Corrosion & Metals: The Bully & The Victim

Corrosion & Metals: The Bully & The Victim

Science can be confusing. There’s an endless set of laws and theories involved, numbers to remember and chemical reactions to observe. Unfortunately, CORROSION is a scientific process. It plagues nearly all industries, destroys items of value and causes headaches, stress and financial losses.

CORROSION is the enemy!

If you’re not a scientist, but want a fuller understanding of this persistent enemy, then this article is for you!

I’m going to break down corrosion and various methods of corrosion protection with a traditional analogy:

A Bully, his Victim and an Interloper.

NOTE: By no means do we mean to make light of bullying or its devastating effects. We feel that this analogy provides a simplistic way to comprehend corrosion. If you or someone you know is being bullied, visit for more info on how to properly deal with the situation)

The Corresponding Roles

Corrosive Gases and Moisture

We’ve talked at length about the causes of corrosion. Put simply, the most common causes of corrosion are:

  • Corrosive Gases (Sulfuric Gases)
  • Moisture

You can picture these elements as the bully in this analogy, picking on his victim (ferrous and non-ferrous metals).

Ferrous and Non-Ferrous Metals

The metals that degrade by way of corrosion are the bully’s victims:

  • Ferrous Metals
  • Non-Ferrous Metals

Whether the influence is rapid and immediate or drawn out over time doesn’t matter. What’s important is that the bully’s effects on the victim are drastic.

The Interloper

The form of corrosion protection used to protect metals can be thought of as the interloper:

  • Galvanization
  • Conversion Coatings
  • Volatile Corrosion Protection
  • Intercept Technology

These are the third parties who stand in-between the bully and his victim in an attempt to stop the caustic process.


A common method of corrosion protection is galvanization. We’ve mentioned it before. Galvanization is a process in which a ferrous or non-ferrous metal is coated with zinc.

The zinc acts as a sacrificial anode by way of giving up its electrons and corroding in place of the metal it’s coated on. It takes the bully head-on.

In this sense, Galvanization stands up to the bully for a period of time. While at first it defends the bully’s victim (the ferrous/non-ferrous metal), eventually the bully’s influence is too much for the interloper to take.

Exposed Ferrous & Non-Ferrous MetalsAs the bully’s caustic behavior is directed towards galvanization, it wears him down. Over time the galvanization interloper surrenders, throwing in the towel and leaving the victim completely exposed to the bully’s onslaught.

Conversion Coatings
Conversion Coatings

Conversion coatings are chemical and electro-chemical process in which a metal’s surface is converted into a derivative that’s more suited for corrosion inhibition.

In this analogy, a conversion coating is an interloper who attempts to train the victim how to defend himself. He gives him defense tactics, informing him of what to do when faced with the bully.

Conversion coatings are ineffective though for a few reasons. First and foremost, conversion coatings DO NOT WORK ON NON-FERROUS METALS. That’s an entire class of metals that conversion coatings cannot defend.

Second, conversion coatings wear away quickly when faced with friction.

This means that over the Exposed Ferrous & Non-Ferrous Metalscourse of time, the conversion coating’s attempts at teaching the victim how to defend himself will be in vain. The persisting bully will overcome the victim’s new defense strategies and continue to affect him.

Volatile Corrosion Protection

VCP's and Metals

Volatile Corrosion Protection incorporates any compound-releasing storage materials that attempt to stop the corrosion and oxidation of ferrous & non-ferrous metals.

They emit a vapor when stored in packaging, coating the metal inside and forming a barrier. While VCP’s claim to protect metals from corrosion, in reality they compromise metals’ integrity.

In our analogy, the VCP interloper initially defends the victim, following him everywhere he goes. Anytime the bully strikes, the VCP interloper is there to defend him.

However, over the course of time, the interloper begins to “smother” our victim. His ongoing presence becomes just as much as a negative effect on the victim as the bully’s torments!

This is because VCP’s contain volatiles. The compounds released by VCP’s are oily, ineffective at preventing corrosion and their ingredients are mostly unknown. As a matter of fact, other countries have banned the use of VCP’s due to the volatile chemicals they contain.

The Result of VCP ProtectionIn effect, our VCP interloper eventually turns around and starts picking on the victim along with the bully himself!

The VCP and the bully spread their influence from our one defenseless victim to the ENTIRE PLAYGROUND of students, subjugating them to caustic and unhealthy behavior.

Intercept Technology

Intercept Technology, the protective material used in all of PreservAll’s preservation bags, surrounds metals with a blend of copper and plastic in order to protect them from corrosion.

Copper is naturally un-reactive, which means it doesn’t undergo drastic chemical or structural changes when in contact with other elements. By making alterations to its atomic structure, the copper used in Intercept Technology becomes more reactive. Increased reactivity means that all forms of corrosion – gases, moisture, etc. – are drawn towards the Intercept material.

Intercept Technology acts as a sacrificial anode by taking on corrosives. The essential difference between Intercept Technology and the other forms of corrosion protection listed in this article is that Intercept neutralizes corrosives.

In our analogy, Intercept packaging is an interloper that solves the victim’s bully problem. Standing in place of the victim, it takes on the bully’s caustic behavior, counteracting and neutralizing it.

The bully is gotten rid of for good, and the ferrous metals and Intercept live together in harmony!Intercept and Metals

Understanding Different Types of Gun Storage Bags

PreservAll sells corrosion inhibitor bags. One of our most popular product lines – gun storage bags – are just that, corrosion inhibitorsBut like any other industry, there are many products available.

However, there’s crucially important information for those shopping for corrosion inhibitor products: Some corrosion inhibitors use ineffective & dangerous materials.

They can compromise the integrity of your guns through residue and will most likely lead to rust.

Understanding Different Gun Storage Bags

This Article Requires a Preface

There are certain designations of corrosion inhibitors that we’ll be unable to name throughout this article…this is for legal purposes. 

The objective of this article is to increase consumer awareness of potentially dangerous chemicals and materials in certain corrosion inhibitorsBecause we cannot explicitly state other brands of corrosion inhibitors in this article, we will hereby refer to corrosion inhibitors as either:

Intercept Corrosion Inhibitors vs Other Corrosion Inhibitors

  • Not all products in the Other Corrosion Inhibitors category are dangerous, but a great many of them are.
  • While we cannot directly name the brands contained in the category itself, we will say that members of the Other Corrosion Inhibitors group have a presence in the packaging marketplace.
  • If you’ve browsed for anti corrosion products before then you’ve come across them.

How Corrosion Inhibitors Work

A corrosion inhibitor has one primary purpose – to stop the degradation of whatever they’re aimed to protect.

Corrosion inhibitors can be used to protect a wide range of things, including firearms, tools, engines, electronics, heavy machinery, etc.

Products like these contain metals that corrode over time when exposed to certain reactive gases in the atmosphere. This results in increased costs, reduced efficiencies and additional labor for those involved.

Different Methods of Corrosion InhibitorsCorrosion Inhibitors Work in One of Three Ways:

NeutralizingAbsorbing or Blocking Reactive Gases.

 ✅ Neutralizing Reactive Gases ✅

Intercept Corrosion Inhibitors neutralize gases by acting as a preferential site of corrosion. The Intercept material bonds with the corrosive gases attempting to enter the bag.

This means that the Intercept Corrosion Inhibitors themselves corrode. Essentially, they “take one for the team”, leaving the item it has been stored with protected and unharmed.

Rather than the protected item corroding, the Intercept Corrosion Inhibitor itself degrades over time.

This is the technology employed in PreservAll’s gun storage bags and it’s the most efficient on the market.

 ❌ Absorbing Reactive Gases ❌

Some Other Corrosion Inhibitors will absorb reactive gases present in the atmosphere but fail to completely neutralize them.

These types of products simply retain the reactive gases until reaching their maximum saturation point.

Fluctuations in temperature and humidity cause them to outgas – this is the process by which a solid releases a gas that had been previously absorbed or trapped.

Other Corrosion Inhibitors absorb reactive gases without neutralizing them. This means that they re-release these contaminants.

They inadvertently expose the objects they were intended to protect with the agents of corrosion they were intended to eliminate.

Needless to say, these types of corrosion inhibitors are counterproductive.

❌ Blocking Reactive Gases ❌

There’s some Other Corrosion Inhibitors, that don’t absorb reactive gases at all.

Instead, they contain oils that vaporize into a chemical cloud/barrier layer inside their containers.

This barrier is designed to coat the item it’s supposed to protect. This hypothetically keeps reactive gases from causing corrosion on the item.

Inserted into coatings, adhesives, plastics, powders and sprays, these chemicals leave deposits on the items they’re designed to protect and are often inefficient.

These corrosion inhibitors never truly neutralize the reactive gases in the first place.

Rather than protecting the materials they’re intended to, Other Corrosion Inhibitors that utilize barrier layers can harm precious metals and serve as a potential health hazard.

Chemical Used in Barrier Layers

Someone looking for an anti corrosion product may come across a multitude of Other Corrosion Inhibitors and think they sound effective.

But what’s in these anti corrosion materials?

Nobody really knows.

This is because Other Corrosion Inhibitors rarely list the chemicals in their formulas.

Many don’t display their active ingredients and materials by way of listing them as “trade secrets”. In doing this, they aren’t obligated to disclose what they’re comprised of.

Research done by independent laboratories has exposed the active ingredients found in some Other Corrosion Inhibitors:

  • Truethanolamine
  • Ammonia Hydroxide
  • Ethyl Acetate
  • Trimethyl
  • Trimethylbenzene
  • Propylene Glycol
  • Butyl Acetate
  • Phosphoric Acid

Make no mistake, this is only a small sampling, and many other chemicals have been found as well.

Many of the chemicals found in Other Corrosion Inhibitors are on the EPA Registered Pesticide List, OSHA’s Air Contaminants List, and are found to be carcinogenic. Some are even flagged by the Chemical Weapons Convention.

Intercept Technology & PreservAll

Compare the previous list of ingredients with that of the Intercept Corrosion Inhibitors used in PreservAll’s gun storage bags.

  • Copper
  • Polyethylene

As you can see, there’s quite a difference. Intercept Corrosion Inhibitors are patented and since we don’t claim “trade secrets”, we have nothing to hide.

Our products contain a high surface area copper embedded into a polymer and nothing else. No volatiles, no carcinogens, no abrasives!

Intercept Corrosion Inhibitors have won environment awards, whereas many Other Corrosion Inhibitors have restrictions placed on them in other countries regarding health and environmental concerns.

These are important things to consider if you’re in the corrosion inhibitor market. Regardless of whether or not you purchase PreservAll bags or any other Intercept Corrosion Inhibitor products, we felt this was vital information that should be shared.
