Features and Specifications

DOWSIL 3 4222 Dielectric Firm Gel Kit – Two part, translucent green dielectric gel offering fast room temperature cure and primerless adhesion for various applications.

DOWSIL 3 4222 Dielectric Firm Gel is a two part, translucent green gel designed for fast room temperature curing, eliminating the need for ovens or elevated temperatures in many cases. The unique color change from a mixture of blue and yellow components to green upon mixing provides visual confirmation of proper mixing ratios (1:1), minimizing the risk of application errors. This self indicating feature simplifies application and ensures consistent performance.

The gel exhibits excellent adhesion properties, often eliminating the need for a primer, and provides cushioning, self healing, and resilient characteristics once cured. These properties make it particularly well suited for use with sensitive components that require protection and stress relief. Furthermore, it serves as an effective electrical insulator, safeguarding circuits and interconnections. For optimal results, degassing under vacuum (above 28 inches Hg, or 10 20mm Hg) may be beneficial to remove air pockets and ensure a void free, protective layer. Cure time is approximately 30 minutes at 25°C, with the option of accelerated curing through the application of heat.

Key Features:
• Two part, self indicating gel (color change upon mixing)
