Phenoxy PK™ HC

PHENOXY PK™ HC by Huntsman is an average viscosity compared to most phenoxy resins designed for thermoset coatings. It is a tough, ductile, amorphous, thermoplastic polymer having excellent thermal stability, adhesive strength and vapor barrier properties. It may be crosslinked by reacting its hydroxyl functional groups with isocyanates, melamine resins, or phenolic resins. It exhibits excellent chemical resistance, hardness and adhesion on many substrates including steel, aluminum, glass, & carbon fibers, and plastics such as nylon and polyester (PET). It also be formulated in single-pack epoxies containing latent hardeners, such as dicyandiamide, providing improved toughness and adhesive strength on substrates when properly cured. Phenoxy PK™ HC is soluble in many polar, aprotic solvents such as MEK, cyclohexanone, and glycol ethers. It has a shelf life of 10 years.
