What polar activator is better for Organoclay | Organophilic bentonite?

Polar activator Organoclay | Organophilic bentonite,generally, dispersing and gelling are supported by polar activator. Polar activator can form hydrogen bridge bond between organoclay platelets, thereby increasing cross-linking and viscosity.

1.Below listed polar activators are recommended

  • Methanol/water(95/5)
  • Ethanol/water(95/5)
  • Acetone/water(95/5)
  • Glycol ether
  • Propylene carbonate/water(95/5)
  • Propylene carbonate

3.Important note:

  • Suitable dosage of polar activator is very important to dispersion of organoclay and stabilit
  • system. Too much polar activator will reduce swelling once again and viscosity would drop down again. See following chart 1
  • Polar activator should be added only after addition of organoclay, and organoclay has been fully wetted and dispersed
  • For poor wetting resin systems(epoxy, polyester, short-oil alkyd, acrylic resin, etc.) organoclay should be used in combination with surfactant
  • Typical viscosity curve of a system with organoclay. See following chart 2
