Features: Chemical Resistance, Improved Flexibility, Thermal Resistance
Gabriel Phenoxy PK™HS-30 PMA is a 30% NV solution of Phenoxy resin in PM acetate (PMA or Propylene Glycol Methyl Ether Acetate). 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). PKHS-30 PMA can be reduced with additional PMA to attain lower viscosities; the addition of MEK will reduce viscosities at a faster rate. The addition of diluents like xylene or toluene can also be useful. Coatings of PKHS-30 PMA exhibit excellent levels of flexibility and toughness when appropriately cured.
