Corrosion is one of the most underestimated and often misunderstood forces humans deal with on a daily basis. A large part of that underestimation is the image in many people's minds of what corrosion is. We tend to think and talk about corrosion similar to erosion: it's a geological time-scale force with which humans not only needn't engage but indeed shouldn't even concern ourselves, as it would be a futile waste of time and energy. Such a submissive attitude toward the natural forces may serve as a satisfactory spiritual practice, but to the discerning member of any competitive economic system, it is simply untenable. While the idea of battling corrosion may then conjure an image of poor Sisyphus and his infinite boulder displacement task, corrosion control can be done effectively and without anguish, as we've seen in our series of posts on the subject. Of course images and possibilities are interesting, but only hard data will tell the real story.Read More

This is fourth in a series on corrosion control; find the previous posts here.
Within the world of corrosion control, coatings can include a number of different materials and processes, from paints to plating, to enamel and even bio films. Functionally, however, corrosion control coatings are not so different; they mainly serve one or both of two purposes: physical barrier and sacrificial anode. In order to function as a physical barrier, a material must simply prevent the chemicals which cause corrosion, i.e. water, and oxidizers like oxygen, chlorides or sulfur compounds, from touching the metal being protected. We'll see in a moment how difficult this can be.Read More

It seems to be a daily occurrence where there is news of a breach of some sort, into private lives, or a company's "secure" information, and most assuredly the classified information of our governments. It has been well reported that these are systematic attacks. As the world has become more intricately connected, with increasing individual anonymity, and more "treasures" available, opportunities for thieves to prosper abound.Read More
Under seven feet of stone, in the foundation of Phoebe Hearst Memorial Hall, lies a small pool-sized room filled with all of humanity's knowledge prior to 1940. The room is sealed shut with a welded stainless steel door which is not to be opened until 8113 A.D. This room is the Crypt of Civilization.Read More

Impressed current cathodic protection (ICCP) uses the principle of cathodic protection to protect large metal objects in corrosive situations like ships or underground tanks. As a quick reminder from the second article in this series, cathodic protection uses the galvanic reaction as a benefit to protect smaller metals items. ICCP is used when the items needing protection are especially large or when fine-tuned control of the galvanic reaction is needed, as can be the case with ships which enter waters of varying salinity.Read More

This piece is second in a series of posts on corrosion control. The first post provided an introduction to corrosion control and gave an overview of some of the methods used. Here, we are going to dive deeper into the world of cathodic protection, one of the more practiced and effective ways of controlling corrosion in process. In a later post, we'll see how the principle of cathodic protection can be used in complex impressed current cathodic protection (ICCP) systems for delicate control over corrosion. First, we need some background to understand how it all works.Read More
"Corrosion Control" generally refers to the implementation of measures to reduce or eliminate corrosion in:
Corrosion control consists of different monitoring and control techniques used by industries to solve corrosion problems according to their requirements. Such methods are important to avoiding the expense and negative consequences of corrosion.Read More
Aren’t all anti-corrosion packaging materials the same?
No. Barrier protection products work in vastly different ways. The Intercept Technology line of products protects in two ways. First, they act as a moisture barrier. Second, Intercept reacts with and permanently neutralizes corrosive gases to form a corrosive gas barrier. This dual form of protection eliminates the two elements needed to form atmospheric corrosion. Intercept’s mechanism for protection is sacrificial, therefore, it won’t contaminate the product it’s protecting. The typical “waterproof” or vapor barrier bag/shroud concept is to attempt to keep the atmosphere and/or relative humidity from the protected product; whereas the emitting protection products, packaging and canisters, will surround the product with a volatile vapor.

Are desiccants needed with Intercept products?
Yes and no. If there are no large voids in the package, then the Intercept will react with the corrosive gases within the package and eliminate the potential danger without desiccating. However, if there are large voids that don’t allow the Intercept material to be close to some areas, then it would be best to utilize desiccants, making sure that the desiccants are not directly touching metals. Please consult with us for your recommended usage.

In professional basketball there is an adage that two great players are good to have on a team but a “big three” is needed to win championships. That notion has been supported in the past and with current day teams.
To continue the analogy, I think of the “Big Three” in manufacturing as being mechanical, electronics, and optics, all functioning efficiently together for the final product to work as designed. Point of purchase equipment, bank machines, scanning equipment, inspection equipment, and robotics are all tools and equipment containing the “Big Three”.

In 1986 Californians voted into law Proposition 65, also known as The Safe Drinking Water and Toxic Enforcement Act of 1986, the purpose of which was to protect the people of California from exposure, via drinking water and consumer products, to toxic substances which have been linked to cancer or birth defects. The act gives authority to California's Office of Environmental Health Hazard Assessment to maintain a list of chemicals shown by the FDA or similar national organizations to be carcinogenic or cause birth defects. Any company found to be dumping any of these substances into drinking water sources can be fined and required to discontinue the dumping. The act also states that any company which exposes consumers to significant amounts of these chemicals via their products must provide a warning on the product or in the store. Failure to comply with the necessary warning means the company can be sued by state or city government attorneys or private attorneys given proper notice to the company and the Attorney General.
