Dow Corning 3-4207 Dielectric Tough Gel, 7.2kg Kit, Yellow/Blue

ID: DC3-4207X7.2KG Mfr ID: 3-4207-7.2KG
Manufactured by: Dow Corning
Dow Corning 3-4207 dielectric tough gel may lose adhesion. Full environmental exposure testing is recommended. For applications that require gels with added strength, there are tough or firm gel products. They can assist cost of ownership improvements due to their room temperature cure that requires no ovens though they can be heat accelerated if desired. These materials have enhanced chemical adhesion and cure slightly harder than standard gels, but may have limited applicability depending on processing conditions, device design, end-use environment and other conditions.

Gels are a special class of encapsulants that cure to an extremely soft material. Gels cure in place to form cushioning, self-healing, resilient materials. Cured gels retain much of the stress relief and self healing qualities of a liquid while providing the dimensional stability of an elastomer which is increasingly needed for delicate components.
