How about epoxy floor paint?

How about epoxy floor paint? This problem can't be generalized, but should be analyzed according to your specific situation. The following briefly introduces the characteristics of epoxy floor paint for your reference. Because the main film-forming base material of epoxy floor paint is epoxy resin, and epoxy resin itself is thermoplastic, it needs to react with curing agent or fatty acid to cross-link into reticular macromolecules, which changes from thermoplastic to thermosetting, thus showing various excellent properties. There are many epoxy floor coatings with different properties. 1. Excellent adhesion: Epoxy floor paint has many hydroxyl and ether bonds, which can be adsorbed with the substrate. Moreover, the volume shrinkage of epoxy resin during curing is low (only about 2%), so the paint film has excellent adhesion to polar substrates such as metal (steel, aluminum), ceramics, glass, concrete and wood. 2. Excellent chemical resistance: epoxy resin has only alkyl and ether bonds, but no ester bonds, so its alkali resistance is particularly prominent, and it is a general oily or alkyd antirust primer. In the process of corrosion, the cathode is alkaline and will be destroyed by saponification. Epoxy floor coating is alkali-resistant and has good adhesion, and can be widely used as anti-corrosion primer. In addition, because the cured epoxy ground damage coating has a three-dimensional network structure, it can also resist the impregnation of oil, and can also be widely used for the corrosion protection of oil tanks, oil tankers, the inner wall lining of aircraft integrated fuel tanks, etc. 3. Good toughness: Compared with thermosetting phenolic resin coatings, epoxy floor coatings contain aromatic rings, are hard, have ether bonds to facilitate the rotation of molecular chains, and have certain toughness, unlike phenolic resins, which are fragile (because their cross-linking spacing is shorter than that of epoxy resins). Epoxy resin has a long cross-linking space and is convenient for internal rotation. The larger the molecular weight of epoxy resin, the larger the cross-linking space. 4. Epoxy resin has a certain wetting force on the wetted surface, especially when polyamide resin is used as curing agent, it can be made into underwater construction coating, which can squeeze out the water on the surface of the object and can be used for emergency repair and anti-corrosion construction of underwater structures. 5. Epoxy resin itself has low molecular weight, and can be made into solvent-free and high-solid powder coatings and water-based coatings with various curing agents, which meets the requirements of environmental protection and can obtain thick film coatings. 6. Epoxy resin contains two active groups, epoxy group and hydroxyl group, which can be combined with polyamine, polyamide resin, phenolic resin, amino resin and polyisocyanate to make various coatings, which can be dried at room temperature and baked at high temperature to meet different construction requirements. 7. Epoxy resin has excellent electrical insulation performance, which can be used for pouring sealing and impregnating paint. Epoxy resin has many advantages, but it also has some disadvantages, such as poor photoaging. Epoxy resin contains aromatic ether bonds, and the paint film is easy to degrade and break after being irradiated by sunlight (ultraviolet rays), so the outdoor weather resistance is poor. Therefore, the usual bisphenol A epoxy resin is not resistant to outdoor sunlight, and the paint film is easy to change color and then powder, so it is not suitable for outdoor topcoat.
