Marketing: floor coating competition for waterborne epoxy floor

It is suggested that the most widely used waterborne epoxy coating is water dispersive epoxy coating The epoxy resin is not water-soluble but can be emulsified in water It consists of two components: the base material is hydrophobic epoxy resin, and the curing agent is hydrophilic amine curing agent Bisphenol a type is widely used in epoxy resin, while bisphenol F type epoxy resin and epoxy linear phenolic resin are rarely used Water soluble epoxy usually has good adhesion to most surfaces, and can be used for steel, concrete and aluminum substrate surfaces The film formation of waterborne epoxy coating is more strict than solvent epoxy because there are two steps in the process: water evaporation and film polymerization Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: at present, the widely used waterborne epoxy coating is mainly water-soluble epoxy coating The epoxy resin is not water-soluble but can be emulsified in water It is composed of two components: the base material is hydrophobic epoxy resin, and the curing agent is hydrophilic amine curing agent Bisphenol a type is widely used in epoxy resin, while bisphenol F type epoxy resin and epoxy linear phenolic resin are rarely used Water soluble epoxy usually has good adhesion to most surfaces, and can be used for steel, concrete and aluminum substrate surfaces The film formation of waterborne epoxy coating is more strict than solvent epoxy because there are two steps in the process: water evaporation and film polymerization and crosslinking If the curing rate is lower than the evaporation rate of water, the paint film will contain water, and the performance will be reduced This makes the control of temperature, relative temperature and ventilation more important than solvent epoxy During construction, the relative humidity shall not exceed 85%, preferably below 65% Excessive relative humidity will delay the evaporation of water In the process of water evaporation, epoxy resin and curing agent are crosslinked When the evaporation rate of water is faster than that of curing agent, there is no water in the paint film If the evaporation rate is less than the curing rate, there will be water in the paint film, which will affect the performance of the paint film The mixed service life of waterborne epoxy coating is shorter than that of general solvent epoxy coating, generally about 2 hours Note that unlike solvent based epoxy coating, water-based epoxy coating can not be distinguished by viscosity rise After 2-3 hours, water-based epoxy coating seems to be able to be used, but it can not be used in practice, because its protective performance has been greatly reduced The mixing life is not represented by the increase of viscosity At 20 ℃, the mixture after 3 hours seems to be still available, but the protective performance of the coating has been greatly affected, so it can not be reused It must be noted that the mixing life will also be reduced when the temperature is reduced, but not when the temperature is reduced, the mixing life will be extended The recoating performance is better than that of solvent based epoxy coating, which can be recoated after a long time and still has good adhesion In essence, they are all composed of base material, pigments and fillers, auxiliaries, solvents, etc among them, the base material is cured by two-component crosslinking of epoxy resin and curing agent The difference is that the oil uses toluene, xylene, acetone, etc as solvent, the water as solvent, environmental protection, safety and cost saving; the oil is molecular crosslinking, and the water is particle crosslinking; Therefore, the oil-based crosslinking degree is high, the luster is high, the density is tight, and the water-based epoxy is opposite The most important way to improve the performance of waterborne epoxy is to reduce the particle size and improve the stability of the product The performance of water-based epoxy is constantly improving The performance of Hanzhong water-based epoxy h228 is close to that of oil, with a gloss of more than 90 The pursuit of high quality is the driving force for the rapid growth of coating enterprises The owners of coating enterprises keep their knowledge and similar information The mode that coating enterprises can learn from -- Sam's membership store mode After sales service of coating is maximized, and consumers are deeply in love with each other How can small and medium-sized coating enterprises make use of the Spring Festival holiday to consume? O2o or coating e-commerce is another pit Paint industry integrates into the development of the Internet to promote the prosperity of the industry Paint marketing: not all paint products are suitable for holiday marketing Experiential marketing mode ------ you price it Micro marketing opens the era of precision marketing Paint enterprise culture, focusing on thinking The eight strategies for online marketing of paint enterprises are paint home, which focuses on paint, diatom mud and paint paint, Coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fire retardant coating,
