Epoxy floor coating coatings have excellent adhesion mainly determined by the molecular structure of the epoxy resin and its curing reaction characteristics. Epoxy resin flooring epoxy resin in the molecular structure of epoxy terminal groups, base groups and ether bonds and Other polar groups, the presence of these groups so that the epoxy resin molecules and adjacent interfaces to produce electromagnetic adsorption or chemical bond Therefore, the coating of epoxy floor paint can produce strong adhesion to the surface of metal, wood, concrete and other substrates. Epoxy floor paints produce lower internal stress in cross-linked and cured films: During the film formation process of epoxy floor paints, many factors can cause the coating film stress of the floor paint to cause coating. The final defects of the film, especially the reduction of the adhesion of the coating film to the substrate. Epoxy resin molecules contain secondary light bases, and some bases are derived from curing. Hydrogen bonds are formed between the light bases and the epoxy molecules are arranged closely. Therefore, the epoxy resin has less difference in density before and after curing. , And the epoxy resin curing reaction is mainly a gradual ring-opening addition polymerization reaction, in the reaction there is no formation of small molecule by-products, so the curing shrinkage of epoxy resin is very low, so the epoxy resin coating is cured in the film It has little effect on the adhesion between the coating/interface. Moreover, the backbone of bisphenol A epoxy resin contains many ether bonds. The ether bond and carbon-carbon bond make the epoxy macromolecular chain have a certain flexibility, which facilitates the rotation of the molecular chain and eliminates some of the internal stress. Epoxy mortar floor specific practices and requirements Undercoat 1. Use solvent-based epoxy one-component primer or solvent-free epoxy primer (main paint: curing agent = 5:1) to mix and stir; 2. Brush evenly with rollers and brushes without any paint leakage. 0.15-0.20Kg/m2 Coated mortar 1. Use solvent-based epoxy midcoat (1:1) or solvent-free epoxy midcoat (5:1) to mix and add appropriate amount of 40- to 100-mesh quartz sand to mix well; 2. With a batch knife full scrape 1 to 2 times; 3. After curing, grind and remove defects such as knife marks and clean them. 0.7kg/m2/mm Putty layer 1. Use solvent-based epoxy midcoat (1:1) or solvent-free epoxy midcoat (5:1) to mix and add appropriate amount of filler (such as quartz powder and talcum powder) and mix well; 2. Approved with a batch knife 1 to 2 times, focusing on filling holes in the ground; 3. After curing, grind the defects such as knife mark, and clean it with a vacuum cleaner, chicken feather zen, wrung wet towel and so on. 0.2-0.30 kg/m2 Top coat 1. Use a solvent-based epoxy topcoat (1:1) or a solvent-free epoxy topcoat (5:1) to mix in proportion and stir evenly. 2. Dip the top coat with the prepared roller and roll it evenly. The coating is required to be even and no leakage is applied. 0.25-0.30 kg/m2 Wear layer 1. This process can be selected and used according to the user's needs; 2. Solvent-based Epoxy Floor Paint Topcoat After 12 to 24 hours of construction, curing to a pedestrian without leaving any traces, it will be coated with epoxy wear-resistant topcoat, which will greatly improve floor finish and durability. 0.12 kg/m2 kaiping aida sanitary ware technology co.,ltd , https://www.kpaidafaucets-jm.com
