Zhongshan Epoxy Floor Coating Since the main film-forming base material is epoxy resin, epoxy resin itself has thermoplasticity, needs to react with curing agent or fatty acid, cross-linked into a macromolecular network structure, from its own thermoplastic change For thermosetting, it shows a variety of excellent properties. Epoxy floor coatings are many and their properties are different.

1. Excellent adhesion: Epoxy floor coating has many hydroxyl and ether bonds, so it can be adsorbed with the bottom material. Moreover, when the epoxy resin is cured, the volume shrinkage is low (only about 2%), so the paint film has excellent adhesion to metal (steel, aluminum), ceramics, glass, concrete, wood and other polar substrates.

2. Excellent chemical resistance: Epoxy resin has only hydrocarbon group and ether bond and no ester bond, so the alkali resistance is especially prominent, and general oily or alkyd anti-rust primer. In the case of corrosion, the cathode site is alkaline and will be destroyed by saponification. Epoxy floor coatings are alkali-resistant and have good adhesion, so they can be used in large quantities as anti-corrosion primers. Because epoxy paint is cured, it has a three-dimensional network structure after being cured, and can be impregnated with oil. It can also be widely used for anticorrosion of oil tanks, oil tanks, and aircraft's overall tank inner wall linings.

3. Good toughness: Compared with thermosetting phenolic resin coatings, epoxy floor coatings contain aromatic rings and are hard, with ether bonds to facilitate the rotation of the molecular chains, have a certain toughness, unlike phenolic resin is very brittle (because of its cross-linking spacing ratio Short epoxy). Epoxy resin has a long cross-linking distance and facilitates internal rotation. The greater the molecular weight of the epoxy resin, the greater the cross-linking distance.

4: Epoxy resin has a certain wetting force on the wet surface, especially when polyamide resin is used as a curing agent, it can be made into underwater construction coating and can be applied to the surface of the object to be coated and can be used in underwater structures. Repair and corrosion protection of underwater structures.

5: The molecular weight of epoxy resin itself is not high, can be combined with various curing agents to produce solvent-free, high solids powder coatings and water-based coatings, in line with environmental requirements, and can obtain thick film coating.

6: Epoxy resin contains two reactive groups: epoxy group and hydroxyl group. It can be combined with polyamines, polyamide resins, phenolic resins, amino resins, polyisocyanates, etc. to make a variety of coatings, which can be dried at room temperature and high temperature Baking to meet different construction requirements.

7: Epoxy resin has excellent electrical insulation properties and can be used to seal and dip paint. Epoxy resins have many advantages, but there are also disadvantages, and their photoaging properties are poor. Epoxy resin contains aromatic ether bonds, and the film is easily degraded after exposure to sunlight (ultraviolet rays), so outdoor weatherability is poor. Therefore, the common bisphenol A epoxy resin is not resistant to outdoor sun exposure, and the paint film is easily discolored and discolored, and then it is powdered and should not be used as an outdoor finish.
