Phenoxy Resins
(Polyhydroxyl Ethers)
Properties and Applications
Phenoxy resins, also called polyhydroxyl ethers, are high molecular weight thermoplastic polymers and thermosetting resins of epichlorohydrin and bisphenol A. These polymers have terminal hydroxyl groups as well as hydroxyl groups in every repeat unit. They are usually blended and heat cured with isocyanates, anhydrides, epoxides or other chemicals to produce thermosetting polymers.
Phenoxy resins have high adhesive and cohesive strength, flexibility, and toughness as well as outstanding chemical and heat resistance. They are available in a wide variety of forms, including liquid, solid, dissolved in solvent, and dispersed in water. They are often an excellent choice for enhancing the performance of a variety of formulated (epoxy and phenolic) resin products including coatings, composites, adhesives, and inks.
