Product Introduction
Momentive INVISISIL™ RTV6136-D1 and RTV6139-D1 are two-component, low-viscosity silicone gels that cure into soft, gel-like elastomers with superior tear resistance compared to conventional silicone gels. Engineered for E/E and HEPA applications, these gels offer fast room-temperature curing, primerless adhesion, low shrinkage, and stable performance across wide temperature ranges. Available in clear and colored versions, they support applications requiring visual inspection and rework capability.
