PHENOXY PK™ HH Resin
Product Description
PHENOXY PK™ HH resin has a high viscosity compared to most PHENOXY™ resins. 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, and carbon fibers, and plastics such as nylon and polyester (PET). PHENOXY PK™ HH resin may 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™ HH resin is soluble in many polar, aprotic solvents such as MEK, cyclohexanone, and glycol ethers.

Storage
PHENOXY PK™ HH resin 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 product has a shelf life of 10 years from date of manufacture. The product should not be exposed to direct sunlight. Phenoxy resins may absorb water, ~1% by weight, if exposed for long periods of time to the atmosphere. Pellets can be dried at 80 - 90 ⁰C if desired
