SYLGARD™ 527 Silicone Dielectric Gel is a two-part, 1:1 mix ratio silicone gel designed for sealing and protecting PCB system assemblies, particularly those with delicate components. It offers low viscosity for good flow, room temperature or heat-accelerated curing, and availability in clear or red color. This gel provides excellent dielectric properties, stress relief, and self-healing characteristics after curing.
