    It is pointed out that UV curable water-based coating combines the advantages of water-based coating and UV curable coating, which has developed rapidly in recent years, and is also one of the main development directions of UV curable coating in the future The advantages of UV curable waterborne coatings are: oligomers with high molecular weight can be used to improve the adhesion to some substrates and other physical properties of the cured film, unlike oligomers with traditional UV coating, whose relative molecular weight is limited by the construction viscosity: the viscosity of the system can be adjusted by water instead of diluting the monomer, so that the activity can be avoided Shrinkage caused by diluting monomer; Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings: UV curable water-based coating combines the advantages of water-based coating and UV curable coating, which has developed rapidly in recent years, and is also one of the main development directions of UV curable coating in the future The advantages of UV curable waterborne coatings are: oligomers with high molecular weight can be used to improve the adhesion to some substrates and other physical properties of the cured film, unlike oligomers with traditional UV coating, whose relative molecular weight is limited by the construction viscosity: the viscosity of the system can be adjusted by water instead of diluting the monomer, so that the activity can be avoided Shrinkage caused by diluting monomer; extremely thin coating can be obtained by this method, and the equipment is easy to clean; after drying with water, the dry coating can be obtained before irradiation, so it can be used for surface curing of three-dimensional objects, the dry coating before irradiation can reduce the adsorption of dust, and the defects of coating can be repaired before curing The disadvantages of this technology are: dehydration and drying before curing, low gloss, poor solvent resistance and scratch resistance In fact, the "water-based" system is not suitable for all fields, and the "water-based" system is not really harmless to the environment, because when cleaning the water-based ink or coating, it can be dissolved or dispersed in water, which is difficult to remove, and the compounds, such as acrylic acid, are very harmful to fish and other aquatic organisms UV curable water-based coating is conducive to environmental protection, and has the characteristics of rapid curing rate, in line with the requirements of the development of the times In developed countries such as Europe and America, Hoechst, UCB, ICI, Zeneca, BASF and other companies have launched their UV curable waterborne coating products At present, the shortcomings of the technology mainly include: the long-term stability of the paint moisture dispersion system needs to be improved, there are not many kinds of photoinitiators available, most of them use the traditional photoinitiators, for the pigment coloring paint, there is less choice, and the addition of drying and water removal device has a negative impact on the promotion and application of the technology Therefore, it is still an urgent task to develop the technology of Waterborne UV curable coatings to continue to carry out basic research, develop strengths and suppress weaknesses, and vigorously expand its application fields A kind of polyurethane water-based coating with special properties has been developed by foreign scientists with cation electrodeposition method This method can greatly shorten the evaporation time of water in the coating, and solve the problem of long time consumption in the whole production process of water-based coating 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,
