Material Notes:
LOCTITE® 5920™ is a moisture-curing, non-corrosive silicone. The thixotropic nature of LOCTITE® 5920™ reduces the migration of liquid product after application to the substrate. It has been designed specially for gasketing and sealing applications where excellent temperature resistance is required. It is also used for electrical insulating applications. This product is suitable for high temperature applications.
