Application reasons
Our torque sealants can be used in a variety of ways. Learn more about the benefits of securing your product with one of our coatings.
1
Torque loosening indicator
To immediately recognise any loosening of safety-relevant screw connections.
2
Visual inspection marker
To indicate that a screw connection has already been properly tightened or another workpiece has been checked.
3
Tamper indicator
To indicate whether screw connections or components have been loosened without authorisation. This is often used in connection with warranty claims.
4
Assignment indicator
To indicate which point in the production chain was the last to work on the workpiece in question.
5
Threadlocker
To secure screw connections.
Torque sealant is a varnish that is applied to mechanical fasteners and usually acts as a "visual safety mark" or inspection seal. Torque sealant is available in different colors and in transparent. Most torque sealants currently available on the market are solvent-based but more environmentally friendly variants, for example water-based (VOC-free) torque sealants, have been gaining in importance in recent years as they are much gentler on humans and nature.
Due to the many different fields of application, there are many different terms that can be assigned to the umbrella term "torque sealant". These include: torque seal; torque seal paint; tamper proof sealant; tamper proof indicator paste; torque inspection seal; torque indicator paste; torque stripe; witness mark; marking ink; screw protection varnish.
