translation - Summary

recently, the application of Evonik's coating additive business line requires re tensioning the tensioning wheel; The new technology has developed a vapor phase silica dispersion for water-based coatings. Its main applications include high-performance water-based industrial coatings, automotive coatings and wood coatings, especially suitable for spraying construction and other applications

the challenge in the current application of water-based spraying is to find a special product that combines the advantages of fumed silica (such as excellent sagging resistance, chemical resistance and water resistance) and is easy to use and handle. Of course, it also has very high use efficiency

generally speaking, the viscosity of water-based coatings is much lower than that of solvent based coatings. Therefore, the key technology that requires additional additives is missing; On the other hand, in order to achieve efficient anti sedimentation (and anti sagging during construction) of any component (e.g. pigment) in the coating

our new (fumed silica) dispersion VP disp Wf7620 is developed to meet this market demand. With this dispersion, you can skip the bead grinding process and add it to the recipe without any other high shear equipment. This means that the high rheological effect can be achieved only by adding the dispersion in the mixing process. An important feature of this new dispersion is that it can help achieve high film thickness, and this feature is particularly important for the solid components of waterborne coatings. In addition, this dispersion is very easy to use. As long as you stir it with a mixer, you don't even need a disperser to finish the job

the interviewees are from Evonik's "intelligent surface solutions" R & D center. They are:

sascha herrwerth, Ph.D., who joined Evonik in 2003 and have served different business lines. In 2017, he joined the paint additives business line and led the global R & D Center for "intelligent surface solutions", focusing on the research and development of rheological control additives. Since 2018, he has served as the head of the industrial coating application technology and R & D team of Evonik coating additives business line

Dr. ruediger merstch has been engaged in the coating industry for more than 20 years. He once served as the director of Applied Research in many business departments of Evonik, and later moved to Shanghai to serve as the director of Applied Technology and R & D in the Asia Pacific region. In 2019, he became the director of Evonik's "intelligent surface solutions" R & D center and led the automotive coating application technology and R & D team

this new dispersion introduced by the two experts will be officially displayed at the 2019 China International Coatings exhibition in Shanghai this year. We are looking forward to giving you further introduction at the Evonik booth
