Henkel’s LOCTITE® polyurethane technology is highly effective for the running repair of conveyors belts and rubber parts such as liners in mills, pumps, feeding bowls, hoppers and chutes. 

Henkel and Covestro combine their strengths to promote e-mobility 

We have introduced new packaging to thwart those who seek to imitate their products.

The latest introduction from Henkel is another milestone for its LOCTITE® brand.  The company has developed a new range of Universal Structural Bonders whose many attributes have been achieved through new, patented hybrid technology. This innovative approach substantially extends the application scope of these adhesives which also afford improved health and safety benefits.

The general-purpose Universal Structural Bonders combine the qualities of different adhesives to achieve bond strength, fast fixture speed and durability.  They provide improved performance on a variety of substrates and the versatility to solve many more maintenance and repair challenges.  Formulated specifically for application in harsh factory and plant environments, they are effective in a wide variety of operating conditions, from temperature extremes to high vibration. 

The new LOCTITE® HY 4070 provides a good example of what these qualities...

Higher temperature and oil tolerance as well as improved performance on passive materials are the benefits of the latest generation of LOCTITE® retaining compounds from Henkel. These anaerobic adhesives are formulated to secure bearings, bushes and cylindrical parts into housings and onto shafts.  They are high-strength products that form 100% contact between mating metal surfaces so they can carry high loads and are particularly effective in combination with shrink- or press fits.

Two of the most popular products in this range are typical examples of the improved formulation.  LOCTITE® 638 and 648 are single component acrylic adhesives that are now able to tolerate minor surface contamination from various oils such as those used for metal cutting, lubrication, corrosion resistance and protection. This, together with their ability to withstand higher operating temperatures, considerably extends the application scope of these retaining compounds.

Both products...

More than 50 years ago, LOCTITE® introduced the world’s first ever anaerobic threadlocking adhesive. Despite the maturity of the technology, it has been continually developed to provide new benefits and the company now asserts that its latest generation threadlockers are ‘the best ever’.

Henkel’s LOCTITE® threadlocking adhesives prevent self-loosening and secure any threaded fastener against vibration and shock loads.  Many are easy-flowing liquids which completely fill the gaps between mating threads. When used to assemble threaded fasteners, LOCTITE® threadlockers permanently secure assemblies and eliminate fretting corrosion.

Two of the most popular products in this range – LOCTITE® 270 and 243 - exemplify the advances that have recently been made. LOCTITE® 270 is a high strength adhesive, ideal for permanent locking of assemblies that do not require regular disassembly for maintenance.  Its medium strength counterpart – LOCTITE®...

LOCTITE® 518 gasket sealant just gets better and better.  First introduced to overcome the problems associated with conventional pre-cut compression gaskets, this product has been continuously developed to increase its scope of application. 

This anaerobic adhesive can now cure through light surface contamination and works well on stainless steel and aluminium without an activator.  And it has also been made available in pen form that delivers the proven leak-fighting properties of LOCTITE 518 via a roller, making application easier than ever with no waste and less mess.

The major causes of failure and leakage of a compression gasket are poor surface contact, the tendency to relax under dynamic load and bolt hole distortion that cause it to crack and tear.  LOCTITE 518 is the ideal alternative as it fills all voids, resists high pressure and when fully cured maintains clamp load and prevents corrosion. 

The new, oil-tolerant...

To be more efficient, industry needs products that allow engineers to work smarter and that is precisely what drives the development of Henkel’s LOCTITE® anaerobic adhesives.  Although thread and flange sealing are long-established technologies, the company continues to introduce new benefits with successive generations of products and its latest formulations make no exception.

LOCTITE® 577 is a medium strength, general-purpose thread sealant for parallel/parallel and taper/parallel threads and fittings.  It is designed to lock and seal all metal pipes and fittings as well as other threaded assemblies, providing an instant, low pressure seal that will not creep, shrink or shred. Once fully cured LOCTITE® 577 will provide a high pressure seal, resisting the burst pressure of the pipe in most instances.

By comparison with traditional tapes or hemp and paste combinations, Henkel’s LOCTITE® 55, takes half the time to create a secure seal on threaded pipes.  And now, with the introduction of the new 160m dispenser, the method is even more cost effective.  A single reel will seal up to 405 joints with a half-inch thread size.  

Application is quick and easy and the product is suitable for locking and sealing both metal and plastic pipes and fittings.  Simply wind the sealing cord onto the first pitches clockwise and cross over the threads; the pack advises the correct number of turns for the application.  Cut the cord using the dispenser’s cutting device and press the loose end onto the thread.  Finally screw the fittings with a pipe wrench.

LOCTITE® 55 needs no cure time and results in an immediate, full pressure seal.  It also allows reliable re-adjustments and can be backed off by up to 45 degrees...
