Pigment Dispersion Troubleshooting Guide Why Pigment Dispersion Viscosity Increases During Storage—and How to Fix It Pigment Dispersion Viscosity can remain stable immediately after milling but increase after several days or weeks of storage. Reflocculation, insufficient pigment stabilization, pH changes, rheology development, temperature and additive interactions are among the areas formulators should investigate. Technical Troubleshooting Pigment […]
Water-Based Coating Stability Guide How to Improve Storage Stability in Water-Based Paints and Coatings A water-based coating can meet its initial viscosity, color and application targets yet still change during storage. Pigment flocculation, settling, rheology drift, pH movement, foam and additive incompatibility can all reduce long-term consistency. Technical Guide Water-Based Coatings Storage Stability Explore Coating […]
Wetting & Dispersion Guide Wetting & Dispersing Additives for Water-Based vs Solvent-Based Coatings A dispersing additive that works well in a water-based coating may not provide the same performance in a solvent-based system. Pigment surface chemistry, binder compatibility and the polarity of the liquid phase all influence wetting and stabilization. Technical Guide Water-Based Coatings Solvent-Based […]
Advanced Pigment Dispersion Hyperdispersant Additives for Carbon Black and Difficult Organic Pigments Carbon black and many organic pigments can be challenging to disperse because of their high surface area and strong tendency toward particle interaction. Hyperdispersant additives can help formulators stabilize these demanding pigment systems while managing viscosity, color development and pigment loading. Technical Guide […]
Foam Control Additives Antifoam vs Defoamer: What Is the Difference in Coatings? Foam is one of the most common formulation and application problems in paints and coatings. Understanding the difference between antifoam and defoamer additives helps coating manufacturers choose the right foam control solution for better surface finish, processing stability and coating quality.
