Fastener Coatings
Functional coatings are a great option to add additional locking, securing, holding, or sealing functions to fastening elements. Find out which one is right for you.
Functional coatings are system solutions for fastening elements that are exposed to mechanical stress, such as screws and nuts. They consist of different polymer composites, for example polyamide, plastisol, or polyolefin. Depending on the coating, they provide a locking, securing (captive), holding, or sealing function.
There is a suitable functional coating for every application, whether it is for securing against vibrations, for securing against fastener loss, for sealing in the thread, for sealing under the head and much more.
The securing functionality is integrated directly into the fastener
Functional coatings provide a strong and reliable securing function for fasteners
Functional coatings are a lower cost securing option, as no additional parts are needed
Added functionalities prevent fasteners from being lost
The coatings are captive parts of the connection, which cannot be lost or forgotten
For our jamming coatings, parts of the threads are given a coating of highly-elastic, abrasion-resistant polyamide. This fills in any axial play between the screw and the internal thread and thus creates a dense, vibration-resistant connection. We offer thread-locking and thread-sealing options:
Thread-Locking
Reliable and cost-effective systems for thread-locking fastened joints. Suitable for nearly all materials and temperature ranges from -56 °C to 200 °C (Nytemp® Patch). Reusable.
Thread-Locking & Thread-Sealing
Similar properties as the TufLok® and Nytemp® Patch but here the jamming coating is going all around the thread, creating a fluid and gas-tight seal.
Sealing coatings provide a protective barrier that prevents contaminants like dust, moisture or chemicals from entering the fastening joint. Thus, they enhance the longevity of fasteners by offering corrosion resistance and wear protection. Some options include:
Sealing
Plastic coating that eliminates the need for additional washers, seals, or O-rings. Excellent sealing properties against fluids and gases. Protects sensitive surfaces from damage.
Sealing
Similar to Nyseal® under-head coatings but can achieve greater coating thickness. Very good sealing properties. Long service life with no shrinkage or drying out.
Thread-Locking & Thread-Sealing
Coatings of highly-elastic, abrasion-resistant polyamide with both a thread-locking and sealing function. Resistant to alcohol, oil, fuel, and most thinners.
Adhesive coatings are the most secure preliminary coatings for threaded parts with higher safety requirements. These coatings consist of the smallest microcapsules. These microcapsules are destroyed in the installation process by pressure and shear loads – curing then starts immediately. Adhesive coatings are a reliable safeguard against loosening and are suitable for virtually all surfaces and materials. The options we offer include:
Precote® 30/80/85: A varnish-like pre-coating system based on microencapsulated acrylates for the locking and sealing of threaded parts. The adhesive function becomes effective only on assembly.
These functional coatings keep the fastening elements in their place during transport or assembly. They can thus help reduce assembly times for the end user and prevent installation errors. An example is Nystay®:
Nystay® is a plastic precoating (polyolefin-based) which helps to keep fasteners in place in their respective application or assembly group. It is non-toxic, environmentally friendly, and can be applied to a diverse range of fastening elements such as screws, shafts, rivets, studs, or pressed and turned parts.
