A passivator, also known as an anodic inhibitor, is a type of corrosion inhibitor that reduces or blocks reactions at the anode, thus shifting the potential of the metal to a more…
Which gets a surface cleaner, wet blasting or dry blasting?
Wet (vapor) blasting technologies and dry blastingare similar in performance with regards to surface preparation. The shortfalls of older wet blasting technologies have, unfortunately, often been carried over and associated with newer…
Are there some anti-corrosion applications in which airless spraying is a bad idea?
Airless sprayers work by pumping high-pressure paints or coatings through a hose to the nozzle of the spray gun. As the paint is forced through the tip of the nozzle, it gets…
How can I determine what blast pressure is best for my application?
The blast pressure directly determines the velocity of the blast media through the blasting nozzle, and therefore the impact force on the substrate. While there are a wide range of pressures that…
What is a plural component protective coating and what is it used for?
Plural component protective coatings, as the name suggests, are coatings that are made up of separate elements that are combined prior to application. High solid materials such as polyurethane, polyurea, and epoxy…
What do I need to consider when it comes to applying high solids coatings?
High solids coatings can offer numerous advantages when compared to solvent-based coatings. Some of these advantages include better durability, faster drying times and little to no emission of volatile organic compounds (VOCs)….
What kind of tool can measure a polarization curve in coulombs per second?
The tool used to measure a polarization current (1 amp = 1 coulomb per second) is called a potentiostat. A potentiostat is an essential device used in corrosion studies to investigate electrochemical…
Why should cathodic protection and a coating be used together to protect against corrosion?
No coating is flawless, so cathodic protection is an effective complementary method to protect structures in a corrosive environment. Applying a protective coating to metallic surfaces is the most effective method to…
Will using wet abrasive blasting instead of dry eliminate dust?
Firstly, before we answer this question it is important to clear up a common misconception. There is no such thing as a 100% dustless surface preparation method. (For background information on the…
Should I use a polyurethane or epoxy coating on concrete?
There is no shortage of options when it comes to concrete floor coatings, which are generally used to protect concrete floors from excessive wear and damage. Two of the most popular types…
