In the fields of optical encapsulation, LED packaging, and high-refractive-index adhesives, both the optical properties and thermal stability of materials are indispensable. IOTA 252 Methyl Phenyl Vinyl Silicone Oil, with its unique phenyl structure and high refractive index characteristics (1.50–1.54), provides a key material for the optical and electronic packaging industries, combining optical transparency, heat resistance, and reactivity.
Core Performance Advantages:
High Refractive Index: Refractive index up to 1.54, suitable for LED packaging, optical lenses, and optical coupling materials.
High Heat Resistance: Phenyl structure imparts excellent thermal stability, with long-term use temperatures exceeding 200°C.
Reactive Design: Dual vinyl end groups enable efficient crosslinking and curing via hydrosilylation reactions.
Excellent Compatibility: Compatible with various phenyl silicone rubbers, silicone resins, and filler systems.
Technical Specifications:
| Viscosity (mm²/s) | Refractive Index (20°C) | Vinyl Content (wt%) | Appearance |
|---|---|---|---|
| 100 | 1.50 ± 0.01 | 3.1 ± 1 | Colorless transparent oily liquid |
| 1000 | 1.52 ± 0.01 | 1.5 ± 0.2 | Colorless transparent oily liquid |
| 3000 | 1.53 ± 0.01 | 0.7 ± 0.1 | Colorless transparent oily liquid |
| 5000 | 1.54 ± 0.01 | 0.4 ± 0.1 | Colorless transparent oily liquid |
Note: All specifications have a specific gravity of 1.05–1.10 and a flash point above 100°C.
Main Application Areas:
Optical Encapsulation Materials: LED packaging adhesives, optical lens adhesives, optical fiber couplers.
High-Temperature Curing Adhesives: Heat-resistant potting compounds, semiconductor packaging materials.
High Refractive Index Coatings: Optical anti-reflection films, protective coating base materials.
Specialty Silicone Rubbers: Active diluent for high-transparency phenyl silicone rubbers.
Usage Recommendations:
This product can be used as the vinyl component in addition-cure phenyl silicone rubbers. It is recommended to use it in combination with hydrogen-containing silicone oil and platinum catalysts for curing at low to medium temperatures. It can also serve as an active diluent for vinyl phenyl silicone resins to adjust system viscosity without affecting final performance.
Packaging and Storage:
Available in 1 kg, 5 kg, and 25 kg packaging. Store in a cool, dry place, protected from light and sealed. Recommended storage temperature not exceeding 30°C.
