INVISISIL™ RTV6139-D1 is a two-component, blue transparent silicone gel formulated to cure into a soft, high-strength gel elastomer. Designed for demanding E/E and HEPA applications, the gel provides superior tear resistance, fast room-temperature curing, and strong adhesion without primers. Its low shrinkage, low volatility, and broad thermal stability make it suitable for encapsulation tasks requiring durability and easy inspection.
