USi-2H22 — 2-(3,4-Epoxycyclohexyl)ethyltriethoxysilane
High-Performance Epoxy-Functional Organosilane for Enhanced Adhesion and Compatibility
CAS No.: 10217-34-2
Molecular Weight: 288.46
Synonyms: Triethoxy[2-(7-oxabicyclo[4.1.0]hept-3-yl)ethyl]silane
📄 Product Description
USi-2H22 is an epoxy-functional organosilane designed to enhance adhesion and compatibility between organic polymers and inorganic substrates:
- Epoxy group → reacts with resins (epoxy, PU, acrylic, etc.)
- Triethoxysilane group → hydrolyzes and bonds to glass, metal, minerals, and fillers
✅ Ideal for applications requiring improved moisture resistance, mechanical strength, and durability
✅ Suitable for a wide range of industries including composites, coatings, sealants, and foundry resins(High-resolution chemical structure available upon request – features cycloaliphatic epoxy ring linked to hydrolyzable triethoxysilane)
