One of'his patented inventions was an unusual anaerobic-a chemical that remains in a liquid state while exposed to air but turns into a tough, binding solid in the absence of air. This chemical, which he called "Loctite," would lock
nuts and bolts against loosening from vibration. In the beginning; no one believed that a liquid could do the job that Loctite was claimed to do. But it did, and the result was phenomenal. Today Loctite offers a series of "amazing chemicals"that keep metal assemblies together. These compounds can and do replace lockwashers, gas~~ts, tape, rivets, screws, and other mee chanical fastenerS. The adhesives and sealants the company offers rely on the fourth generation of
