Affordable Fusion Bonded Epoxy Coating
Green Epoxy Coatings
One of the most environmentally-friendly methods of protective coating is epoxy coating, that is a product of pure, organic resin. Resin, which often comes from coniferous trees and plants, is valued for its ability to synthesize chemically and become useful products like varnish, adhesives, perfumes, and epoxy coating, amongst others.

Epoxy resin is manufactured by way of a procedure for polymerization. The organic epoxy resin is combined with catalyzing agents, fillers, and pigments to show right into a dry powder which, when heated, melts and causes a reaction which allows the forming of complex cross-linked polymers. Once cured and dried, epoxy coating provides strong, UV-resistant, and permanent protection to steel materials.

Fusion-Bonded Epoxy (FBE) Coating

Fusion-bonded epoxy coating is a approach to applying corrosion-protective epoxy coating to steel pipes, rebars (reinforcement bars), pipes and valves. Epoxy powder is melted at temperature ranges of between 180 to 250�C (360 to 480 �F), and transforms right into a liquid element that flows and adheres in to the steel surface. After the liquid powder dries, it cross-links or "fusion-bonds" to the surface of the steel material permanently, protecting the steel structure effectively and permanently.

Fusion-bonded epoxy coatings are used extensively in industries requiring steel pipes and fittings which are corrosion-free. Because aro pipe coating is manufactured out of environmentally-friendly materials, structures with epoxy coatings do not contain environmentally-hazardous solvents or substances which will come off and cause safe practices risks.


The Epoxy Coating Process

Epoxy coating plants commonly coat bars which are pre-cut in straight lengths of around 40 to 60 feet. The bars are then cut and bent to meet up project specifications. The bars are carried by way of a conveyor system and subjected to the epoxy coating process.

To prepare steel surfaces for the epoxy coating process, blast cleaning is performed to remove rust, scales and other contaminants from the steel surface. The end result of blast cleaning is really a rough surface finish called a profile. The profile increases the effective surface area of the steel and provides better anchorage for epoxy coating when it's later applied to the steel bar.

Blast cleaning involves the release of compressed air to the steel surface, propelling abrasives like steel grit, garnet, or coal slag to hit the surface, bringing on pock marks that cleanses and roughens the surface.

After the rebars have been blast-cleaned, they're heated and sprayed with dry epoxy powder. When dry epoxy powder is ejected from spray nozzles they are imparted with electrical charges that are automatically attracted to the already grounded heated bars. The dry powder melts and flows into the steel's heated surface, anchoring to the ribs and deformations in the surface. Heat also induces a chemical reaction that transforms the epoxy powder molecules into complex cross-linked polymers, forever changing the material into its final state.

A 30-second curing process solidifies the epoxy coating, having an air or water quench introduced to reduce the temperature quicker for easy handling.

The process of manufacturing epoxy coating, and the coating process itself, are efficient and environment-safe, with little material lost to the atmosphere, even lesser waste, and zero contaminants. pipeline coating companies to environmental consideration also to adhere to environmental safety standards, epoxy coating remain a viable choice to protective coating.
