Room temperature crosslinker crosslinked waterborne epoxy resin coating,The first generation of crosslinked waterborne epoxy resin coatings at room temperature
Liquid epoxy resin and pass into a water-soluble amine salt mixed crosslinking agent, the liquid resin for waterborne emulsion form. Shall not apply to the metal objects, its poor corrosion resistance ability, can match to the zero VOC, liquid resin has good workability, rheological property and without cosolvent can achieve good coalescence.
Features: the emulsion stability, uniform; Low solid content, high viscosity when dilute (peak); Short construction period; Viscosity increasing construction period; Not going to happen after gelation start phase separation; Construction period of film formation, high hardness, high; Usually cannot be applied to metal substrate; Slow dry, wet for a long time and poor corrosion resistance.
The second generation of room temperature crosslinking aqueous epoxy coatings
Some solid epoxy resin and modified amine adduct. Long shelf life (6-8 hr), short drying time (4-6 hr), good corrosion resistance; Due to its high molecular weight. So can match, fast dry, long shelf life; Relatively hydrophobic amino crosslinking agent, often need to add a certain amount of solvent to help the coalescence of the emulsion.
The third generation of crosslinked waterborne epoxy resin coatings at room temperature
Based on the high molecular weight, some multifunctional epoxy resin and modified amine adduct crosslinking agent. Through the multifunctional epoxy resin and multifunctional crosslinking agent to improve the crosslink density. Type resin is high molecular weight, dry faster than the second generation and the first generation. Can make low VOC, corrosion resistance can be comparable with the solvent system.
Metal substrate with a coating, primer and enamel of VOC are only 144 ~ 300 g/l. The long-term corrosion resistance, solvent resistance, resistance to friction, good flexibility and for a variety of different substrate adhesion. Often can be used in the cement putty and general substrate used in the paint, primer, paint and industrial maintenance and car repair paint primer and above water ocean.
Waterborne epoxy coatings province resources, low pollution waterborne epoxy coating with water instead of organic solvents. Of waterborne epoxy coatings water sources, can save a lot of resources, in the process of production, transportation, coating, basically no pollutants, no fire danger, thus beneficial to protect the ecological environment.
Chinese name: Diethyl toluene diamine(DETDA)

Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Waterborne epoxy coatings was coated surface after oil removal, rust removal, phosphating treatment, don't have to completely dry coating. In construction of waterborne epoxy coatings when using electrodeposition, objects on the coated surface treatment has more stringent requirements. Construction equipment, tools, can wash with water.
Waterborne epoxy paint electrophoresis coating using the automated construction of electrodeposition method, and the coating efficiency is higher than the spray, brush, spray, construction methods, such as coating quality is stable, less produce evils; Other water-based epoxy coating spray, brush can be used, such as construction method.
Of waterborne epoxy coatings have a large number of hydrophilic group, should focus on improving the corrosion resistance of coating. Waterborne epoxy coatings for room temperature dry waterborne epoxy coating, should take effective measures to guarantee within the prescribed period of time of the water in the release of the film. This is water-based epoxy coating formulation design, production and coating process issue that deserves attention.
Waterborne epoxy resin coatings can be in wet or new pouring concrete surface construction, to have good adhesion to the surface of concrete, concrete can be closed capillary water vapor, and can prevent the whiskering, closed primer for concrete. In a closed primer construction solvent or water-based epoxy floor coating.
Industrial floor coating is an important purpose of waterborne epoxy resin coatings. Waterborne epoxy smell is small, coating surface is easy to clean, especially suitable for hospitals, food factories, supermarkets, dairy and cosmetics factory need to maintain a clean place. If you need a second to decorate, do not affect a painting, new and old coating still maintain good adhesion.
