Since the main characteristic epoxy floor paint film-forming binder is an epoxy resin, an epoxy resin itself has a thermoplastic, or a fatty acid with a curing agent needs to react, cross-linked macromolecular network structure, the thermoplastic from itself becomes thermosetting, thus demonstrating the excellent performance. Epoxy paints are many different characteristics performance. 1. Excellent adhesion: Epoxy coating has many hydroxyl and ether bond with the substrate material can absorb it. And the volume shrinkage when cured epoxy resin is low (only about 2%), so the film of metal (steel, aluminum), ceramics, glass, concrete, wood and other polar substrates have excellent adhesion. 2. Excellent chemical resistance: epoxy resin, only a hydrocarbon and ether linkages, no ester bond, so alkali resistance particularly prominent, the general anti-rust oil or alkyd primer. When the cathode portion alkaline etching, can be saponified destroyed. Epoxy paint adhesion and alkali, it can be widely used as anti-corrosion primer. Because after a bad paint curing epoxy to form a three-dimensional network structure, and the ability of dipping oils can also be used extensively for corrosion tanks, tankers, aircraft integral fuel tank lining the inner wall and the like. 3. Toughness: Compared with thermosetting phenolic resin coatings, epoxy floor coatings containing aromatic rings and hard, with a rotating ether bond facilitates the molecular chain, has a certain toughness, unlike brittle phenolic resin (pitch than its crosslinked Short epoxy). Crosslinked epoxy long distance, easy internal rotation, the greater the molecular weight of the epoxy crosslinking spacing greater. 4: Epoxy wet surfaces have a certain wetting force, particularly when using the polyamide resin as a curing agent, the coating can be made underwater construction, can squeeze out the water surface (10) coated, can be used for underwater structures corrosion repair and construction of underwater structures. 5: Molecular epoxy resin itself is not high, can meet a variety of manufacturing and curing agent solvent-free, high-solids coatings and powder coatings, environmental compliance, and can get thick coating. 6: an epoxy resin having an epoxy group and two hydroxyl reactive groups, with polyamines, with a polyamide resin, phenol resin, amino resin, polyisocyanate, etc. to prepare a variety of coatings, either dried at room temperature, hot cocoa baking, to meet different construction requirements. 7: epoxy resin has excellent electrical insulating properties, can be used to seal the pouring, dipping paint. Epoxy has many advantages, but there are not enough, this place is its poor photoaging. Epoxy resins containing aromatic ether bond, the film by sunlight (UV) irradiation after scission readily biodegradable, so poor outdoor durability. It is usually intolerant of bisphenol A epoxy resin outdoor sunlight, volatile photochromic film, then chalking, should not be used outside of the finish.
