Among the many components in the building industry for many years is the formulation of epoxy. And since we usually use this material in floor applications, it is important then that we know some matters about epoxy floor coatings.
The key behind high performing epoxy coatings are the epoxy resins which form as the core materials in formulating quality epoxy based primers, top coats and sealants. The epoxy floor coatings will perform well on floor finishes, as protective coats, as fire retardants, as a waterproofing coat, and contribute to damage resistance paints, all because of these resins.
Know that epoxy coatings can practically be applied in several types of surface, like concrete, steel and other surfaces. Depending on the kind of material used for the substrate, specific coating system may be dictated, but not in the case of epoxy floor coatings where application is possible in nearly all kinds of surfaces.
Epoxy resin molecules are almost not penetrable because its compounds of bisphenol A and epichlorohydrin organochlorine/epoxide are cross linked, and the chemistry leads to a floor coating that is highly water, chemical or air intrusion resistance, thereby the coating has the ability to prevent corrosion in metal or concrete surfaces.
Other common coating systems are developed together with epoxy, like epoxy amine systems, epoxy sulfide systems, aliphatic epoxy systems and hybrid epoxy systems, that when combined with epoxies, you can obtain the glossy appearance of surface, and there is better adhesion and curing time, thus an increased performance of the material. Alkyds and acrylics can also combine well with the epoxy coating systems to further improve its performance.
Since epoxy coatings are resistant to several kinds of damages, it is often applied to areas with heavy duty floors like those of manufacturing plants, warehouse floors, heavy machinery garages, and airplane hangars.
The strong adhesive capabilities of epoxy based coatings, which is 1.5 thousand pounds per square inch of flooring of adhesive power, would lead to floors in good condition and can remain intact for long periods of time even if the floors are exposed to intense physical loads.
Epoxy floor coatings contain pigments that will expand fast when there is exposure to heat, making the coatings good fire retardants. There is a thick barrier that is formed as the expansion of pigments occur, and this allow for time until the fire is put off naturally or by the fire-fighting team.
Further, what makes epoxy floor coatings more effective in several surfaces is its property of being either water borne, high solids or solvent borne.
Because of the inherent chemical properties of epoxy, it gives a high performance and versatility of epoxy floor coatings, and remain to be the most popular coating systems that can meet any kind of coating application requirements.
