Saturated Polyester Resin for Automotive Paints
Saturated polyester resins for automotive paints are engineered to deliver superior durability, weather stability, and long-term gloss retention in demanding vehicle environments. Their balanced molecular structure supports high cross-link density, smooth film formation, and excellent compatibility with melamine and isocyanate curing systems.
These resins are widely applied in OEM & refinish coatings, bumper paints, car body panels, plastic parts, powder-clear topcoats, and metallic basecoats. The main raw ingredients include purified terephthalic acid (PTA), isophthalic acid (IPA), neopentyl glycol (NPG), cyclohexane dimethanol (CHDM), adipic acid, and controlled polyol blends. Formulation additives often include UV absorbers, HALS stabilizers, leveling agents, flow modifiers, adhesion promoters, and anti-yellowing packages to guarantee premium automotive performance. The polymer architecture is optimized for flexibility, scratch resistance, and high-definition surface appearance. High-weather UV-boosted polyesters for metallic auto paints can support water-borne, solvent-borne, and powder topcoat systems depending on customer demand.
