3、Properties And Applications
   1、 Easy-to- disperse, can be incorporated into coatings system by simply mixing;
   2、 To improve the system’s stability, and thixotropic properties, suitable the anti-setting of glass powder, aluminum paste, pearl powder,and help aluminum powder, pearl powder flake to orient and enhance the flash effect; 
   3、 Good compatibility with resin, does not affect the glossy, and can increase of the hardness of paint film;
   4、 Need’t heat treatment to activation, can use in a wide range of temperature(25℃-60℃)
  Applies to most of solvent-based or non-aqueous coating ,paint ink systems, such as toluene, xylene, butyl acetate, ethylene glycol butyl ether, ethanol, etc.It is mainly used in the following resin-based material of the primer, filler, and aluminum powder, pearl powder top coat
alkyd resin acrylic resin polyurethane asphalt/ epoxy
tar / asphalt chlorinated Rubber Epoxy resin unsaturated polyester
thermosetting melamine resin epoxy / polyamide resin acrylic / polyurethane
5、Levels Of Use And Incorporation
  Levels of use: 1.0-5.0% total system weight ( Detailed technical information, please request to our sales staff) 
  Incorporation: In high-speed dispersion, the temperature is optimally controlled at below 60 ℃, stirring time of less than 30 minutes.
  The best way is: make pre-dispersed slurry then disperse the MT 6900-20X with limited shear in a short period of time.
   1 Direct incorporation: Add resins, solvents and MT 6900-20X,pre-mix directly, high-speed disperse 5 minutes, the temperature at 30 ℃ -60 ℃, and then add the other components.
   2 Master batch preparation: A master batch may be prepared by dispersing the paste in a vehicle and/or solvent which can be addedto the finished paint.
   Master batch formula: 6900-20X(20%) solvent(40%) resin(40%)
   Master batch process:
   1)Put the above materials into vehicle
   2)Pre-mixing at speed of 1000-1500 r / min until for 2-3min until uniformly
   3)Then mixing 15-30 minutes at speed of 2000-3000 r / min, temperature at below 60 ℃. In order to avoid the accumulation of air in the slurry , mixing blades should be moved up and down.
六、Compatible Brand
