Voltage Cable Co. Secures Patent for ISO-COAT®: A Breakthrough in Hermetically Sealed Audio Circuit and Cable Technology

06 Aug, 2025

Sydney, Australia – June 26, 2025

Voltage Cable Co. has been officially granted Australian Patent No. 2024204464 for its ISO-COAT® technology,  a landmark development in corrosion-resistant cabling for the audio industry. This invention establishes a new category of structurally reinforced, hermetically sealed terminations designed to protect against the primary causes of cable failure: oxidation, corrosion, and mechanical fatigue.

 

A New Category in Corrosion-Resistant Cabling

Co-invented by Peter Frederick Reynolds and Thomas John Welladsen, ISO-COAT® introduces an impermeable membrane that forms an airtight barrier over solder terminations and audio assemblies. The result is a first-of-its-kind protective system for guitar cables, audio connectors, and electronic circuits of any kind. Built to endure the rigors of professional use, the ISO-COAT® process delivers a chemically bonded hermetic seal that blocks air, moisture, and atmospheric attack from compromising signal and structural integrity

 

Structurally Reinforced Hermetic Impermeable Membrane

Unlike traditional heat-shrink tubing or silicone coatings, which remain porous at a microscopic level, ISO-COAT® forms a complete hermetic seal. This structurally reinforced membrane not only halts the chemical reactions responsible for corrosion and oxidation. It also delivers measurable mechanical support to the vulnerable soldered connection points – the most common failure zones in standard instrument and guitar cables.

 

Beyond Coiled Cables - A Patent with Broad Applications

The significance of this advancement extends beyond coiled guitar cables. The patent protects the use of the ISO-COAT® method across any audio circuitry where soldered joints are present. By encasing these joints in a cured, non-porous barrier, Voltage Cable Co. has introduced a solution that addresses electrical degradation at its root cause. The result is a long-lasting, high-performance audio component that maintains electrical characteristics and tonal clarity over time.

 

Durability is Now a Matter of Record. It's the New Standard. 

Durability is no longer a marketing claim. It is now a matter of record. The hermetic seal produced by ISO-COAT® transforms vulnerable terminations into chemically stable, structurally sound units capable of withstanding decades of use. This technology sets a new benchmark for what defines a durable guitar cable and a truly durable instrument cable.

 

Multi-Stage Development and Field-Proven Performance

The development of ISO-COAT® was the result of multi-year research and rigorous field testing. Each cable undergoes a multi-stage curing process that ensures proper adhesion and mechanical strength. Once applied, the membrane acts as a permanent defense system for the electrical and mechanical connection – withstanding temperature changes, humidity, shock, vibration and atmospheric attack.

 

Scalable Technology for Audio and Beyond

This patent is not limited to coiled cables or even instrument cables alone. It applies broadly to all audio circuits that require protection at the termination level. In that sense, ISO-COAT® represents a scalable, category-defining innovation across multiple sectors, including audio manufacturing, critial-grade audio electronics, and high-reliability consumer products.

 

An Industry First – Redefining Cable Failure Prevention

The patent grant formalizes Voltage Cable Co.'s position as the first manufacturer in the world to introduce hermetically sealed guitar cable terminations to market. It also signals a serious technical shift in how the music and electronics industries must approach cable durability and signal preservation.

Where traditional cables begin to fail after months or years of exposure, ISO-COAT® products maintain full performance with no degradation in resistance, capacitance, or signal-to-noise ratio. Artists, engineers, and technicians can expect consistent results across thousands of connection cycles, all backed by a transferable lifetime warranty.

 

Protected Technology with Global Implications

ISO-COAT® is now protected under Australian Standard Patent No. 2024204464, with international patent protection pending under PCT/AU2024/050220. This positions Voltage Cable Co. to lead not only the boutique instrument cable category, but the global standard for corrosion-resistant connection technology.

 

More Than a Patent - A Structural Breakthrough

This announcement is not simply about intellectual property. It reflects a major technical achievement. ISO-COAT® stands as the definitive answer to termination failure in audio systems. And with this patent milestone now secured, Voltage Cable Co. will continue advancing audio cable design with the same relentless focus on longevity, reliability, and structural integrity.
