Water-Based Epoxy Resin is a stable dispersion system prepared by dispersing epoxy resin in the form of particles or droplets in a dispersion medium with water as the continuous phase. As epoxy resin is a thermosetting resin with linear structure, waterborne epoxy curing agent must be added before construction. Chemical crosslinking reaction occurs at room temperature. After curing, the epoxy resin changes its original soluble and fusible properties into an insoluble and fusible spatial network structure, showing excellent performance.
Advantages of waterborne epoxy resin coating:
1. Strong adaptability, high adhesion to many substrates, excellent corrosion resistance and chemical resistance of cured film, small shrinkage, high hardness, good abrasion resistance, excellent electrical insulation, etc.
2. Good environmental protection performance, no organic solvent or low content of volatile organic compounds, which will not cause air pollution, thus meeting the current environmental protection requirements.
3. It is truly water-based. With water as the dispersion medium, it is cheap, odorless and incombustible, and the safety during storage, transportation and use is greatly improved.
4. Good operability. The waterborne epoxy resin coating has good construction performance. The construction tools can be directly cleaned with water. They can be cured at room temperature and in a humid environment. There is a reasonable curing time and a high cross-linking density can be guaranteed. This is incomparable with ordinary waterborne acrylic coatings and waterborne polyurethane coatings.
