Epoxy Paint

Description

​

Solid epoxy is created when epoxy resin, also known as polyepoxide,  is cured using one of several dozen chemicals. It forms a polymer that bonds with the prepared substrate. In the mixing stage, it  can have pigments or other elements added to it so that it can have a similar appearance to standard latex paint, or resemble other materials such as stone or composite. The hard surface created by the paint is a sturdy protectant for the substrate it is applied to. Because the material can have elements added to create texture, or can be applied with tools that leave a texture on its surface, it is also useful to provide a slip-resistant surface.

​

Epoxy paints possess many other useful properties, including bacteria resistance, durability, chemical resistance, moisture impermeability, solvent resistance, ease of sanitation, protection against abrasion and temperature, and versatility of texture. Because of these qualities, it is frequently used in restaurants, hospitals, labs, garages, kitchens, and industrial environments. Most state health departments require that commercial food preparation areas have an epoxy tile or epoxy floor coating to meet code.

​

The polymer chain of finished epoxy is affected by UV light, so epoxy paint exposed to repeated sunlight will yellow over time. This can be avoided by filtering out UV light coming into the space, coating the surface with a UV filtering sealant, or by choosing epoxy paint with UV-resistant additives.

Environmental Impact

Two-part epoxy coatings can be used as a heavy duty treatment for industrial metal substrates, and require significantly less heat energy than a powder coating alternative. It is a resistant finish, if applied and catalyzed properly, that can endure years of heavy duty wear and tear. If the surface begins to have more serious wear, it can be resurfaced, alleviating the need for a brand new installation. Epoxy paint surfaces can be cleaned with a mild soap and water.

​

Epoxy application carries chemical exposure risks. Exposure can affect skin, nose, throat, lungs and cause asthma-like symptoms or breathing difficulties. These usually arise from direct contact, or from inhalation. Exposure to some of the chemicals in epoxy has also been linked to detrimental health effects in pregnant women. OSHA requires that all epoxy products come with a Safety Data Sheet outlining the proper precautions and procedures to use when applying the product.

​

Because of epoxy’s non-porous nature, it is resistant to microbial growth, and easy to clean up, if organic matter is spilled on it. This can enhance the sanitation of various spaces, particularly in healthcare environments, and food preparation areas. For places that frequently encounter water, epoxy paints on the floors and walls can help prevent harmful mold and mildew growth.
