PHENOXY™ PKHB+

PHENOXY™ PKHB+ is a low-viscosity phenoxy resin offering excellent thermal stability, adhesive strength, and vapor barrier properties. It can be crosslinked with isocyanates, melamine, or phenolic resins for enhanced chemical resistance and adhesion to materials like steel, aluminum, glass, and plastics. Used in single-pack epoxies with latent hardeners like dicyandiamide, it improves toughness and adhesion. Soluble in polar, aprotic solvents like MEK, cyclohexanone, and glycol ethers.
