PHENOXY™ PKHW 38

PHENOXY™ PKHW 38 is a waterborne, anionically-stabilized colloidal dispersion of PHENOXY™ resin PKHC for thermoset coatings and adhesives. It is a low-viscosity, non-Newtonian fluid at room temperature, offering excellent thermal stability, adhesive strength, and vapor barrier properties. Crosslinked with isocyanates, melamine, or phenolic resins, it provides strong chemical resistance, hardness, and adhesion to substrates like steel, aluminum, glass, carbon fibers, and plastics. Recommended crosslinking levels are 5-20 phr based on resin solids.

Processing Information
  • Phenoxy PK™ HW-38 should be stored in a dry place, in its sealed original container, at temperatures between 0°C - 40°C (32°F - 104°F). Under these storage conditions the shelf life is 12 months from date of manufacture. The product should not be exposed to direct sunlight.
  • The addition of PKWH-38 to ambient cure 2k waterborne formulations can improve ultimate film hardness, shorten dry-to-touch times, and improve gloss. Physical properties can be further enhanced with the use of ambient-cure crosslinkers such as aliphatic isocyanates, carbodiimides, polyaziridines, and epoxy silanes. Crosslinkers such as alkylated phenolics and melamine’s are readily dispersed in PKHW-38 to provide shelf-stable, single pack, thermoset formulations. All properly formulated coatings of PKHW-38 display excellent flexibility and surface hardness. PKHW-38 typically contains less than 8% by weight volatile organic compounds (VOC’s) and triethylamine.
