Problems solved by technology

[0002] At present, domestic industrial floor coatings are basically solvent-based and solvent-free epoxy floor coatings and solvent-based epoxy polyurethane floor coatings. Solvent-based varieties will have more organic solvents in the formula, and these organic solvents are used in production. And during the drying stage of construction, a large amount of volatilization into the atmosphere not only pollutes the environment, but also poses a huge hazard to human health; solvent-free epoxy floors generally contain a small amount of reactive diluents, and commonly used reactive diluents have different levels. toxicity, and the overall cost of solvent-free varieties is high, and the requirements for substrates and construction environments are high
