MT 6900-30X Rheological Additive
Applies to solvent system ,high cost performance,anti- sagging organic rheological additive
   MT 6900-30X is a modified paste polyamide thixotropic additive. In the paint, printing ink and coating to form a strong network structure, with excellent thixotropic property and good dispersion, providing excellent anti-sagging, anti-settling, thickening effect.
  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
3、Typical Physical Data

4、Properties And Applications
  1、Easy-to- disperse, can be incorporated into coatings system by simply mixing.No coarse-grained, grain-free, with excellent stability.
  2、 To improve the system’s stability, and thixotropic properties, suitable the anti-setting of glass powder, aluminum paste, pearl powder
  3、Help aluminum powder, pearl powder flake to orient and enhance the flash effect
  4、Good compatibility with resin, does not affect the glossy, and can increase of the hardness of paint film
  5、Wonderful to the touch, good transparency, and have no effect to the leveling of heavy coating
  6、Need’t heat treatment to activation, can use in a wide range of temperature(25℃-70℃)
5、Levels Of Use And Incorpotation
  Levels of use: 1.0-4.0% total system weight
  Incorpotation: The general xylene, toluene and butyl acetate solvent systems, such as paint ,are applied, but some low-yuan alcohol will dissolve MT 6900-30X inside part of the modified polyamide compounds.In high-speed dispersion when the temperature is optimally controlled at 60 ℃ below the speed of 1000-2000 r / min, mixing time is less than 30 minutes.Thixotropy will reduce ,due to high shear stress and long time dispersion. In high-shear dispersion machine for grinding, the mixing time should be shortened accordingly. 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 6900-30X,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 added to the finished paint.
  Steps:① Put 50% of MT 6900-30X, resin and solvent into reactor
     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
6、Compatible Brand
  MT 6900-30X is fully compatible with the following brands :
  Deuchem 229 solvent thickening, anti-setting agents
