Features of Floor Coating

Floor coatings are typically composed of epoxy resin, solvents, curing agents, pigments, and additives. This category includes many types of floor coatings, such as solvent-free self-leveling floor coatings, anti-corrosion floor coatings, wear-resistant floor coatings, anti-static floor coatings, and water-based floor coatings.

Its main characteristics include strong adhesion to cement substrates, resistance to water and other corrosive media, and excellent physical and mechanical properties of the coating film. It is suitable for various ground surfaces in factories, repair shops, sports fields, parking lots, warehouses, shopping malls, and other similar locations.

Epoxy flooring, also known as epoxy resin flooring, epoxy resin flooring, or epoxy flooring, has seen wider application in garages in recent years due to its promotion and development. This results in cleaner, dust-free, slip-resistant, wear-resistant, and aesthetically pleasing underground garages in many residential projects.

The characteristics of epoxy floor coatings are: First, excellent adhesion. Epoxy floor coatings contain many hydroxyl and ether bonds, allowing them to adhere well to the substrate. Furthermore, epoxy resin has a low volume shrinkage rate during curing (only about 2%), resulting in excellent adhesion to polar substrates such as metals (steel, aluminum), ceramics, glass, concrete, and wood. Second, excellent chemical resistance. Epoxy resin contains only hydrocarbon groups and ether bonds, lacking ester bonds, making it particularly alkali-resistant. General oil-based or alkyd anti-rust primers, when exposed to alkaline conditions at the cathode during corrosion, are saponified and destroyed. Epoxy floor coatings, with their alkali resistance and good adhesion, can be widely used as anti-corrosion primers. Furthermore, because epoxy floor coatings form a three-dimensional network structure after curing and are resistant to oil immersion, they can be widely used for corrosion protection of oil tanks, tankers, and the inner lining of aircraft fuel tanks.

Third, they have good toughness. Compared with thermosetting phenolic resin coatings, epoxy floor coatings contain aromatic rings and are harder, and the ether bonds facilitate molecular chain rotation, giving them a certain degree of toughness, unlike phenolic resins which are brittle (because their crosslinking spacing is shorter than that of epoxy resins). Epoxy resins have a longer crosslinking spacing, facilitating internal rotation; the larger the molecular weight of the epoxy resin, the larger the crosslinking spacing.

Fourth, they are waterproof and corrosion-resistant. Epoxy resins have a certain wetting power on wet surfaces, especially when using polyamide resins as curing agents. They can be formulated into underwater construction coatings that can displace water from the surface of objects for application, and can be used for emergency repairs and corrosion protection of underwater structures.
