Oxazoline Functional Polymers

Low-toxicity cross-linkers for enhanced adhesion and curing.
Provide excellent performance in coatings, primers, and adhesives with long pot-life.

Reactive Polymer Solution for Strong, Flexible and Moisture-Resistant Adhesion

NAGASE’s oxazoline-grafted polymers are highly reactive, low-temperature curable cross-linkers that bond efficiently with –COOH functional structures. With excellent adhesion properties, these polymers are well-suited for use in coatings, primers, and adhesives applied to polyester and other engineering plastics.

Their key advantages include a long pot-life, no formation of reactive by-products, low toxicity, and broad compatibility across a range of substrate types. These materials improve moisture resistance, drying speed, heat resistance, and film integrity in various formulations.

NAGASE supplies oxazoline-functional polymers globally for high-performance industrial coatings, adhesives, and printing systems – backed by application expertise and logistical support.
