Anti Corrosion Protection: Epoxy Powder Coatings
The most significant single cause of plant and equipment breakdown in industrial procduction facilities is corrosion. It affects almost everything: machinery, vessels, structures, supports, and pipelines. The main culprit is atmospheric corrosion in the air (oxygen) and water (moisture, humidity, vapor, etc.). However, environmental factors, including high temperatures and pressures and harsh substances, chemicals, and gasses, can also accelerate the corrosion of carbon steel and other metals.
Corrosion is common in marine environments exposed to salt spray or compounds that cause corrosion. Common gaseous industrial air pollutants, such as sulfur dioxide, ozone, and nitrogen dioxide, can also induce corrosion. Industrial chemicals such as chlorides, acetic acid, and formaldehyde can also be corrosive.
Corrosion is something one must bear in mind when considering new packaging automation, especially if:
-the packaging machine will be exposed to temperature cycling
-the packaging machine has to endure a caustic wash down procedure
-the packaging machine will handle corrosive substances like salt and other chemicals
In cases like this, make sure you and your machine manufacturer are on the same page. The manufacturer will suggest suitable materials, design, and appropriate anti-corrosion coating, like an epoxy powder coating for Stainless Steel.
Why Epoxy Powder Coating
Powder coatings and Stainless Steel are becoming increasingly popular, mostly for corrosion resistance and endurance. An epoxy powder coating can protect against repeated mechanical stresses, weather, and other environmental challenges often faced by the end-use application. These coatings are used across a range of industries: from a child’s first bicycle in pink to a massive pipeline channeling oil across vast distances. At Nortech Packaging, we are approaching the matter of corrosion seriously, making sure to provide the proper protective coating that can prevent the formation of chips, cracks, rust, and blisters, leading to failure of the material being coated.
Essential Features of Epoxy Coating
Epoxy is created by polymerizing or combining a resin and a hardener with a specified catalyst. The result is a curing process in which epoxy is produced with high mechanical properties and great temperature and chemical resistance. The chemistry of epoxies and variations in the curing process enables them to be created with a vast range of properties. In addition, these properties can be modified for greater thermal insulation or thermal conductivity combined with high electrical resistance depending on the application. We can help you choose a coating for your application that fits best within your project budget.
Epoxy Powder Coating Benefits
There are numerous benefits to using an industrial epoxy powder coating.
- Powder coatings made from epoxy are a tough, lasting, and durable coating for metals.
- Their excellent hardness and resistance to impact and abrasions improve the performance of products over liquid coatings.
- They help maintain essential equipment performance so production can run efficiently, ultimately improving the bottom line.
- The production process of powder coatings ensures that their appearance and color are consistent, which is important when aesthetics and decoration play a significant role in the application.
- An epoxy powder coating has insulation properties that make it effective as a high dielectric insulator on copper or aluminum conductors. For cable installations, it negates concerns of cut-through or high-voltage spikes providing insulation that reduces the need for costly and time-consuming lamination processes.
A case study
Our recent project, the ROO-100 Pouch Fill & Seal Machine for desiccant powder, is an excellent example of a machine that features an anti-corrosion coating. Some desiccant and anti-moisture products contain substances that can be corrosive to the equipment, like calcium chloride and other types of salt. This is why we used epoxy coating for this project. This ROO-100 model features white epoxy resin powder coating on all machine surfaces not under a wear factor.
