Organoclay is a chemically modified type of clay that is used for Rheological additives and other solvent system. It consists of bentonite, which is a clay formed from volcanic ash that contains the mineral montmorillonite. Organoclay also contains artificially added chemical compounds known as quaternary amines, which give the clay its useful industrial properties. By exchanging the original interlayer cations for organocations (typically quaternary alkyl ammonium ions) an organophilic surface is generated, consisting of covalently linked organic moieties. The lamellar structure remains analogous to the parent phyllosilicate. Organoclay can be used to remove oil from water, as a component in paint formulations or as a viscosifier for oil-based drilling fluids. It can be used in polymer chemistry as a nucleating agent. It decreases cell-size but may have a decrease in closed cell content due to uneven dispersion. The addition of quaternary amines allows the clay to chemically dissolve substances such as oil and grease, removing them from water.
Organoclay are superior and established import substitute rheological additives, gellants and thickeners equivalent to internationally renowned organoclays for all solvent borne systems, organic liquids and oils where thickening, gelling, anti setting, anti sagging, body, tack and viscosity controlling characteristics are desired.
Different Organoclay range performs effectively across the aliphatic and aliphatic/aromatic blend of solvents, including low, low - medium, medium - high polarity range with activation as in conventional organoclays and without activation for super and easy dispersion as in 2nd generation organoclays. Incorporation is simplified to yield consistency and uniformity in major formulations with simple mechanical action (milling / shearing / grinding) and with or without chemical activation (polar solvent) as desired.
