Base Silicone Resin: Density 1.05-1.15 g/cm³

Component Specifications

Definition

Base silicone resin is a crosslinkable organosilicon polymer with a three-dimensional network structure, typically containing siloxane (Si-O-Si) backbones and reactive functional groups such as hydroxyl or alkoxy. It serves as the fundamental building block for producing powder silicone resins through further polymerization or curing processes. The resin exhibits excellent thermal stability, weather resistance, and dielectric properties.

Working Principle

The resin is synthesized via hydrolysis and condensation of organosilicon monomers (e.g., methyltrimethoxysilane) under controlled pH and temperature. The resulting polymer chains form a network that can be further cured to achieve desired mechanical and chemical properties.

Materials

Polysiloxane with methyl and phenyl groups; typical molecular weight 2000-5000 g/mol; viscosity 500-2000 mPa·s at 25°C.
