Retaining

Loctite Retaining Compounds, an anaerobic adhesive, secure bearings, bushes and cylindrical parts into housings or onto shafts. They achieve maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion. Applied as a liquid, they form a 100 % contact between mating metal surfaces, eliminating the need for expensive replacement parts, time consuming machining or the use of mechanical methods. Loctite Retaining Compounds fill the inner space between components and cure to form a strong precision assembly.

Advantages of Loctite Retaining Compounds as compared to conventional assembly methods:

  • High-strength products can carry high loads
  • Fill all voids for fretting and corrosion protection
  • 100 % contact – load and stress is distributed evenly over the joint

Loctite Retaining Compounds fill the inner space between components and cure to form a strong precision assembly.

How to choosing the right Loctite Retaining compound
Gap size between parts

Typically, low viscosity retaining compounds (125 to 2,000 mPa•s) are used for gaps up to 0.15 mm. For gaps greater than 0.15 mm, retaining compounds with higher viscosities (>2,000 mPa•s) should be used.
Temperature resistance
Most Loctite® Retaining Compounds are capable of withstanding temperatures up to 150°C. For applications that require resistance to higher temperatures Henkel has developed a special range of retaining products that can withstand
Bond strength
A high-strength retaining compound is recommended for applications that require a permanent bond. If parts will need to be taken apart for maintenance, it is better to use a medium strength product because shear strength is lower.
Cure speed
Many production applications require retaining compounds with fast cure speed to optimize production rates. On the other hand, some applications call for a slower cure so that adjustments can be made after the parts have been assembled. Our range of Loctite® Retaining Compounds offers a wide choice of cure speed options.
