Organoclay (Bentone SD-1) is is an organic derivative of bentonite clay and used as a rheological additive. Mixes easily with oil and alkyd paints to increase viscosity, prevent pigment settling, and increase crispness of handling. Add 1�4% of total weight of the paint.
It provides viscosity increase, reduces sagging of coatings on vertical surfaces and prevents settling of pigments and fillers.
How to Use Organoclay is readily dispersible for non-polar to medium-polarity organic applications. It may be added at any point in the paint making process is using all normal paint-making equipment. This rheological additive can be incorporated in the pigment grind under high shear and under low shear. A chemical activator is not required to disperse the organoclay in conventional solvent containing paints.
It can be added to the pigment grind or by mixing rather than grinding. Its does, however, require some minimal shear (minimum tip speed 4 meters per second when a high speed mixer is used). The liquid paint to which it is to be added should well stirred as it is sifted in. Sufficient time for full activation should be allowed. The amount of time required will depend upon the amount of paint, the type and speed of mixer in use and the viscosity and solids of the system. When grinding with the pigment, it is not sensitive to high temperatures and no minimum temperature is required.

Natural Pigments is a limited liability company based in Willits, California. We manufacture and distribute rare and hard-to-find materials for fine artists and decorators. We specialize in supplying artists' materials that were used in historical painting since pre-historic times up to and including the nineteenth century.
We constantly search for materials and products of the finest quality so that we can bring them direct to you from the source. To do so, we travel the world to find materials specifically for use by professional artists and decorators. We obtain minerals from mines in Afghanistan, Chile, Russia, Ukraine and Uzbekistan, to name a few places, processing these into natural pigments. We purchase resins, gums and plants from India, Kenya and Malaysia to make natural varnishes and painting mediums.
Our mission is to provide the largest variety of natural pigments, paints and other professional artists' supplies, enabling us to bring you a selection that makes shopping for rare and hard-to-find art materials easy. Our objective is to promote the education and use of these materials among artists by providing detailed information for their employment in encaustic, fresco, oil, watercolor and tempera painting.
