Challenges in water-based coating formulations
Water-based coatings can be sensitive to surface tension, foam, pigment compatibility, pH, rheology balance and application conditions. Additives help formulators improve stability, processing and surface appearance.
Foam & Microfoam
Foam can appear during grinding, mixing, filling or application, leading to defects such as craters, pinholes, weak film appearance and poor finish.
Poor Pigment Dispersion
Inadequate wetting and dispersion can cause pigment flocculation, floating, flooding, low gloss, poor hiding and inconsistent color strength.
Flow & Leveling Issues
Uneven surface tension or poor leveling can result in brush marks, roller marks, orange peel, poor smoothness and uneven coating appearance.
Adhesion Problems
Water-based coatings may need better bonding support on metal, plastic, wood, concrete, glass or difficult substrates.
Rheology Instability
Poor viscosity control can affect sag resistance, anti-settling, application feel, storage stability and film build.
Storage Stability
Settling, separation, viscosity drift and pigment instability can affect finished product quality during storage and transport.
