Oligomers for Flexibility
Various Bomar® oligomers can be used to impart flexibility to coatings, inks, and pressure sensitive adhesives (PSA). These oligomers can be used as the main oligomer or as a co-oligomer. Bomar oligomers are used in applications ranging from thermoformable coatings to highly stretchable inks. Please speak with our Sales and/or Technical Teams to learn more about the properties of the oligomers.
