2019-12-05Precipitated silica: Also known as hydrated silica, activated silica, precipitated silica, and precipitated hydrated silica. English name: Silica CAS RN: 14464-46-1 Molecular formula: SiO2 * ......
2019-12-05For example: Organic Electroluminescent Device (OELD) is a new type of flat display device newly developed, but the service life of OELD device can not meet the application requirements. One of the te......
2019-12-04Because many shoppers like to scratch the paint film with their nails or keys when they judge the paint is good or bad, to see if there are any scratches? Therefore, waterborne wood paint must have hi......
2019-12-04The final step in the production of water-based wood lacquers is viscosity adjustment. The viscosity term is called rheological properties. Good waterborne wood lacquer must have good leveling and goo......
2019-12-04Drying speed is a key factor in the construction of water-based wood paint factories. Because the operation of the factory is more compact, and the paint can't wait that long after painting, the dryin......
2019-12-04The adjustment of the abrasiveness of water-based wood lacquers is very important for the entire workability. Just like transparent putty and transparent primer, good sandability is even more necessar......
2019-12-04When matting agents are used, it is necessary to measure the fineness or Hegmann value of the coating to obtain information on the degree of dispersion. Furthermore, we can control the gloss in the 60......
2019-12-03By studying matting agents, we can divide them into two types: (i) stirring and mixing with coatings, and (ii) dispersing with pigments and fillers. The second process is easy to implement. By using a......
2019-12-03There are many ways to obtain matting agents from silica, which can be divided into two categories according to their manufacturing processes. One is the gel method, and the other is the precipitation......
2019-12-03Pumice powder was used to sand the outer surface of dry paint films. Through processing to obtain fine scratches, the paint film has a fine and noble matte appearance. More materials are now used to m......
2019-12-03What is the "matting effect"? For example, color, whether it is matte or shiny, is a subjective impression formed by our senses. Light is reflected from a flat surface into our eyes, and we classify i......
2019-12-03Matting effects are everywhere in everyday life: they can be found at home, on the way to work, or in restaurants at night. Most of the interior furniture uses a matte surface, and the wooden panels c......
2019-12-03Because of its use, coatings often need to add some fillers, and the particle size, particle size distribution, volume concentration, and dispersibility in the coating system will greatly affect the g......
2019-12-02The surface gloss of an object is closely related to the roughness of the object surface [1-2]. When light strikes the surface of an object, part of the light will be absorbed, part of it will be refl......
