Advantages and application prospects of waterborne epoxy resin coatings

Water-based epoxy resin refers to a stable dispersion system in which epoxy resin is dispersed in the form of particles or droplets in a dispersing medium with water as its continuous phase. Because epoxy resin is the thermostat resin of the wire structure, so before construction must be added water-based epoxy curing agent, chemical cross-linking reaction in room temperature environment, epoxy resin curing changed the original soluble and meltable properties and become insoluble space mesh structure, showing excellent performance.
advantages of water-based epoxy coatings:
reasonable choice of epoxy substrates, curing agents and a variety of modifiers and additives, you can prepare different performance of water-based epoxy resin coatings . Many performance characteristics of water-based epoxy coatings determine their wide application prospects compared with solvent-based or solvent-free epoxy coatings. At present, the application of water-based epoxy coating mainly includes the following aspects:
1
floor coating
can be used as a high-performance environment adaptive floor coating instead of solvent-based epoxy coating, can also be used as a polymer component into cement mortar to make high-performance polymer mortar flooring material.
2
wood floor coating
can be used as varnish for wood flooring, replacing the solvent-based polyurethane crystal floor paint currently widely used on the market, with color paint can replace solvent-based epoxy resin and polyurethane magnetic paint, for kitchen, furniture and machinery and equipment.
3
Construction anti-permeability
with the help of water-based epoxy coating excellent mechanical properties and good matching with cement, the preparation of high-strength concrete, in which water-based epoxy coating as an auxiliary component added to concrete or cement mortar, and can improve the impermeability of concrete.
4
Building Bonding Waterproofing
uses epoxy resins for good bonding properties on cement and many organic materials, as well as excellent mechanical and chemical resistance of epoxy resins themselves as concrete adhesives and water-resistant leak-blocking materials.
5
Anticorrosion Treatment and Other Uses
uses the excellent corrosion resistance of epoxy resins as corrosion-resistant coatings for steel and ships, and uses synergies with other general purpose emulsions such as polypropylene emulsions and water-based polyurethanes to obtain coatings with different properties.
