Anti-Corrosion Coatings |
If your business uses equipment or chemicals that are susceptible to corrosion, you should consider anti-corrosion coatings. These protective coatings are applied to corrosion vulnerable surfaces like pipes, piping, valves, etc. Most of the time these coatings are painted over with an epoxy or an acrylic resin. However, some manufacturers and dealers apply coatings with specially formulated coatings that resist corrosion through a special chemical reaction. It is important that you choose a suitable anti-corrosion coating for your work. It is important that the coating is not too thick as it may increase the surface tension of the metal and this could lead to corrosion.
The type of
anti-corrosion coatings you use depends on the nature of your application. For example, the barrier coatings provide a chemical barrier between the chemical and the corrosion-causing agent. Thus, the chances of corrosion and other harmful effects are significantly reduced. Other types of anti-corrosion coatings used are the sacrificial anodized, sacrificial nitriding and sacrificial martensitic. Depending on your specific application and coating thickness, you can choose the right one that suits your needs.
Corrosion resistant coatings includes a layer of protection on the metal, which prevents further corrosion of the metal when exposed to an acidic compound. The protective layer is usually applied on the metal using thin layers of paint, epoxy, etc., after preparing the substrate with a catalyst, before the application of the coatings. The other type of anti-corrosion coatings used is the barrier coating, which is used to prevent a chemical from penetrating the substrate. The barrier coatings includes barrier coatings with a barrier, electrostatic, electromagnetic and chemical barriers.
Anti-corrosion coatings can be used in a wide-range of products. The market is witnessing launch of new products in the recent past. For instance, in October 2021, Azelis announced a new distribution agreement with Hexigone, a UK-based manufacturer of smart corrosion inhibitors, for the distribution of Hexigone corrosion inhibitors across mainland Europe, Italy, Turkey, Ukraine, and the Baltics region.
