Contact Track Repair Coating AG TermoPasty 07976 — graphite touch-up lacquer for electrical contact paths

AG TermoPasty 07976 contact track repair lacquer is a graphite-based touch-up coating formulated to restore electrical continuity on worn or damaged conductive paths. Designed for precision maintenance, this conductive lacquer creates a thin, even graphite layer that reduces contact resistance and improves signal transfer on switches, potentiometers and connectors. The product is intended for targeted repairs where original contact surfaces have degraded due to wear, oxidation or mechanical damage.

Advantages

The graphite formulation provides reliable electrical conductivity while forming a thin, durable film that adheres to common contact substrates. The lacquer dries to a uniform finish suitable for sliding contacts and rotary elements, helping to re-establish low-resistance paths without significant change to mechanical tolerances. It is applicable in small, controlled amounts for localized repairs and can extend the service life of precision components by restoring functional surfaces.

Suitable for

• Repairing worn or intermittent switch contacts
• Restoring potentiometer tracks and rotary encoder contacts
• Touch-up on connector contact surfaces
• Maintenance of audio, instrumentation and control electronics

Key specifications

• Conductive medium: graphite-based formulation
• Coating type: thin conductive lacquer suitable for contact surfaces
• Finish: dry, matte graphite film compatible with sliding and rotary contacts
• Application scale: designed for precision, localized touch-up work
• Compatibility: suitable for metal and plated contact materials commonly used in switches and connectors

How to use

Prepare the contact area by cleaning away dust, grease and oxidation using an appropriate contact cleaner and allow the surface to dry completely. Apply the graphite touch-up lacquer sparingly to the damaged or worn conductive path using the applicator or a fine brush for accurate coverage. Allow the lacquer to level and dry according to ambient conditions; drying creates a thin conductive layer that should be tested for continuity and resistance. If necessary, apply a second thin coat after the first coat has fully dried to achieve the desired conductivity and surface coverage.

Usage recommendations

Use in a well-ventilated area and avoid excessive application that could alter mechanical fit of moving contacts. Perform a continuity and resistance check after cure before returning the equipment to service. Store the product capped in a cool, dry place away from direct heat sources and out of reach of children.
