|Anaerobic adhesives are widely used as formed-in-place gaskets that produce leak-proof seals between mating flanges, preventing leakage of moisture, gases, fluids or contaminants.
Gaskets are critical components that must perform under extremely difficult conditions. As the last line of resistance between interior and exterior, hot and cold, or wet and dry, they must withstand all these opposite poles, however great the differences. What is more, they must be absolutely reliable and have the longest possible service lives. Wacker Silicones has developed a series of technologies called formed-in-place gaskets (FIPG), compressive or "cured-in-place" gaskets (CIPG), and liquid-injected seals (LIS). The automotives and electronics sectors both include highly specialized applications that make extreme demands on the sealing materials used. They include engine gaskets, control unit gaskets, electronic encapsulation and special elements for decoupling noise and vibrations. Silicones are injected into the products to create the gasket. Potential applications in the building industry are window and door installations, as well as any product or material that penetrates the building envelope.
The technology is well developed in the automotive industry and has found numerous applications where temperature, fluid, and pressure extremes provide challenges to gasket reliability. There are no current applications in the residential building industry.
