PHENOXY™ PKHW 35

PHENOXY™ PKHW 35 is a waterborne colloidal dispersion of Phenoxy resin for thermoset coatings and adhesives. It offers excellent thermal stability, adhesive strength, and vapor barrier properties. Crosslinked with isocyanates, melamine, or phenolic resins, it enhances chemical resistance and adhesion. Compatible with most waterborne polyurethanes and acrylics, it improves film hardness, dry-to-touch times, and gloss. Crosslinkers like isocyanates and epoxy silanes further enhance physical properties. Coatings exhibit excellent flexibility and surface hardness.

Technical Details & Test Data

Processing Conditions
  • PHENOXY PK HW-35 is compatible with most waterborne polyurethanes and acrylics at pH’s greater than 6.5. PHENOXY PK HW-35 is incompatible with acidic materials; low pH media can cause loss of dispersibility and precipitation of the base resin.
  • The addition of PKWH-35 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-35 to provide shelf-stable, single pack, thermoset formulations. All properly formulated coatings of PKHW-35 display excellent flexibility and surface hardness. PKHW-35 typically contains less than 12% by weight volatile organic compounds (VOC’s) including non-HAP ethylene glycol butyl ether (butyl cellosolve, Glycol Ether EB) and dimethylethanolamine

Storage & Handling

Storage Condition
  • PHENOXY PK HW-35 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.
