Organic clay recommended dosage for solvent paints
organic clay recommended dosage for solvent paints – organoclay dosing guidelines for optimal rheology
Recommended organic clay dosage for solvent paints, providing formulators with precise guidelines to achieve optimal viscosity, sag resistance and pigment stability.
The recommended dosage of organic clay for solvent paints varies depending on solvent polarity, resin type and target rheological behavior. In solventborne systems—such as alkyds, acrylics, PU coatings and epoxy primers—the typical addition level ranges between 0.2% and 1.0%, with higher amounts needed for high-solid or heavy-pigment formulations.
The clay should be added under high shear, and polar activators may be used to enhance performance. With proper dosing, coatings achieve improved sag resistance, stable viscosity and long-term pigment suspension.
Coating formulators often struggle with determining the correct organic clay dosage to achieve optimal rheology. When they evaluate our clear guidelines—supported by laboratory application data—and test the clay’s predictable response across different resin systems, their interest increases significantly.
As they see improved sag control, better storage stability and reduced formulation variability, the desire to adopt these recommended dosages becomes immediate. With precise dosing instructions and technical support, formulators can confidently achieve consistent performance.
🔹 FAQ – Organic clay recommended dosage for solvent paints
Q1: What is the typical dosage for solvent paints?
0.2%–1.0%, depending on resin type and solvent polarity.
Q2: Do high-solids coatings need more clay?
