Retaining Compounds for Metals
Retaining compounds fill the space between unthreaded metal parts to hold them in place and dampen vibration. They are anaerobic, which means they remain fluid until they fill the empty space between metal surfaces and then cure in the absence of air, allowing them to seep into small crevices before bonding. Retaining compounds help reduce friction between tight fitting parts to evenly distribute load, reduce wear, and prevent the production of small particles caused by abrasion. They are often used in automotive or heavy machinery applications to hold bearings inside their housing or mount gears and pulleys onto shafts.
