The Business Built on Preventing Rust

Cortec Corporation has spent 49 years charging customers to prevent a corrosion failure that almost never appears, building a privately held company that now runs nine plants and ships into more than 100 countries.

Most executives treat prevention as a cost center to minimize rather than a compounding asset.

They fund the visible fix, the dramatic rescue, the emergency retrofit, while starving the unglamorous work of preventing it in the first place, because nothing happening produces no photograph and no bonus.

Building legacy through invisible prevention requires a different kind of patience: deliberately selling an outcome nobody can observe, to buyers who cannot be blamed for staying and can only be blamed for changing.

Cortec Corporation discovered this in a Minnesota garage in 1977, and spent five decades turning it into a 100-country monopoly that nobody can see working.

Case Study: How Cortec Built a Global Business Through Invisible Prevention

In October 1977, Croatian immigrant engineer Boris Miksic shipped his first 1,200 vapor-phase corrosion inhibitor emitters from a rented farm garage in Hugo, Minnesota.

Miksic arrived in America three years earlier after being blacklisted from engineering work for joining anti-Communist rallies.

He had no distribution network or established brand. What he had was a difficult product to demonstrate: a vapor that protected hidden metal against damage that might not appear for years.

A milestone came in 1981, when Cortec patented its Corrosion Inhibiting Articles.

The technology releases an inhibitor that travels through an enclosed space and forms a protective molecular layer on metal surfaces. It can protect areas that are difficult to reach with conventional coatings, including machinery interiors and equipment in storage.

Cortec was selling protection where inspection and maintenance were hardest.

Rather than compete solely on price with established coatings suppliers, the company pursued demanding applications where corrosion carried serious consequences.

A Cortec aircraft brochure describes testing at NASA’s Kennedy Space Center marine atmospheric exposure site. According to the brochure, Cortec formulations showed the least crevice and galvanic corrosion among the products evaluated.

That evidence helped address the central obstacle in selling prevention: customers needed confidence in an outcome they might never see.

Credibility accumulated through testing, field experience, and equipment that remained protected. Each successful application gave the next procurement team another reason to trust the product.

The resulting advantage extended beyond chemistry.

A buyer who approves a corrosion inhibitor and sees no damage for a decade may struggle to demonstrate how much loss the decision prevented. A buyer who switches suppliers before corrosion appears faces a much more visible question: why change?

That asymmetry can make established suppliers difficult to displace. Switching requires a customer to accept uncertainty around a failure that may take years to emerge.

The sale is hard to win because the benefit is invisible. Once earned, that trust can be difficult for a competitor to replace.

Cortec’s growth reflects the scale it built around that proposition.

Twin Cities Business reported sales of $28 million in 2009 and $34 million in 2010, with $42 million projected for 2011. Headcount rose from 168 to 215 over the same period.

By its 40th anniversary in 2017, Cortec operated nine plants and distributed products in more than 100 countries. Its portfolio exceeded 400 products, supported by more than 60 patents.

Those figures establish a substantial international business, rather than a literal monopoly.

Private ownership also gave Cortec continuity as it developed products and customer relationships. Building confidence in long-term protection requires sustained investment, particularly when performance becomes clear only after years of use.

Patient ownership created room for that work. Testing and execution still had to justify the customer’s trust.

The broader opportunity remains enormous.

The NACE IMPACT study estimated the annual global cost of corrosion at $2.5 trillion, equivalent to roughly 3.4% of global GDP. It estimated that existing corrosion-management practices could save 15%–35% of that cost.

Those are study estimates, rather than a current annual tally, but they illustrate the economic value of prevention.

For business owners, Cortec offers a useful lesson: an overlooked problem can support a durable company when failure is expensive, protection is difficult to verify, and customers need strong evidence before changing suppliers.

The lasting advantage comes from making an invisible benefit credible enough that customers keep choosing it.

From Visible Rescue to Invisible Prevention

1. Price the Switching Risk, Not Just the Service

Replacing a trusted vendor requires more than finding a better offer. Procurement teams also weigh the disruption, uncertainty, and responsibility that come with changing suppliers.

Long-standing audit relationships, including those at Lloyds Banking Group, illustrate how deeply an incumbent can become embedded in an organization. A challenger must make switching defensible, as well as make the service attractive.

For an established provider, the opportunity is to reduce uncertainty through consistent performance. For a challenger, it is to give the buyer credible evidence and a clear transition plan.

2. Transfer the Liability, Not Just the Treatment

The promise to fix a failure can be worth more than the treatment intended to prevent it.

Termite protection makes that distinction tangible. Providers such as Orkin sell ongoing protection backed by guarantees, though the coverage and conditions vary by agreement.

A retreatment commitment and a repair commitment address different risks. One pays for another attempt at controlling the problem; the other may help cover the damage left behind.

When designing a prevention service, make clear what happens if it fails. The scope of that responsibility can be central to the customer’s decision.

3. Become the Backstop No One Notices

Most policyholders never interact with the companies that help their insurers absorb major losses.

Founded in Zurich in 1863, Swiss Re operates in that less visible layer, providing reinsurance that helps insurers manage risks beyond what they want to retain themselves.

Its position illustrates an enduring business opportunity: supporting the organizations customers already rely on.

An essential business does not have to be the most visible business in the system. It does need the financial strength and operating discipline to deliver when the backstop is tested.

4. Count the Disaster That Never Gets a Headline

A fire that never starts produces no dramatic recovery story. Its value appears in uninterrupted operations, preserved equipment, and people who return home safely.

That makes prevention difficult to defend unless someone measures it. Property insurer FM combines insurance with engineering intended to help businesses identify and reduce potential losses.

The useful measures include hazards corrected, exposure reduced, and the estimated consequences of an interruption.

An uneventful decade can represent a substantial return on prevention. Making that return visible gives management a stronger basis for protecting the next decade’s budget.

From strategy to legacy

The hardest commercial position to win is selling the prevention of a failure nobody can observe, and once won, it may be the most permanent position a company can hold.

There is a particular discipline required to build value nobody can see working. The instinct to intervene visibly, to be caught saving something, is not strategy but theater.

Organizations mastering invisible prevention discover that the deepest loyalty comes from customers who cannot prove they were ever saved.

What does success look like, measured in headlines never generated?
