The MMT technology provides performance benefits which are not possible with traditional organoclay additives. Traditional organoclays are very hard to disperse, typically requiring both very high shear mixing and a polar activator to help delaminate the aggregates of clay platelets. Due to the multiple particle morphologies of this product, the powder disperses very easily into oils or solvents with only moderate shear. GARAMITE® 7303 exhibits a very unique rheology profile compared to other thickening additives. Very high low-shear viscosity can be achieved by incorporating this product into formulations which results in outstanding ant-settling and anti-syneresis properties.

With the aid of the pigments and fillers, the additive generates a three-dimensional network structure. The entanglement of the high molecular weight polymers is responsible for the development of the pseudoplastic flow behavior. The polarity of the system and the incorporation temperature influence the rheological effectiveness. The settling of the pigments and fillers is prevented and outstanding anti-sagging properties are produced due to the rapid rebound in viscosity after shearing. The additive has no "false body effect", no negative influence on the intercoat adhesion, and it is easy to process on account of its liquid form. view less

It significantly increases the viscosity in the low shear range. It reduces sagging and increases storage stability. The additive is liquid and therefore easy to handle. It is not necessary to adjust the pH value or control the temperature during incorporation. When combined with rheology additives which are effective in the high shear range, such as the RHEOBYK-L/T series, it enables an optimum processability. view less
