PHENOXY™ PKHH is a high-viscosity PHENOXY resin known for its toughness, ductility, and excellent thermal stability, adhesive strength, and vapor barrier properties. As a polyhydroxyether, it can be crosslinked by reacting its hydroxyl functional groups with isocyanates, melamine resins, or phenolic resins. Crosslinked PHENOXY resins offer superior chemical resistance, hardness, and adhesion to various substrates, including steel, aluminum, glass, carbon fibers, and plastics like nylon and polyester (PET). PHENOXY™ PKHH can also be used in single-pack epoxies with latent hardeners, such as dicyandiamide, to enhance toughness and adhesive strength when cured. It is soluble in many polar, aprotic solvents such as MEK, cyclohexanone, and glycol ethers.
