USi-O401 — Vinyl Silane Oligomer
Low-VOC, High-Performance Adhesion Promoter for Polymer Composites
Equivalent to: Degussa (Evonik) DYNASYLAN® 6490
📄 Product Description
- Chemical Name: Vinyl Silane Oligomer
- Appearance: Colorless transparent liquid
- Key Innovation: Oligomeric structure with reduced volatility and lower VOC emissions vs. monomeric vinyl silanes (e.g., VTMS, VTES)
- Function: Acts as a molecular bridge between inorganic fillers and organic polymers, enhancing interfacial adhesion, mechanical strength, and moisture resistance
✅ Ideal for wire & cable, flame-retardant composites, and crosslinked polyolefins
✅ Safer processing due to high flash point and low methanol release during hydrolysis(Molecular structure available upon request – features vinyl-functional oligosiloxane backbone with hydrolyzable alkoxy groups)
📊 Typical Technical Data
⚠️ The following values are typical and provided for reference only. Not to be used for specification or quality acceptance without prior written confirmation from our technical team.
Parameter Specification Appearance Colorless transparent liquid Density (20°C) 1.080 ± 0.010 g/cm³ Specific Gravity (20°C) 1.4200 ± 0.0050 Viscosity ≤ 5 mPa·s (very low, fluid-like) 💡 Note: The dual density values reflect different measurement standards; please clarify application context with our technical team.
🌐 Applications
USi-O401 is engineered for demanding composite and polymer applications:
🔌 Wire & Cable Industry
- Coupling agent for ATH (aluminum trihydrate) and MDH (magnesium dihydroxide) in EVA, PE, and EPDM insulation/jacketing
- Enables higher filler loading → improved flame retardancy without sacrificing flexibility
🏗️ Flame-Retardant Composites
- Enhances dispersion and bonding of mineral fillers in thermoplastics and elastomers
- Reduces water sensitivity of final products
♻️ Environmental & Safety Advantages
- >70% lower methanol (VOC) emission during hydrolysis compared to monomeric vinyltriethoxysilane
- High boiling point & flash point → safer handling in high-temperature extrusion and mixing processes
📦 Packaging
- 20 kg plastic pail
- 190 kg steel/plastic drum
- 950 kg IBC tote
(All containers are sealed, labeled, and suitable for industrial transport)
🛡️ Safety & Storage
- Flammable liquid – keep away from heat, sparks, and open flame
- Store in original, tightly closed containers at ≤ 35°C
- Shelf Life: 12 months from production date under recommended conditions
- Always consult the latest Safety Data Sheet (SDS) before handling
→ Available at: www.usi-chemical.com or upon request - Use appropriate PPE: gloves, goggles, and ventilation as indicated in SDS
