Gellants Paints (Hectone – 40, 50, FD -1, FD-2 for Paints & Printing Inks)

General Chemical & physical Properties of Hectone Gellants - Paints

The Heclone (Organoclay) products are finely divided, light creamy / brown coloured powder. Heclone have very low chemical reactivity and are readily stored and handled without difficulty. They are non-hygroscopic and do not loose effectiveness with storage.

Chemical Properties:

Hectone Gellants are chemically neutral and their presence does not affect the pH of any organic liquid, The Hectare Gellants are resistant to the action of acids & alkalis in the working range of pH 4 to 10 and maintain gel stability over extended storage periods in this range. However, prolonged contact at lower or higher pH may cause decomposition of the Heclone Gellants with consequent reduction of gel strength.

Physical Properties :

Within the pH range 4 to 10, the Heclone Gellants are insoluble in all aqueous or organic liquids. A properly gelled Heclone compound, however, consists of particles in the micron range, so that a colloidal range is obtained in which no particles are discernible.

The equilibrium moisture content of the Heclone products are about 3 % by weight and this amount of water is necessary for optimum gelling properties. Removal of this water distracts seriously from gelling efficiency.

Once an Heclone compound has been gelled, it is stable in service up to moderately high temperatures short exposures to temperatures as high as 325° F has no effect.

The dry Heclone particle is resistant to wetting by water, because of the layer of long hydrocarbon chains around each individual unit.

Toxicological Properties :
Normal precautions should be taken to prevent breathing the finely divided powder, as would be taken for any other inert materials. Studies undertaken seem to indicate that a comparably low order of toxicity should be expected.

Hecton/Gel -on gellants Incorporation Techniques - Paints

diecfone /Gel on gellants are supplied in the form of dry powders. In order to develop their useful properties, these gellants must be thoroughly dispersed, so as to get complete separation of the minute ultimate particles. This dispersion is readily obtained by applying a combination of the following two forms of energy.

  1. Mechanical shear action, such as grinding milling stirring.

  2. Chemical energy, by the use of a properly chosen polar additive, to initiate the separation of the minute ultimate particles.

The ease with which a good diecfone I Gel - on dispersion can be obtained is determined initially by the nature of Organic Liquid used. Such factors as the polarity of the liquid and its inherent viscosity have an important influence upon the ready wetting of the diecfone I Gel - on particle and consequently upon the efficiency of the grind. For example, these are considerable difference between ordinary mineral oil and boiled linseed oil, with respect to the total energy required in milling to form a folly gelled diecfone I Gel - on paste.

As a general rule, a diecfone I Gel - on gelling agent should be dispersed in the same manner as a relatively easygrinding pigment.


To form the gel, weigh about 10% diecfone /Gel -on. Select appropriate non-polar vehicle (90%) and place it under stirrer or in milling machine. Stir gently. Add gellant to vehicle slowly and then apply high shear for a couple of minutes. To aid dispersion, add 30-50% (this weight based on the gellant weight) Methanol (95/5). On addition of polar dispersant, the mass thickens to a gel. Continue milling or stirring for a few minutes to obtained thick, creamy, smooth gel. This gel can be incorporated in the dispersed paint system.

(Note: - the sample supplied is suitable for non-polar or medium polar organic solvents.)
