Joining adhesives from Henkel – Loctite and Omnifit
The adhesive manufacturer Henkel also produces joining adhesives under its Loctite and Omnifit brands, which are suitable for bonding components that are subject to special loads due to their high strength, among other things.
In the following article, we explain what joining adhesives are, what types there are, for which areas of application these anaerobic adhesives are used, which Omnifit and Loctite joining adhesives can be purchased online from the specialist wholesaler abovo and what advantages Loctite joining adhesives have.
What are adhesives?
Joining adhes ives are adhesives that are intended for joining different components together, whereby the joining adhesive usually fills gaps between these components.
As a rule, these are anaerobic adhesives that cure without oxygen in the adhesive joint. These adhesives remain liquid until they come into contact with active metal ions in the absence of air, i.e. the bonding of the components requires metal-to-metal adhesion.
Press-fit adhesives are therefore particularly suitable for the precision assembly of press-fit and insertion parts. However, they are also suitable for components installed in systems where strong vibrations occur and the ambient conditions are difficult.
After curing, adhesives form a strong bond and make it possible to transfer high loads. Due to the high strength of adhesives, they are particularly suitable for bonding components that rarely or never need to be dismantled.
Types of adhesives
Henkel offers adhesives with different properties. For example, there are high-strength joining adhesives or adhesives that can withstand particularly high temperatures(high-temperature resistant joining adhesives).
When selecting a suitable joining adhesive, you should consider, among other things, whether one or more of the following properties is/are relevant for the respective application and which joining adhesive has these properties:
- High strength
- High temperature resistance
- Fast curing
- Superior gap filling capacity
- Low viscosity
- Fluorescent formula
High-strength joining adhesives are used, for example, for constructions that are subject to high loads. High-strength adhesives are also used for components that are used in demanding environmental conditions. Another area of application is the bonding of components where only a limited bonding surface is available. Furthermore, these joining adhesives are suitable for demanding assembly processes where the focus is on sealed components and access is difficult.
High temperature resistant joining adhesives are particularly suitable for the MRO and automotive industries for applications with high ambient temperatures and thermal operation of components.
Areas of application for joining adhesives
Pressure-sensitive adhesives are used in a variety of applications, for example for various mechanical components, but also for shafts, bearings and cylinder liners.
The adhesives are used in the following industries, among others:
- Automotive industry
- Heavy machinery industry
- Aerospace industry
- MRO industry
Buy Loctite joint adhesive online
In the online store of the Swiss specialist wholesaler abovo offers various Loctite joining adhesives from Henkel:

In addition to the Loctite joining adhesives, abovo also offers the Omnifit 230M jointing adhesive from Henkel as well as Loctite SF 7200 for easy removal of old adhesive residues and Loctite SF 7063, which should be used to degrease and clean the surfaces before applying the adhesive.
Instructions for processing Loctite joining adhesive can be found on the Henkel website, whereby this processing should only be carried out by specialists and the appropriate joining adhesive must be selected depending on the joining method.
Advantages of Loctite joint adhesives
The Loctite range of joint adhesives has the following advantages:
- Higher strength with simpler and more cost-effective designs
- Less dependence on manufacturing tolerances
- Prevention of corrosion and fretting corrosion
- The load and stress distribution is even across the connection point
When Loctite jointing adhesives are combined with interference fits, the following advantages are achieved:
- The transmission of higher forces and better performance with existing geometry and design solutions
- The same performance with relaxed manufacturing tolerances
- Lighter construction and smaller parts
In addition, the use of Loctite joint adhesives can avoid the following problems that occur with conventional assembly methods:
- Feather key connections: These connections result in an uneven distribution of mass, which causes an imbalance that leads to vibrations at higher speeds.
- Wedge profiles, pins and tooth profiles: Here, stress peaks occur in the area of the spring due to the “notch effect”; in addition, high production costs are incurred.
- Clamping seat, interference fit, shrink fit and conical seat: In order to transmit the torque, these seats are dependent on friction. Friction, in turn, is determined by the surface finish, the material and the design. Furthermore, very tight tolerances are required in order to achieve a certain load capacity. This results in high manufacturing costs.
