PRODUCT DESCRIPTION
LOCTITE® Product 5920 is a one component, room temperature curing RTV silicone non-sag paste formulated for low volatility applications, as in oxygen sensor equipped General Motors’ engines.  Good for applications up to 350°C.

TYPICAL APPLICATIONS
This product is used to fill voids and irregularities in surfaces for a positive seal.   It adheres to metal, glass, natural and synthetic fibres, wood, ceramics, other silicone rubbers, pointed surfaces and many plastic substrates.   Product 5920 can be used on all assemblies where an engine manufacturer recommends room temperature vulcanising (RTV).  It is also used for electrical insulating applications.
