Silicone rubber has a variety of excellent properties, but its mechanical properties such as compressive strength and tear strength are poor and cannot meet the requirements of the process. It is nece......
2019-12-13MQ silicone resin is usually prepared by sol-gel method. The main raw material of M chain is hexamethyldisiloxane (MM) or trimethyl monochlorosilane. The raw material of Q chain is mainly water glass ......
2019-12-13MQ silicone resin is a relatively unique structure of silicone resin. It consists of an organosilicon compound containing a tetrafunctional siloxane link (SiO4 / 2, Q) and a monofunctional siloxane li......
2019-12-13Inorganic thickeners have the advantages of strong thickening, good thixotropy, wide range of pH value adaptation, and good stability. However, since bentonite is an inorganic powder, it has good ligh......
2019-12-12The associative polyurethane thickener is an associative structure that is damaged under the action of shearing force and the viscosity is reduced. When the shearing force disappears, the viscosity ca......
2019-12-12Polyacrylic thickeners have strong thickening and good leveling properties, good biological stability, but sensitive to pH and poor water resistance.......
2019-12-12Cellulose thickeners have high thickening efficiency, especially for thickening the aqueous phase; there are fewer restrictions on coating formulations, and they are widely used; a wide range of pH ca......
2019-12-12At present, there are many types of thickeners that can be used on the market, mainly including inorganic thickeners, celluloses, polyacrylates and associative polyurethane thickeners. Inorganic th......
2019-12-12Powder coating curing reactions can be divided into two types, one is the direct reaction without small molecule release type, such as the reaction of carboxyl groups with epoxy groups, and hydroxyl g......
2019-12-03(A) Benzoin easily decomposes under heating and causes yellowing of the coating film. Too much benzoin will cause discoloration of light-colored powder coatings. (B) As the thickness of the coating......
2019-12-03The powder coating is deposited on the workpiece in a loose structure after spraying. This loose structure causes a large amount of voids between the powder particles and the powder particles to be fi......
2019-12-03The essence of the Bernard vortex is the change in surface tension caused by the viscosity change during the melt-solidification of the powder coating, which causes the fluid with high viscosity and l......
2019-12-03The formation of pinholes in powder coating films is closely related to its unique melt-solidification process. Therefore, to study the formation mechanism of pinholes in powder coating films, the mel......
2019-12-03Pinholes, as a type of coating defect, are particularly noticeable in high-gloss powder coatings, and low-gloss powder coatings, especially matte sand-patterned powder coatings, are usually not notice......
2019-12-03Powder coatings and water-based coatings, light-curing coatings, and high-solids coatings are known as the four new environmentally friendly coatings. As an important branch of coatings, powder coatin......
