Sometimes you need to apply an adhesive in spaces where there is no air to assist in drying the glue. Retaining compounds are multipurpose, high strength anaerobic adhesives (they don’t require air to harden). They can improve the axial strength of a component when applied at the joint. Because centrifugal force can pressure pulleys and gears to move on shafts, an application of a retaining compound between shaft and gear, for example, can provide extra hold and prevent slippage and wear. They are also used to fill the spaces between mechanical components, thereby reducing even the small movements that can lead to abrasion and damage.
