Amide-imide Resins (R&D)

UNIDIC V-8000 Series Solvent Soluble Amide-Imide Resins


V-8000 series product are hardening agents for epoxy resins, which contain rigid imide structures and terminal carboxyl groups. They demonstrate excellent compatibility with general-purpose solvents and various epoxy resins, and provide superior heat resistance when cured with epoxy resins.


Inter-layer insulators, such as for semiconductors and printed circuit boards, build-up materials, solder resist materials, coverlay materials, encapsulant materials, buffer coating agents, planarizing agents, insulation inks for ink-jets, heat-resistant refractory coatings, heat-resistant adhesives, wear materials, carbon fiber reinforced materials and flame retardants.
