Differentiating 3 Common Types of Chemical Resistant Coatings

Virtually all industrial equipment and components are subject to chemical exposure, most likely in the form of liquid spillages. While exposure to mild chemicals for a short time won’t necessarily harm a coated surface, prolonged exposure certainly will. This is why chemical resistant coatings have been specially designed to combat the adverse impacts of strong solvents and chemicals and protect equipment and components from potential damage.

There are different types of chemical resistant coatings, and choosing the right one for your facility’s equipment will depend on several factors. These factors include the which specific chemical your equipment is being exposed to, the amount of that exposure, and the kind of preparation needed in order for the substrate to be successfully coated.

Here are 3 common chemical resistant coatings that you may consider for application in your facility or business:

Acrylic coating

Also referred to as polyurethane, this coating system provides the weakest resistance against chemicals but is a good option if you want to better maintain the aesthetic while still achieving some protection for your products. It is typically used in applications where it can serve as a topcoat for epoxy primer, which will provide enhanced chemical resistance.

Epoxy coating

Generally, epoxies provide the strongest protection and resistance against a wide range of chemicals. They can also be modified to offer more resistance from specific chemicals. The catch is that they usually have poorer UV resistance. Also, if you’re specifically looking for chemical resistant coatings that have greater aesthetic appeal, epoxy may not be your top option.

Epoxy phenolic coating

This coating system is one of the variations of the regular epoxy coating. It provides extreme chemical resistance but weaker protection against weather elements. This type of coating is normally used as an interior coating, such an internal tank lining. It can also be modified to better adapt to the specific chemical it is meant to be protecting against.

Chemicals are so versatile and modifiable that there is bound to be a perfect solution for your specific needs. At Teff-Line, we are committed to helping you choose the best system for the protection of your equipment, and you can rest assured that our experts will be there with you throughout the process to help you make crucial decisions about chemical resistant coatings.
