Not many people give much thought to the fact that almost every object you touch as you go about your day had to be manufactured by someone. When you stop to consider the impact that the processing and manufacturing industry has had on the modern world, it can blow your mind. My mind was blown when my son arrived home from his new job at a local processing and manufacturing plant and told me about the industry he was now working in. Since then, I have learnt all kinds of cool things which I would love to be able to share with the rest of the world.

Powder coatings come in handy for many different industrial applications. One of the most important applications of powder coatings is in providing chemical resistance. Equipment such as storage tanks, pipes and pumps are often subjected to both acidic and alkaline conditions that may weaken the machines over time.
Without a durable and chemically resistant coating, such equipment would be incapable of operating in harsh chemical environments. There are many different types of coatings used to provide chemical resistance. When selecting one for your industry, make sure the coating has the following characteristics.
1. Abrasive strength
First off, your chemically resistant coating material needs to provide abrasive strength. In many chemical environments, your equipment may come in contact with liquids and other components that brush against its surface.
If the coating is incapable of providing abrasive protection, it will easily get worn out and expose the underlying surfaces of your machines. Make sure your coating can withstand high impact without chipping out of place. Dry film powder coatings are a good option to consider.
2. High melting point
Temperature tolerance is also an important part of a chemically resistant coating. If the coating material can't withstand a large temperature range, it may lose its chemical resistance at a particular point.
The coating should be capable of withstanding both negative and positive temperature conditions. For example, polytetrafluoroethylene (commonly referred to as PTFE) is a relatively common coating that provides high-temperature tolerance. Its ability to do so is primarily because it has a very high melting point. As a result, your pipes, valves and pumps remain protected even when things get hot.
3. A Thin, dry layer
Chemical resistance is best achieved by a thin, dry-film layer that doesn't expose underlying materials to chemical reactions. This is why powder coatings are the preferred option for chemical resistance than wet paint.
The dry film layer sticks firmly in place and does not provide any moisture to react with acids or bases in the external environment. Make sure your chemically resistant coatings are applied in a thin and dry layer.
4. Corrosive resistance
Corrosion, in itself, is a chemical reaction. A chemically resistant coating should be both resistant to corrosion and other materials that may wear out your equipment. Your coating also should stick firmly to applied surfaces and remain resistant to moisture and abrasion.
FEP coatings (made from ethylene and polypropylene) are known to provide excellent corrosion and chemical resistance. They're also applied as a thin, lubricated layer that sticks firmly to your equipment.
