WACKER SilGel® comprises highly transparent, silicone rubber compounds that cure to form silicone gels. They stand out due to their low viscosity and strong inherent tack, often rendering a primer or adhesion promoter superfluous. All products can be fully automatically processed in mixing and metering units, and are ideal for efficient mass production.

WACKER SilGel® products are addition-curing, RTV-2-silicone elastomers that cure both at room temperature and at higher temperatures.
