PKHM-301

PKHM-301 by Huntsman is a solid, phenoxy resin melt blended with an oligomeric polyester polyol containing primary hydroxyl functional groups. It is a tough, ductile, amorphous, thermoplastic polymer having excellent thermal stability, adhesive strength, and vapor barrier properties. It may be crosslinked by reacting its hydroxyl functional groups with isocyanates, melamine resins, or phenolic resins. It provides improved reactivity due to the presence of primary hydroxyls and the lower glass transition temperature of the alloy. PKHM-301 is used in adhesives and sealants.
