6900-20X anti-anti-sag agent Shen 

 6900-20X is fully expanded the special modification of organic compounds in the dispersion process does not require heating and grinding. 6900-20X for a variety of solvent-based paints, coatings can increase the viscosity and thixotropy, with excellent anti-settling properties of powder and anti-sag resistance. In addition to matte, metallic paint, but on the glass powder, silica powder, barium sulfate, transparent powder powder Shen Yi also has a special performance. 6900-20X in the anti-sag and leveling to do a better balance between, do not need the same with several anti-settling agent to the anti-sag, leveling and good enough, can be used alone 6900-20X. 
 Specifications: 
 Appearance: white or light yellow cream body 
 Active ingredient: 20% 
 Acid Value: ≤ 2.0 (/ g) 
 Scope: 
 This product is suitable for a variety of solvent-based coatings, such as PU coating, oil modified alkyd resin coatings, amino resin coatings, chlorinated rubber paint, epoxy paint, acrylic paint, unsaturated resin coatings. 
 Usage: 
 By adding the specific amount of resin, pigment type, the use of solvents and the desired finished effect and processing methods are different. In general, the basic amount of about 1-3% of the total coating. 
 Usage: 
 * General xylene, toluene and butyl acetate solvent system coating are applicable, but some low alcohols will dissolve part of 6900-20X in the polyamide wax. 
 * High-speed dispersion, the temperature is best controlled at below 60 ℃, speed 1000 ~ 2000 r / min, mixing time of less than 30 minutes. 
 * Thixotropy due to high shear stress and reduced time dispersion, therefore, in the high shear dispersing machine grinding, the mixing time should be shortened 
 * The best way is: in a certain shear force and a short time, the first made of pre-dispersed slurry,

 Steps: 
 1) all the materials put into the tank. 
 2) 1000 ~ 1500 r / min speed of 2 to 3 minutes pre-dispersed to a uniform state. 
 3) and then from 2000 to 3000 r / min rate of spread of 10 to 30 minutes, the temperature was controlled at below 40 ℃. In order to avoid accumulation of air in the slurry, mixing blade should be appropriate to move up and down.
