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.
