Why you should be using torque sealant
Although torque sealants (screw locking paints) have been in production for over 60 years, their general function and the associated range of applications is only sparsely documented, if at all. There are various reasons for this.
Firstly, the screw locking market is considered to be small in relative terms compared to other industries and therefore has limited public interest. On the other hand, the term “screw locking paint” can be confusing because it only describes a part of its range of applications.
Nevertheless, screw locking paint is used across the board in a large number of industries. These include, among others, the automotive industry, the aviation and space travel industry, the rail and railway industry or, manufacturers and service providers of fairground rides. In the end, it’s hard to find manufacturing industries that don’t have points of contact with screw locking paint. Why? Because screws are used everywhere there. And where there are screws, you can usually also find screw locking paint.
Due to the large number of different industries in which screw locking paint is used, five different main fields of application have emerged over the years:
Visual loosening indicator
Screw locking paint is used as a visual loosening indicator to immediately detect loosening/loosening of safety-relevant screw connections.
A wind turbine secured with screw locking paint
Visual check mark
Screw locking is used as a visual check mark to indicate that a bolted joint has already been properly tightened or other work piece checked/approved.
A rail line secured with screw locking paint
Screw locking paint is used as a tamper indicator to indicate whether screw connections or components have been loosened without authorisation. This is often used in connection with warranty claims.
A laptop secured with screw locking paint
Screw locking paint is used as an assignment marker to indicate which point in the production chain (e.g. production, installation, maintenance) worked last on the given workpiece.
A control cabinet secured with screw locking paint
Screw lock lacquer is used as a screw lock to secure screw connections.
A roller coaster secured with screw locking paint
As a result of these different possible applications, different terms for the product “screw locking paint” have been established over the years. Common terms include: sealing lacquer, seal lacquer, screws sealing wax, sealing wax, security seal, locking varnish, security marker, marking paint, screw identification paint, identification varnish, torque seal, torque sealant.
