C) | 1.448 |
| Molecular Weight | 246.400 |
Mechanism of Action
The methoxysilane group bonds to inorganic surfaces (glass, metals) while the epoxy group reacts with organic polymers (epoxy resins, rubbers), creating strong interfacial bonds that significantly improve mechanical strength in composite materials.
Performance Advantages
Fast Hydrolysis
group hydrolyzes faster than ethoxy alternatives, accelerating curing in humid conditions
Superior Stability
Epoxycyclohexyl group provides excellent hydrolysis resistance and thermal stability
Process Efficiency
Low viscosity facilitates easy blending and surface treatment applications
Industrial Applications
- Fiber-reinforced plastics and composite materials
- Industrial sealants and adhesive formulations
- Protective coatings and surface treatments
- Electronic encapsulants and PCB coatings
- Tire cord bonding and rubber reinforcement
