Adhesives and Sealants Formulations with Polyester Resins

Polyester adhesives appear as clear to slightly yellow liquids or solids with excellent optical properties. Key features include good chemical resistance, thermal stability, and flexibility options ranging from rigid to highly elastic. Polyester adhesives are used in applications requiring a balance of flexibility and strength, making them ideal for composite bonding, flexible packaging, and textile lamination. 

Market trends indicate growing development of bio-based polyesters derived from sustainable resources, improved material recyclability, and circular economy initiatives within various industries. Varieties include saturated and unsaturated polyesters, thermoplastic polyesters, and modified polyesters incorporating urethane groups.
