Why Floor Coating is so much important?

Epoxy Curing Agent

There are a variety of applications for epoxy-based materials in market that includes coatings, adhesives and the creation of composite materials. It is important to know that the materials used for surface coatings are known for their good mechanical properties, electrical insulating properties, adhesion, and chemical- and heat-resistance.

From protecting pipelines to sealing warehouse floors, an epoxy surface coating protects surfaces strengthens materials and protects them from corrosion and decay, making epoxy one of the most widely used industrial finishes.

While epoxy coatings may initially cost more than other types of surface coating materials, its ability to provide superior and durable corrosion resistance, adhesion and flexibility to a variety surfaces ultimately makes it a more economical choice, as the need to reapply the coating may be less frequent when materials are prepared well.

There are different types of systems used for floor coating and most of them work well if the surface is properly prepared for the coatings. But today’s major problem is preparation of the surface before coating. Phenalkamines works well when they are used as curing agents made with epoxy system for primer coat. On the moist concrete too.

The role of primer is to protect the surface and also to give good bonding between moist surface to primer coat and primer coat to topcoat. Phenalkamine due to chemical structure provides very good adhesion on the moist surface and also it allows the topcoat to bond well with primer. For any primer coating two important criteria are sealing and adhesion, phenalkamine cured with epoxy resin primer provides both the advantages. Top of it they also provide added advantage of 100% solid content.

When phenalkamine based primer was applied on wet concrete surface and pull of test was done after 7 days of coating the high cohesive strength was found. Also when primer was applied on damp or humid surface no blistering was found on the surface of the coatings. This shows that phenalkamines are not humidity sensitive. In normal case the primer coating is done on green concrete (wet concrete) after 28 days of drying, but in case of phenalkamines you can coat primer immediately, thereby saving the time of floor coating.

Epoxy Surface Coating Considerations

Epoxy coatings require specific environmental conditions to ensure the success of their application, as well as the proper preparation of the respective surfaces. When applying an epoxy coating to steel, for instance, you may need to remove the thin corrosion layer that naturally forms on the surface. Methods of cleaning surfaces include the use of chemicals or blasting products.

After you prepare and clean a surface, it becomes vulnerable to environmental contamination. When working with steel, for example, it takes as little as 30 minutes for flash rust to form. The longer you wait to apply an epoxy surface coating, the shorter the expected field longevity becomes. For this reason, manufacturers provide specific instructions regarding how quickly to apply the first coating and the ideal environmental conditions.

The success of a protective epoxy coating depends on the surface’s cleaning and preparation, as well as the ambient conditions to which the surface is exposed during the preparation, application and curing periods. When a controlled environment, such as a factory, isn’t available, professionals look to temporary climate control solutions to create the ideal ambient conditions for every step of the epoxy surface coating process.
