basic information
**Lecture Summary** To obtain a good paint film, it is necessary to evaluate and design the affinity of the components that make it up, such as resins, additives, pigments, fillers, and solvents. The SP (solubility parameter) serves as a measure of the affinity between substances. By quantifying affinity using SP, it is possible to select the components of the paint film, including additives, to form a high-quality paint film without defects (such as craters, color bleeding, and color separation). This presentation will explain the basic concepts of SP and provide application examples.
