Fujitsu has developed a water-based coating that can significantly reduce VOC

[China coating information] Fujitsu has cooperated with Fujitsu Research Institute, a research institution in the group, to develop a water-based coating that can be used for the plastic fuselage of information and communication technology equipment. Compared with the previous solvent based coatings, the newly used oil and volatile organic compounds (VOC) can be greatly reduced. At present, it has been used in the front panel of the fuselage of the two models of the server "sparcm10" series launched in 2013

the water-based coating developed this time adopts a core-shell structure, that is, the core is formed by one resin, and then another resin is used as the shell to wrap it. For example, the pointer deviation from zero after air strike exceeds 0.1% of the maximum impact energy of the corresponding pendulum. By adjusting the volatile state, the fusion between German resin particles and low-temperature drying coating are realized. Oil consumption can be reduced by 54%, and volatile organic compounds can be reduced by 80%. Although solvent based coatings can be used for ICT equipment, the volatile organic compounds contained in the coatings need to be reduced, so Fujitsu carried out this development

to replace the solvent based coating of ICT equipment with water-based coating, there are problems in the coating drying of resin particle fusion and the film performance required for equipment body coating. In order to evaporate water and dry the ordinary water-based coating, the temperature needs to reach more than 100 ℃, but the plastic body of the equipment cannot withstand high temperature and will deform. Moreover, the coating must also have the properties of hardness, adhesion and chemical resistance

the water-based coating developed by Fujitsu and others can fuse resin particles at the drying temperature where the plastic body test can be carried out without human intervention, and obtain the coating performance that can be used for equipment. Ordinary experiment opportunity due to the weight of the sample itself, the measurement results are easy to be inaccurate. By adjusting the volatile state, the low-temperature drying at 65 ℃ can be achieved. At the same time, the structure of using two kinds of resins can promote the fusion between resin particles. This kind of water-based coating can also be used in other servers and laptops, which helps to save resources and reduce the burden on the environment
