Waterborne epoxy coating is a coating with water as solvent or dispersion medium. Waterborne epoxy coatings, including water soluble epoxy coatings and water emulsion coatings. Water soluble coatings are often referred to as electrophoretic coating, that is, when the resin is dissolved in water to form a uniform colloidal solution, if the resin ion with charge, under the action of direct current, the colloidal particles can be deposited on the surface of the workpiece.
Advantages: 1, water based epoxy paint provincial resources, low pollution waterborne epoxy coatings with water instead of organic solvents. Water based epoxy paint is a source of water, can save a lot of resources, in the process of production, transportation, coating, basically no pollution, no fire hazard, so it is beneficial to protect the ecological environment.

2, waterborne epoxy paint coated surface of the object by removing oil and rust, phosphating, not completely dry coating. The surface treatment of the coated article has more strict requirements for the water - based epoxy paint when it is used as an electric deposition. Construction equipment, tools can be washed with water.
3, the waterborne epoxy resin coatings by electrodeposition electrophoretic coating automatic construction method, spray, brush, spray, dip and other construction methods is higher than that of the coating efficiency, stable quality, produce less coating defects; other waterborne epoxy paint can be sprayed, brush, dip and other construction methods.
4, there are a large number of hydrophilic groups in waterborne epoxy coatings, and the corrosion resistance of the coating should be improved. Effective measures should be taken to ensure that the water in the film is released within the specified time. This is a topic which is worth paying attention to in the formula design, production and coating process of waterborne epoxy coatings.

In early 90s 80s, the introduction of foreign floor paint technology, and gradually by the Chinese paint research institutes and enterprises to introduce, absorb and improve the formation of the Chinese characteristics of the floor paint market. With the rapid development of China's economy, especially the rapid growth of pharmaceutical, chemical, electronics and other industries, driven by the rapid growth of industry market floor paint, floor paint varieties are also increasingly rich, continuously improve product performance. In recent years, floor paint products environmental protection gradually get attention, floor paint, solvent free water rapidly and quickly accepted by the market. No solvent or high solid floor paint is widely used in the coating system. Waterborne epoxy floor paint has been mature products, but the price is relatively high, with the development of technology, and gradually replace the solvent based floor paint market.
Classification of epoxy anticorrosive floor paint
1 according to the dispersion medium can be divided into: water-based floor paint, solvent floor paint, solvent based floor paint
2 according to the thickness can be divided into; floor primer, thin coating Floor paint, self leveling floor paint
3 according to the film can be divided into: epoxy floor paint, polyurethane floor paint, acrylic floor paint, alkyd floor paint, vinyl flooring paint, rubber floor paint
