Epoxy-based coatings show the advantages of new coating technology

the world's coating technology from the process to the design type, in this with the new characteristics of industrial technology in the 21st century, the performance of excellent, environmentally friendly green epoxy-based coatingwill will become an important rolethe development of coating technology is in the process of transformation, from the development of coating technology as early as the early 1960s, with the United States on the control of VOC emissions of air cleaning law (66 regulations) promulgated, and since then many countries in Europe and the United States environmental protection bureaus enforcement of similar regulations, prompting the reduction of VOC has been placed on the main agenda of paint manufacturers in these countries, the result of this promotion of the development of four replacement technologies, namely, industrial solvent-based high solid coatings, water, powder and radiation curing coatingsRadiation-curing coatings have been used on laboratory scale since the early 1970s, but their actual commercialization comes rather late because of insufficient attention to the development of suitable UV curing channelsThe fast-cured, solvent-free epoxy coating, also based on bpa A epoxy, was known in the 1960s, but the commercialization of this technology was greatly delayed by the lack of suitable construction equipmentTherefore, it is very important to speed up the process of commercialization of technology in the future, and to properly balance the focus of all aspects of technologyorganic-inorganic hybridization is an important part of the new technology of coatings, the current organic-inorganic hybridtechnology and the development of paint varieties are: a new generation of gas-dry carbon- sixixane hybrids, such as epoxy polysilane, sixixane-acrylic acid, silicone latex, etc, have outstanding durability, and has been commoditizedAccording to experts from China Epoxy Resin Industry Association, one of the most prestigious when pushing engineering epoxy polysiloxane coatings, used in heavy corrosion-resistant coating systems, different from organic/ inorganic zinc-rich coatings, epoxy intermediate layer and polyurethane paint 3 system, but organic/ inorganic zinc-rich primer and epoxy polysiroxane paint 2 system, performance is better than the former low VOC, reduced Pollution of the environment, and the emulsion system developed by hybrid technology is made by the kernel shell emulsification and external emulsification method, the raw material is made of acrylic and alkyl acid, this gas-drying water hybrid emulsion has the dual advantages of acrylic emulsion and alkyl emulsion, can be used in the construction field, has excellent performance, such as gloss, flow and leveling, brushability, wetting, etcsilicone emulsion is also a hybrid emulsion, which combines ethylene-based siloxane or its derivatives with acrylic monomers for penetration of concrete/brick closed primers and silicate coatings, which can be mixed with acrylic emulsions to create long-life silicate coatings with long-life silicate coatings, which have 8 years of durability, excellent resistance to staining, wind and rain without sacrificial breathingMixing water-repellent polysiloxane composition into latex paint for the exterior walls of buildings has an excellent water drop effectEpoxy polysiloxane coating has excellent stain resistance, can be used as a self-polishing coating without orgin, and has a dominant position in the non-toxic anti-fouling paint market
