Application Spotlight: Chemical Resistance

Pulp & paper, printing machinery and petrochemical are some of the industries that require highly dependable coating solutions to protect complex set of equipments against chemical reactions and reagents. Without adequate protection, the corrosive properties of certain chemicals, allow the chemical to damage the delicate surface of the expensive components.

A Quick Look at the Typical Environments that Require Chemical Resistant Coatings

Modern business processes often require the use of various acids and chemicals to achieve delivery objectives. That’s why chemical resistant coatings are required to provide long lasting protection to capital assets as well as maintain return on capital investment and productivity. Here is a quick look at the types of environments such coatings are used in:

  • Leach platforms
  • Agitators
  • Acid tanks
  • Holding tanks
  • Splash zones
  • Blast chillers
  • Drainage Gullies
  • Reactors
  • CIP storage tanks
  • Plinths
  • Waste water treatment plants
  • Chemical bunds
  • … and more!

Coatings with chemical resistance properties are truly ‘life-savers’ as they provide much needed resistance to ongoing chemical attack, exposure to harmful acids, oils and solvents, and even regular cleaning regimes that could cause erosion.

At A&A Coatings, you can be sure that we are the right partners to work with in terms of preventing potential major catastrophes from ever occurring. Our industrial coatings can be tailored specifically to your needs, enabling peace of mind in the process.

Individual Parts that can Benefit from Chemical Resistant Coatings

Now that you are much more familiar with the environments that require coatings with chemical resistance, let’s find out which individual parts benefit from similar coatings as well. It could be anything from:

  • Steam valves
  • Pipelines
  • Wind turbines
  • Valve bodies
  • Exhaust pipes
  • Generator mufflers
  • Pump housings
  • Bolts & fasteners

When it comes to applying coatings on parts like those mentioned above, you can count on our years of expertise in the application of chemical resistant coatings. We guarantee stellar adhesion to steel and concrete surfaces, and more.

How does A&A Coatings Apply Chemical Resistant Coatings?

For starters, chemical resistant coatings can be achieved through three different coating processes. Depending on your needs, we will first determine if spray & fuse hardfacing, plasma spraying or metalizing is the best fit; all three processes share a common trait, which is applying coatings that are resistant to corrosion and chemicals. Once we know which coating process provides the most effective solution, we will move on to select the suitable types of coating and materials.

In most cases, inert ceramic or sacrificial metal alloy materials/coatings are selected as they can protect various industrial equipment and components exposed to risks of oxidation induced deterioration or chemical action. In the thermal spraying industry, aluminum and zinc coatings are nicknamed as ‘sacrificial coatings’. These coatings do deteriorate over time, but at a much slower rate compared to the substrate that is being protected by them.
