Rheological additives are indispensable components in the formulation of modern coatings, playing a crucial role in determining how a coating behaves during storage, application, and curing. NINGBO INNO PHARMCHEM CO.,LTD. extensively utilizes and understands the science behind these additives, particularly organic bentonite, to enhance coating performance across diverse sectors.

The primary function of a rheological additive is to modify the flow properties, or rheology, of a liquid system. In coatings, this means controlling viscosity, preventing settling of pigments and fillers, and ensuring optimal application characteristics. Organic bentonite, a type of organoclay, is highly effective in solvent-based systems. Its ability to form a gel-like structure at rest provides thixotropy, which is essential for preventing sagging on vertical surfaces and maintaining paint viscosity during storage. This property also ensures that pigments remain uniformly dispersed, leading to better color consistency and film integrity.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that the choice of rheological additive depends heavily on the solvent system's polarity. While some organoclays require a polar activator for optimal dispersion, advancements have led to self-activated variants that simplify the formulation process, especially in medium to high polarity systems. These additives contribute to improved sag resistance, enhanced anti-settling, and better overall stability. Whether for marine coatings, industrial paints, or printing inks, the strategic use of rheological additives like organic bentonite, as championed by NINGBO INNO PHARMCHEM CO.,LTD., is key to achieving high-performance, user-friendly, and durable coating solutions.
