The CounterAct electrostatic corrosion control systems are a family of devices so unique and novel that patents were granted not only on the devices themselves but on the actual process the devices employ. The unique CounterAct process of corrosion protection, "electrostatic corrosion control by capacitive coupling" is the only tested and proven purely electronic corrosion control process for minimizing corrosion in open air structures and vehicles.

The first of the CounterAct  electronic corrosion protection patents issued in the U.S. followed several years later by a similar patent in Canada. Others now are pending worldwide. We invented, pioneered and perfected the CounterAct "electrostatic corrosion control process utilizing capacitive coupling" and still hold all the patents on these devices and electronic corrosion protection processes. The truly unique quality of CounterAct corrosion protection is demonstrated by the nature of the original CounterAct patents which not only covers our electrostatic corrosion control devices but the actual  capacitive coupling process governing these devices as well.



Our electrostatic corrosion control devices consist of three primary components:


1. A small pulsed DC power supply and control module (in the case of a typical passenger vehicle system about the size of a pack of cigarettes) is the heart of our corrosion proofing systems. The power supply is all solid state circuitry embedded in electronics grade (UL 94V-0 flame retardant) epoxy encapsulant  for long life and durability in any climate. On automobile and light trucks it is typically installed under the hood or in the trunk (wherever the battery is located ) where it runs off the 12V from the vehicle battery drawing less current than a typical digital clock.

2. A removable modular wiring harness with fused power lead to permit easy access to the power supply/control module for inspection or for easy transferability of our corrosion control devices to another vehicle.


CounterAct's capacitive coupling method uses a coupler with peel and stick aircraft grade adhesive that attaches right over the vehicle's paint.

3. One or more of our unique "programmed capacitive couplers". These capacitive couplers, which are attached to the protected metal surface with aircraft grade adhesive, are charged by the power supply/control module and function as if they were the positive half of a capacitor. They are wired to the power supply in parallel (each on individual circuits) and meticulously engineered so that each serves to produce a measured and specific limited range of capacitance and thus deliver a measured and specific limited range electrostatic charge via capacitive coupling. These  capacitive couplers are vital to the effectiveness of the system and we exercise the utmost care in their manufacture.


Together these three components serve to induce a negative electrostatic surface charge on the metal surface being protected (your vehicle's body for instance) thus capacitive coupling treats the metal body as if it were the negative half of a capacitor. This negative surface charge serves to interfere with the normal electrochemical corrosion processes that create corrosion on metals. (Please see "What is corrosion? " for a more thorough discussion and "CounterAct's Testing" for laboratory and Our Testimonials for Field documentation. )


At CounterAct CPR we specialize in the development and application of our own patented and proprietary electrostatic corrosion control technology. CounterAct utilizes capacitive coupling technology  in our "off the shelf" products for vehicles (seen on our Products page) and static structures as well as in specialized custom applications through our consulting division. If your intended corrosion proofing application is buried or submerged and lends itself to the more traditional electronic corrosion proofing methods such as cathodic or anodic protection we will gladly refer you to a reputable corrosion engineering consulting firm that specializes in these older methods. From time to time we are however, called upon  to devise "hybrid corrosion proofing systems" that employ our technology to protect open air structures combined with traditional electronic corrosion proofing methods to protect the portion of such an object which is buried or submerged. Although our exclusive proprietary technology makes up most of our projects, CounterAct does utilize more traditional methods of electronic corrosion proofing when a job requires it and should our client specify that CounterAct perform all corrosion control design and installation work directly rather than employ sub-contractors.
