Out of stock

⚙ Ideal For

  • Automotive electrical repair and diagnostics
  • Industrial relay and switch maintenance
  • Marine and maritime electrical systems
  • Circuit board and connector restoration
  • Intermittent electrical fault troubleshooting

✔ Benefits

  • Dissolves metallic oxide films that standard degreasers cannot remove
  • Restores full conductivity to corroded contacts in minutes
  • Zero damage to plastics, insulators, and circuit board components
  • Precision 200ml aerosol for drop-by-drop application
  • High dielectric strength — safe for non-conductive environments

Intermittent electrical failures, crackling audio, and signal drops are caused by non-conductive metallic oxide films that build up on bare metal contacts within weeks in humid or salty environments. Standard electrical degreasers remove surface dirt but leave oxide untouched, leaving intermittent failures unresolved.

CRC Kontakt 60 addresses this with a precision solvent that actively dissolves the oxide barrier, restoring full conductivity while remaining safe on all surrounding plastics, insulators, and circuit board elements.

Key Features

  • Dissolves Metallic Oxide Films — Specifically targets low-conductivity oxide layers on copper, silver, and base metal contacts that cause signal loss and circuit failures. Unlike general degreasers that only remove surface dirt, Kontakt 60 chemically dissolves the non-conductive oxide barrier, restoring full conductivity to corroded connections.
  • Zero Damage to Electronics — Safe on thermoplastics, thermoset resins, carbon tracks, and electrical insulators — the solvent won't cause stress-cracking, softening, or degradation of surrounding components. Critical in modern equipment where delicate trace circuits and polymeric housings are tightly packed alongside contact points.
  • High Dielectric Strength & Non-Conductive — Non-conductive formulation prevents leakage currents between circuit traces or components, making it safe for use on energized equipment after de-energisation and adequate drying time. Maintains electrical isolation while dissolving oxide.
  • Deep Penetration Into Sealed Assemblies — Seeps into sealed relay pins, multi-pin connectors, and corroded joints without requiring disassembly. The precision 200ml aerosol allows controlled drop-by-drop application directly to individual contact pairs, making it economical and waste-free on expensive equipment.

Description

Why Oxide Causes Persistent Electrical Failures

Intermittent crackling, signal drops, and complete circuit failures are caused by non-conductive metallic oxide corrosion on bare metal contacts. This film develops within weeks in humid, salty, or corrosive environments and introduces electrical resistance that degrades performance or causes complete signal loss. Standard degreasers remove dirt but leave oxide untouched, leaving the root cause of intermittent failures unaddressed. Only an oxide-dissolving formula like Kontakt 60 can restore full conductivity.

Working Safely in Modern Electronic Assemblies

Contemporary printed circuit boards, automotive relays, and marine switchgear pack delicate copper traces and polymeric housings into cramped layouts where aggressive industrial degreasers could cause permanent damage. Kontakt 60 penetrates corroded joints without damaging adjacent plastics, resin elements, or carbon traces — a critical safety distinction that makes precision restoration possible without component replacement.

Professional Restoration Workflow

For best results, follow this three-step process: (1) apply Kontakt 60 to dissolve oxide from corroded contacts, (2) flush with a fast-drying solvent like Kontakt WL to remove dissolved oxide particles, and (3) apply protective contact film like Kontakt 61 to seal bare metal against rapid re-oxidation. This workflow restores full conductivity and prevents rapid repeat failure.

Application Instructions

  1. De-energise the circuit completely — Never apply cleaner to live electrical systems. Switch off power at the breaker or source and allow adequate time for capacitive discharge on power supply circuits.
  2. Allow components to cool — Allow equipment to reach ambient temperature before application. Hot components may cause premature solvent evaporation or safety hazards.
  3. Prepare the aerosol — Shake the 200 mL aerosol briefly to ensure uniform product consistency before dispensing.
  4. Apply controlled droplets — Direct the spray nozzle to apply small, controlled droplets directly onto contact pairs, relay pins, or socket pins. Do not soak or flood the area; precision application prevents excess product accumulation.
  5. Work the contacts mechanically — For accessible contacts, switch back and forth, rotate potentiometers, or gently wipe pins with a lint-free cloth to physically break down oxide and distribute the dissolving solvent throughout the contact surface.
  6. Allow dwell time for sealed contacts — For sealed relay pins or multi-pin connectors, allow 10–15 minutes without mechanical agitation to allow the solvent to penetrate and dissolve oxide fully.
  7. Flush with fast-drying solvent — Remove dissolved oxide residue by flushing the contact area with a fast-drying solvent such as Kontakt WL. This prevents redeposition of dissolved particles on contact surfaces.
  8. Apply protective contact film — Once dry, apply a protective contact film such as Kontakt 61 or Kontakt 40 to create a barrier against rapid re-oxidation of bare metal.
  9. Allow drying time — Allow 5–10 minutes of drying time before re-energising electrical equipment. Ensure all solvent has evaporated.
  10. Test the circuit — Before returning equipment to service, test the circuit to confirm intermittent electrical issues are fully resolved and conductivity is restored.

FAQs

Can I use CRC Kontakt 60 on live electrical equipment or do I need to switch it off first?

Always de-energise the circuit completely before applying the cleaner. Switch off power at the breaker or source and allow adequate time for capacitive discharge on power supplies. Never apply to energised electrical systems.

What's the difference between Kontakt 60 and standard electrical degreasers?

Standard degreasers remove dirt and grease but leave non-conductive metallic oxide films intact, leaving intermittent failures unresolved. Kontakt 60 chemically dissolves the oxide barrier itself, restoring full conductivity. This makes it essential for troubleshooting true oxide-related electrical failures rather than just cleaning.

Will this product damage plastic components, insulators, or circuit board traces?

No, it's safe on thermoplastics, thermoset resins, carbon tracks, and electrical insulators. The precision formula dissolves oxide without stress-cracking or softening surrounding components — a key advantage over aggressive industrial degreasers on modern tightly-packed electronics.

What's the best way to apply this product without wasting it on expensive equipment?

The 200ml aerosol allows precise drop-by-drop application directly to individual contact pairs, relays, or pins. This controlled dispensing minimizes product waste while ensuring oxide-dissolving solvent reaches exactly where needed. Work mechanically (switch contacts back and forth) to distribute the solvent and speed up oxide dissolution.
