How to Use Methyl MQ Resin in Thermally Conductive Potting Compounds

Methyl MQ resin is primarily used as a reinforcing and modifying agent in thermally conductive potting compounds, significantly improving the mechanical strength, transparency, and high-temperature resistance of the compound. The following are specific application methods:

1. As a Reinforcing Material

Function: Added to highly transparent silicone gel or liquid silicone rubber, the reinforced compound is colorless, transparent, and has high mechanical strength.

Application Scenarios: Suitable for shell-less potting compounds of semiconductor components, providing excellent insulation and moisture resistance.

2. As an Adhesion Promoter

Function: Used as an adhesion promoter when bonding inorganic and organic materials, improving interfacial bonding strength.

Application Scenarios: Used in the surface treatment of silicone pressure-sensitive adhesives and mobile phone buttons.

3. As a Modifying Agent

Boron Modification Application: By chemically modifying MQ silicone resin containing silanol groups with boric acid or borate esters, a high-temperature, high-thermal conductivity boron-modified organosilicon epoxy potting compound can be prepared.

Performance Improvement: The modified potting compound has a water absorption rate of less than 0.1%, significantly improving moisture resistance and making it suitable for high-temperature environments such as ceramic-based printed circuit boards.
