Gabriel Performance Products

Gabriel® PKHW-35

Chemical Family: Phenoxy Compounds

End Uses: Waterborne Coating

Compatible Substrates & Surfaces: Glass

Features: High Gloss, Chemical Resistance, Improved Flexibility, Thermal Resistance, Excellent Adhesion, Improved Hardness

Gabriel Phenoxy PK™HW-35 is a waterborne anionically-stabilized colloidal dispersion of phenoxy resin PKHH designed for thermoset coatings and adhesives. The dispersion is a non-Newtonian fluid at room temperature and exhibits very slight thixotropic behavior. Phenoxy resins (polyhydroxyethers) are tough, ductile, amorphous, thermoplastic polymers having excellent thermal stability, adhesive strength, and vapor barrier properties. Phenoxy resins may be crosslinked by reacting its hydroxyl functional groups with isocyanates, melamine resins, or phenolic resins. Crosslinked phenoxy resins exhibit excellent chemical resistance, hardness, and adhesion on many substrates including steel, aluminum, glass, carbon fibers, and plastics such as nylon and polyester (PET). The recommended level of crosslinking range from 5 to 20 phr based on resin solids. PKHW-35 is compatible with most waterborne polyurethanes and acrylics at pH’s greater than 6.5. PKHW-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.
