Water-based Bentonite Rheological Additive For Paint And Coating

YH-D WATER-BASED BENTONITE RHEOLOGICAL ADDITIVEProduct features:YH-D water-based bentonite rheological additive is a purification of modified montmorillonite clay.It is a kind of highly-efficient wanter-based inorganic gel.It is widely used in thickening,suspension and rheology-control of water-based coating.YH-D is a clay with feature of grey white,toxic tasteless,soft texture,wide PH range etc.It is Highly-mobile powder. It is good thickener,emulsion stabilizer,rheological additive of water-based system.Its gel is similar with the American Vander Bill Ltd's Veegum or Magnabrite gel product.It is widely applied in water-based systempaint,middle to high grade emlsion paint,nano-meter industies and so on.Use Method(1)pre-gel method:The YH series bentonite(inorganic gel) rheological additive could be usd as pre-gel:the preparation of a pre-gel concentration should be according to the desired viscosity level of the stirring speed and the product of the dispersing device in order to obtain the best results.Generally speaking,2-10%(mass percentage of the whole system)/Weigh a certain amount of the product under stirring slowly added to water of 25-30°c note aviod caking.After the addition,adjust the speed to 1000-1200RPM,and disperse it by stirring for 30 minutes,so that products can sufficiently disperse into the water and form a unform gel,stand it for 8-24 hours,and use it after the colloidal plays stabilized thckening effect.(2)Dry powder methodYH series bentonite rheological additives(inorganic gel)can be directly put into required system and dry powder.Formulated cincentration of the system should be decided according to the needs of the various indicators of the stirring speed and the dispersing device(viscosity level,thixotropy,ect.)Advantage：☆ Good thickening and thixotropy property.☆ Good swelling property.☆ Good transparency.☆ Economical in price.
