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
2，Dispersion and activation of organoclay:
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
