Description

1. Dispersant: STPP acts as a dispersant, aiding in the even distribution of pigment particles within a liquid medium, such as paint or ink. By preventing pigment agglomeration, STPP helps maintain a stable and homogeneous mixture, which is crucial for achieving consistent color and appearance in the final product.
2. Suspension Agent: STPP helps to suspend pigment particles in the liquid medium, preventing them from settling at the bottom of the container over time. This ensures that the pigment remains uniformly distributed throughout the product, enhancing its shelf-life and usability.
3. Improved Color Performance: STPP can enhance the color performance of pigments by promoting better wetting and dispersion of pigment particles. This can lead to improved color intensity, brightness, and overall color quality in the final product.
4. pH Stabilizer: STPP can help stabilize the pH of pigment dispersions, particularly in alkaline systems. This is important for maintaining the stability and performance of the pigment, as well as preventing undesirable reactions or degradation of other components in the formulation.
5. Process Aid: In pigment manufacturing processes, STPP can serve as a process aid by facilitating the mixing and milling of pigment particles, improving process efficiency and product quality.
