Bentone® SD-3 is an organic derivative of hectorite (smectite) clay-based highly efficient rheological additive. It is designed for use in coating systems with a wide range of solvent polarities. It offers improved dispersibility characteristics and provides stable viscosity, controls sag and suspends pigments. It proves to be a cost-effective alternative to other organoclay rheological additives and fumed silica.
It shows dispersion readily when added directly at the pigment-grinding stage and improves batch-to batch consistency.
Bentone® SD-3 is used for applications like acrylic paints, anti-corrosion maintenance paints, automotive finishes/primers, bituminous coatings, chlorinated rubber paints, decorative coatings, gravure printing inks, hammer finishes, industrial finishes, marine paints, oil paints, polyester paints, primers, and vinyl paints (high build).
It is suitable for alkyd, epoxy and PU two pack-systems.
