Dielectric Silicone Gel Potting Materials

Momentive’s dielectric silicone gel materials are extremely soft, lightly cross linked silicone polymers that provide good stress relief and self healing properties while maintaining dimensional stability and provide a tacky adhesion. These properties make the dielectric gels excellent candidates to consider for protection of fragile electronic components from moisture and the contaminants. Momentive offers a range of room temperature cure gels including one and two part products, and specialized grades that can help provide improved vibration dampening, very fast RT cure and UV activated cure.
