The Ultimate Guide to Chemical Resistant Coatings
We’ve all heard the term “chemical resistant coating” used before. It’s a blanket term that refers to any type of finish used on a piece of equipment that protects it from chemical exposure. There are a number of different chemicals that can negatively impact the functionality and life of your equipment, as well as your work environment. This applies to many industries, but is especially important for those using manufacturing plants or other production facilities where chemicals are present. Chemical resistant coatings can protect metal surfaces from corrosion, prevent hazardous materials from interacting with them, and even neutralise some types of dangerous substances. They are also widely available in numerous colours and textures so you can tailor their appearance to suit your specific needs. The following guide covers everything you need to know about chemical resistant coatings and which one may be right for you.
What is a Chemical Resistant Coating?
The term “chemical resistant coating” refers to a finish used on equipment that protects it from chemical exposure. There are a number of different chemicals that can negatively impact the functionality and life of your equipment, as well as your work environment. This applies to many industries, but is especially important for those using manufacturing plants or other production facilities where chemicals are present. Chemical resistant coatings can protect metal surfaces from corrosion, prevent hazardous materials from interacting with them, and even neutralise some types of dangerous substances. They are also widely available in numerous colours and textures so you can tailor their appearance to suit your specific needs. The following guide covers everything you need to know about chemical resistant coatings and which one may be right for you.
Types of Chemical Resistant Coating
There are three main types of chemical resistant coatings that most commonly fit the bill for protecting equipment from harsh chemicals. They are epoxy, polyurethane, and polyester. Depending on your specific needs, one of these may be the best option. You should also be aware that two of these types are typically solvent based, while epoxy is water-based. This can be an important distinction, especially if you need to use your equipment in an area that already has poor ventilation. – Epoxy: Epoxy has been used as a chemical resistant coating for decades. It is primarily used on smaller pieces of equipment, such as drums and containers, that are subjected to high levels of chemical exposure. It is also often used to seal off pipes and fittings that are exposed to chemicals. It is a two-part system that requires thorough mixing ahead of application. It is also available with a wide range of viscosities so you can select a formulation that is appropriate for the type of equipment you are working with. – Polyurethane: Polyurethane is a particularly durable and long-lasting option for chemical resistant coatings. It is often applied to large pieces of equipment, such as tanks and storage vessels, that are exposed to a wide range of harsh chemicals. It is also commonly used to protect large machinery, such as conveyor belts and turbines, that are in close proximity to chemicals. While it may not be appropriate for uses that require a sealant, it is a great option for general purposes. – Polyester: Polyester is a very commonly used option for chemical resistant coatings. It is a versatile material that can be applied to a wide range of equipment and other items, including structural materials like concrete. It is often used to line the inside of tanks and vessels, as well as process equipment like piping. It is available in both solvent-based and water-based formulations, though many water-based options are suitable for outdoor use.
Why Install a Chemical Resistant Coating?
Essentially, chemical resistant coatings are designed to protect the metal surface beneath them from corrosion and/or other chemical damage. They also play a critical role in ensuring that the surface is safe for personnel. Some chemicals are either toxic or flammable in their pure state, while others can react to metal surfaces, causing corrosion. To prevent this, it is necessary to install a protective coating that can prevent the chemicals from coming into contact with the metal. Chemical resistant coatings can also be used to seal off tanks or vessels that contain chemicals. This is often used in the petrochemical industry, where large tanks and vessels are filled with a wide range of chemicals. This is especially important if there is a risk that the chemicals could find their way into the environment or cause damage to nearby equipment.
How to Find the Right Chemical Resistant Coating?
Finding the right chemical resistant coating for your application can be challenging, but there are a few things you can do to help narrow down your options. The first thing to do is to identify the chemicals that you need protection from. This is particularly important if the chemicals you need protection from are hazardous. Many coatings are designed to resist common chemicals, but few are designed to protect against dangerous substances such as acids or bases. Once you know the types of chemicals you need protection from, you will also want to decide what type of finish you want. You can find a wide range of finishes, including glossy, semi-gloss, and non-glossy textures, as well as a variety of colours. You can also find a few specialty types that are specially formulated for marine use or indoor use.
Conclusion
Chemical resistant coatings are designed to protect the metal surface beneath them from corrosion and/or other chemical damage. They also play a critical role in ensuring that the surface is safe for personnel. Some chemicals are either toxic or flammable in their pure state, while others can react to metal surfaces, causing corrosion. To prevent this, it is necessary to install a protective coating that can prevent the chemicals from coming into contact with the metal. When identifying what type of coating is best for your application, it is important to consider the chemicals you need protection from, as well as the finish you want. You can also find a variety of specialty coatings for applications like marine use or indoor use. With the right coating, you can have confidence that your equipment and surfaces will be protected from hazardous chemicals.
