- Better surface finish, flow and leveling
- Reduced defects such as craters, orange peel and poor leveling
- Improved adhesion on selected substrates
- Better rheology control, anti-settling and sag resistance
- Support for industrial, protective and speciality coating systems
Challenges in solvent-based coating formulations
Solvent-based systems can face issues related to pigment stability, resin compatibility, surface tension, evaporation rate, flow, leveling and substrate bonding. Additives help formulators improve coating consistency and final film performance.
Poor Pigment Dispersion
Poor wetting and dispersion can lead to flocculation, low color strength, poor gloss, poor hiding and inconsistent shade development.
Floating & Flooding
Unstable pigment systems may show pigment separation, color drift, floating, flooding and poor uniformity in the applied coating film.
Flow & Leveling Defects
Surface tension imbalance and poor additive selection can cause orange peel, roller marks, brush marks, poor smoothness and uneven finish.
Foam & Surface Defects
Air entrapment and foam-related defects can create craters, pinholes and surface imperfections during coating application.
Poor Adhesion
Solvent-based coatings may need stronger adhesion support on metal, plastic, wood, glass and other difficult substrates.
Sagging & Settling
Incorrect rheology balance can cause pigment settling, poor storage stability, sagging and inconsistent application thickness.

How to choose additives for solvent-based coatings
Selection depends on resin compatibility, solvent blend, pigment type, dosage window, application method, drying behaviour, substrate and required final coating properties.
- For pigment dispersion, choose wetting and dispersing additives based on pigment type, pigment loading and resin compatibility.
- For difficult pigments, evaluate hyperdispersants to improve stabilization and reduce flocculation.
- For surface defects, use suitable flow and leveling additives to improve film smoothness and appearance.
- For foam or air entrapment, evaluate antifoam or defoamer additives suitable for the system.
- For sagging or settling, choose rheology additives that balance viscosity, storage stability and application feel.
- For difficult substrates, evaluate adhesion promoters based on surface type and coating chemistry.
