Holland, Japan, Spain and other recent foreign paint patent express

1. Akzo Nobel of the Netherlands launched a coating method for the exterior surface of artificial underwater engineering facilities (international patent application no. WO2017064016). The patent covers surfaces at least partially submerged in water, such as ships or offshore platforms. The coating process is based on the selection technology of coating based on computer software. To evaluate and select the coating based on the minimum tolerability of the coating associated with the total roughness. The patent also relates to the specific application method of the coating software.

2. Fuji xerox corporation of Japan launched a powder coating and electrostatic powder spraying process (us patent no. : US20170087589). The powder coating contains thermosetting resin and thermosetting auxiliaries. The powder coating is applied to the surface of the coated workpiece by electrostatic spraying, and then heated to solidify to form a coating film. Where, the average powder volume particle size of the coating after electrostatic spraying and the average powder volume particle size before spraying should meet the following conditions:

3. The university of alicante, Spain has introduced a hybrid nano pigment synthesis process and optimization method (international patent no. WO2017072382). This patent involves the synthesis process of the nanometer pigment, in which at least two of the following compounds are used: surfactant, mordant, coupling agent, nanometer clay, resin, etc. The patent also covers the application of the nanometer pigments, such as ceramics, ink, coatings, synthetic or natural fibers, fabric materials, paper, polymer materials, cement, mortar, cosmetics, etc.

4. An American company introduced a hydrophobic modified carbamate thickener and its preparation method (European patent application number: EP3165547). This patent relates to a water-soluble or water-dispersible associative thickener, whose logP value of hydrophobic chain segment is 2.9-8.2, and whose average relative molecular mass is 48,000 ~150000. The associative thickener contains polyether, polyalkyl oxide, polymethylacrylamide, polysaccharides or polyvinyl alcohol backbone chains. In addition, the patent relates to a hydrophobic modified hydrocarbon oxide polymer (carbamate ester-urea-carbamate) thickener containing the following structural units :(a) water-soluble polyalkanediol; (b) c4-20 aliphatic diisocyanate; (c) hydrophobic end sealant or hydrophobic bifunctional agent.

5. According to France international group, a anti-fogging coating and its application in optical components (French patent no. : FR3042500) This patent relates to an organosilane compound having at least one organosilicon atom, with at least one hydrolyzable, at least one hydrophilic, at least one hydrophilic and at least one hydrophobic hydrophobic group in its molecular structure (including fluorine atoms). The hydrophilic and hydrophobic groups above are bonded with the same organosilicon atom. The patent also relates to an optical element, such as an eyeglass, whose surface is coated with an antifogging coating made from the above compound. The coating has good anti-fogging performance, and surfactant can be used in the coating process according to the specific performance requirements.
