Polyesters provide a strong balance of toughness, flexibility, and chemical resistance, making them versatile for many industrial applications. Unsaturated polyesters are widely used in composites through styrene/peroxide curing, while saturated grades excel in durable coatings and films. Polyamides are known for their high toughness, flexibility, adhesion, and chemical resistance, which make them excellent candidates for demanding environments. Used in coil coatings, packaging inks, adhesives, and flexible films, as well as in hot-melt and flexo/gravure ink resins.
