Core tip: waterborne epoxy resin coating is an emulsion coating Its film forming mechanism is quite different from that of general polymer emulsion coatings, such as acrylic emulsion, and is also not identical with that of solvent based epoxy resin coatings The curing film formation of general polymer emulsion coatings is a physical process The glass transition temperature of dispersed phase particles is relatively low When water evaporates, a compact structure is formed, and the film is condensed under capillary pressure In solvent based epoxy coating system, both epoxy resin and curing agent are dissolved in organic solvent in molecular form, forming a homogeneous system Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coatings home news: waterborne epoxy resin coating is an emulsion coating Its film forming mechanism is quite different from that of general polymer emulsion coatings, such as acrylic emulsion, and is also not identical with that of solvent based epoxy resin coatings The curing film formation of general polymer emulsion coatings is a physical process The glass transition temperature of dispersed phase particles is relatively low When water evaporates, a compact structure is formed, and the film is condensed under capillary pressure In solvent based epoxy coating system, epoxy resin and curing agent are dissolved in organic solvent in molecular form, the system formed is homogeneous, and curing reaction is carried out between molecules, so the curing reaction is relatively complete, and the film formed is also homogeneous Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
