organoclays
1.General Information
organoclays are manufactured by modifying bentonite with quaternary amines, a type of surfactant that contains a nitrogen ion, the nitrogen end of the quaternary amine, the hydrophilic changed, and ion exchange onto the clay platelet for sodium or calcium.
2.physical propertiesÂÂ
The amines used are fo the long chain type with 12-18 carbon atons. After some 30 per cent of the clay surface is coated with these amines it becomes hydrophobic and, with certain amines, organophilic.
