FAQs
Why do bubbles or foam form during paint production or application, and how can this be resolved?
Foam formation usually occurs due to high‑speed mixing or the presence of surfactants in the formulation. This issue is typically resolved by using defoamers, which reduce surface tension and help eliminate trapped air bubbles, preventing surface defects in the final paint film.
Why do pigments settle at the bottom of the container over time?
Pigment settling is mainly caused by poor dispersion stability. Using specialized dispersing agents creates electrostatic or steric stabilization between pigment particles, preventing agglomeration and sedimentation while improving the storage stability of the paint.
What is the function of wetting and dispersing agents?
Wetting and dispersing agents help pigments and fillers disperse evenly within the formulation. They reduce surface tension, improve pigment wetting, and prevent agglomeration, which enhances color strength, stability, and overall paint performance.
Why is compatibility between additives and other formulation components important?
Additives must be compatible with the resin, solvents, pigments, and other formulation components. Poor compatibility may lead to phase separation, haze formation, or reduced coating performance.
How can the right additive be selected for a new formulation?
Selecting the right additive requires evaluating the coating system type, production process conditions, application method, and desired performance of the final coating. Laboratory testing and consultation with technical experts are essential for making the best selection.
