Vinyl resin anti-corrosion coatings are composed of vinyl ester resins, reactive diluents, fillers, initiators, and accelerators. Vinyl ester resin is a kind of resin obtained by a ring-opening esterification reaction of acrylic acid or methacrylic acid and epoxy resin. The process performance of vinyl ester resin is similar to that of unsaturated polyester resin, and its chemical properties are similar to that of epoxy resin. After research, the ester group of vinyl ester resin only appears at the end of the main chain, which greatly enhances the performance of vinyl ester resin. With water resistance, heat resistance,  and corrosion resistance, it is an excellent matrix for making composite anti-corrosion materials.

Vinyl heavy-duty anti-corrosion coatings have excellent adhesion to metal and concrete substrates, extensive acid and alkali resistance, salt water resistance, high-temperature resistance, low-temperature curing, fatigue resistance, and other excellent mechanical properties and toughness, as well as deicing ester resistance Almost all inorganic acids except acids, the coating is durable. Vinyl heavy-duty anti-corrosion coatings can freely adjust the curing time and viscosity and are easy to apply. Under 1000 degrees, they can resist the erosion of most acid-base salts and other chemical agents. They have long-term anti-corrosion life and can be used under harsh conditions. Vinyl heavy-duty floor coatings can generally be used for 10 or 15 years in chemical atmospheres and marine environments and can be used for more than 5 years even in acid, alkali, salt, and solvent media and under certain temperature conditions.

The price of vinyl resin anticorrosive paint is about tens of yuan per square meter, the cheap one is more than ten or twenty yuan, and the expensive one is one or two hundred yuan. With different uses of vinyl resin anticorrosive paint, the price is not the same. In terms of usage, it is used as a heavy-duty anti-corrosion coating for equipment, pipelines, and floor structures that are in direct contact with corrosive media in harsh environments.

Vinyl heavy-duty anti-corrosion floor paint is a kind of floor paint with high wear resistance and high corrosion resistance produced to adapt to the harsh working environment of modern industry. Thick film is an important symbol of heavy-duty anti-corrosion floor paint. The dry film thickness of general anti-corrosion coatings is about 100 μm or 150 μm, while the dry film thickness of heavy-duty anti-corrosion coatings is 200 μm or more than 300 μm, and there are 500 μm to 1000 μm, even as high as 2000 μm.

The following are the influencing factors of vinyl heavy-duty floor coatings
1. The influence of the compatibility of vinyl resin and color paste on the performance of paint film. Vinyl heavy-duty anti-corrosion coatings have fast response and large shrinkage. If the compatibility between the vinyl resin and the color paste is poor, it will not only affect the full curing of the paint, but also easily cause floating and blooming. Choosing the right vinyl resin and color paste can effectively reduce the phenomenon of floating color and blooming of the paint film. Choosing resins and color pastes with good compatibility can greatly improve the anti-corrosion performance of the product and the performance of the coating film. The amount of vinyl color paste will affect the hardness and corrosion resistance of the coating film, and the appropriate amount of vinyl color paste should be selected to ensure the comprehensive performance of the coating.
2. The effect of the type and amount of wax liquid on the appearance and corrosion resistance of the coating film. In vinyl heavy-duty anti-corrosion floor paint, the type and amount of wax liquid have a significant impact on the coating performance of vinyl heavy-duty anti-corrosion coatings. The appropriate type and amount of wax liquid are conducive to ensuring the performance and corrosion resistance of the coating film.
3. The influence of additives on the properties of vinyl heavy-duty anti-corrosion floor coatings. Vinyl heavy-duty anti-corrosion floor coatings formulated with different wetting and dispersing agents have different film appearances.
4. The influence of defoamer. Vinyl heavy-duty anti-corrosion coatings have a large reaction shrinkage rate and rapid viscosity rise and are more difficult to defoam than ordinary anti-corrosion coatings. Therefore, it is more important to choose the appropriate type and amount of defoamer. Choosing the type and amount of wetting and dispersing agent, defoamer, and leveling agent suitable for the vinyl heavy-duty anti-corrosion coating system can effectively reduce the phenomenon of floating color, pinhole, and poor leveling of the coating film.
