Huntsman Advanced Materials is the world-leading source of phenoxy resins and phenoxy resin formulation.  Phenoxies are used as an additive or binder in: epoxy systems, coatings, inks, adhesives, composites, plastics,  electronics, films and fibers.

Phenoxy resins (phenoxies) are amorphous polymers that will not crystallize or build up stress concentrations.  Phenoxy resin chemistry contains no additives, have low order of residual monomers and low molecular weight extractibles. They can be used without chemical conversion that might cause shrinkage, induce stress, or produce undesirable by-products.

Phenoxy resins can be used to modify many polymer systems including polyurethanes, polyesters, polyamides, epoxies, and many thermoplastic polymers including PPS, PEEK, PET, TPU’s, polycarbonate, and nylon.  Phenoxy resins are also thermosetting with isocyanates, melamine, and phenolic crosslinkers. Phenoxy thermoset and phenoxy thermoplastic resin have a wide range of uses due to excellent mechanical properties including flexibility, toughness, adhesive and cohesive strength, as well as chemical, corrosion and heat resistance.

Phenoxy Composition

Huntsman Advanced Materials Phenoxy resins are polymers of epichlorohydrin and Bisphenol-A with medium to high molecular weights. These thermoplastic polymers have terminal hydroxyl groups as well as repeating hydroxyls along the backbone.

Phenoxy resins (polyhydroxyethers) are tough, ductile polymers having excellent thermal stability, adhesive and cohesive strength, with excellent vapor barrier properties. Phenoxy resins can also react with crosslinkers like isocyanates, phenolic and melamine resins. The solid grade Phenoxy resins vary in glass transition temperature from a low of 84°C for grade PKHB to about 97°C for PKHJ. The differences of Tg and molecular weight amongst these resins are reflected in the range of viscosities attainable at equivalent solids for solvent-borne formulations.

Comparative melt rheological data on the PKHB and PKHH grades. These properties were determined by capillary rheometry at 200°C. Both resins exhibit non-Newtonian flow behavior over the shear rate test range. At a shear rate of 1000 sec.-1 the viscosity of PKHB is 75% lower then PKHH. The melt flow index at 200°C for PKHB is approximately 65 gm/10 minutes (2.16 kg load); PKHH is about 4.4 gm/10 minutes.

Phenoxy resins make outstanding primers because of their excellent adhesion, chemical and salt spray resistance, impact and abrasion resistance, and flexibility. They may be used on metal, wood, paper, glass, and many polymeric substrates.
