Loctite Retaining

Further Information

Last Modified: 22nd Apr 2016

Retaining compounds from Loctite secure bearings, bushes and cyclindrical parts into housings or onto shafts. When it is applied as a liquid, they form a 100% contact between mating metal surfaces which eliminates the need for expensive replacement parts, time consuming machining or the use of mechanical methods.

Advantages of Loctite Retaining compounds compared to traditional assembly methods:

  • High-strength products are able to carry high loads
  • It fills all voids which then prevents corrosion, as well as fretting
  • 100% contact means that load and stress will be distributed well over the joint

Key factors to consider when choosing the right compound:

  • The gap size between parts - low viscosity retaining compounds are suitable for gaps up to 0.15mm, whilst for gaps bigger than 0.15mm, retaining compounds with higher viscosities must be used
  • Temperature resistance - some applications require certain temperature resistance
  • Bond strength - If you require a permanent bond use a high strength retaining compond and choose a medium strength product if parts need to be taken apart due to maintenance issues
  • Cure speed - some applications require fast cure speeds to optimise production rates, whilst other applications need slower cures so that it is possible to make adjustments after the parts are assembled

Surface preparation is extremely important in order to successfully use these adhesives.
