Silico® Phenyl Silicone Resins
Phenyl Silicone Resins are high-performance organosilicon materials characterized by the presence of phenyl groups (–C₆H₅) in their molecular backbone. These resins provide excellent thermal stability, enhanced low-temperature flexibility, and superior electrical insulation compared to traditional methyl silicone resins. They are widely used in electronic encapsulation, protective coatings, adhesives, and high-temperature insulating materials.
Silico® offers a wide range of phenyl silicone resins, including various structural and functional types to meet diverse application needs.

Types of Phenyl Silicone Resins
| Category | Description | Typical Applications |
|---|---|---|
| Methyl Phenyl Silicone Resin | Contains both methyl and phenyl groups for balanced heat resistance and film-forming ability. | Heat-resistant coatings, electrical insulation |
| High-Phenyl Silicone Resin | High phenyl content (>40%) provides excellent low-temperature flexibility and dielectric stability. | Electronic potting, aerospace encapsulation |
| Phenyl Hydrogen Silicone Resin | Contains reactive Si–H groups for crosslinking and modification. | Adhesives, coating additives |
| Phenyl Vinyl Silicone Resin | Offers UV or thermal curability due to vinyl groups, along with phenyl-enhanced properties. | UV-curable coatings, LED encapsulants |
| Phenyl MQ Silicone Resin | Built from M and Q units with phenyl groups, combining rigidity with optical and thermal stability. | Optical coatings, adhesives, conformal coatings |
| Modified Phenyl Silicone Resins | Includes epoxy-, acrylic-, or polyester-modified phenyl silicone resins for enhanced adhesion or mechanical performance. | High-performance coatings, hybrid adhesives |
