    It is suggested that anti settling agent plays an important role in modern coatings and has an important influence on the production, storage, coating and coating performance of coatings Therefore, its use has been paid more and more attention and new varieties with better performance have been developed At present, the varieties of anti settling agents are quite complete   1 Organic Modified Bentonite In terms of coating, organobentonites are generally used as anti settling agent and thickener The mechanism of preventing precipitation is to change the rheological properties of the system, make it thixotropic, so as to prevent the settlement of pigments and fillers At present, organobentonites are widely used Add it to chlorosulfonylethylene anticorrosive coating, chlorine Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings: anti settling agent plays an important role in modern coatings, which has an important impact on the production, storage, coating and coating performance of coatings Therefore, its use is increasingly valued, and new varieties with better performance are constantly developed At present, the varieties of anti settling agents are quite complete In terms of coating, organobentonite is generally used as anti settling agent and thickener The mechanism of preventing precipitation is to change the rheological properties of the system, make it thixotropic, and prevent the deposition of pigments and fillers At present, organobentonites are widely used It can make the coating smooth without sagging and prolong the settling time of the pigment Adding organobentonite to copper epoxy conductive coating can solve the problem of copper powder deposition, improve the conductivity of the coating surface, and the minimum surface resistivity of the coating can reach 6.0 × 10-3 Organobentonites as thixotropic agents can significantly improve the thixotropy of copper based conductive coatings The application of organic modified bentonite as anti settling agent in the coating can significantly improve the performance of the coating, but due to the deep color, poor transparency, easy to produce brush marks, increasing the amount of solvent, and difficult to guarantee the solid content of the paint liquid, there are certain limitations in the application 2 castor oil derivative Castor oil derivative is a very valuable rheological additive for thick coating It is widely used in various coatings to endow thixotropic structure, improve the suspension of pigment, control the flow hanging without sacrificing the flow and leveling, control the permeability to porous objects, generally do not react with other components in the coating, do not affect its water resistance in organic system, and do not affect the durability of the coating Good effect, no yellowing in the film, and give storage stability 3 fumed silica fumed silica is an ideal anti settling agent, which is very effective to prevent pigment precipitation in paint system The precipitation effect of fumed silica is very beneficial to the storage of coatings The use of fumed silica can ensure its dispersion without precipitation In order to improve the dispersing quality, the high-speed dispersing machine or three roller machine is usually used If the dispersing is not enough, the film has particles, which affects the glossiness 4 polyolefin particle polyolefin particle can be used as the rheological assistant of coating, which has the function of anti sinking and anti sagging, especially to prevent baking sagging Polyolefin particles provide excellent pigment suspension without obvious thickening When diluting to spraying viscosity, they make pigment suspend in the system, improve leveling, prevent agglomeration in immersion tank, painting tank and storage container, and help prevent drawing phenomenon sometimes occurring in spraying In baking, it can prevent sagging, strengthen pigment wetting, help to keep viscosity stability in storage, and control metal sheet orientation and improve impact performance in flash paint Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
