Nichigo POLYESTER is recreate the fields of high-tech adhesives, coating binders, and resin modification.
From Current Needs into the FutureThe NIPPON GOHSEI’s high molecular weight saturated polyester resins are born from advanced polymer synthesis
technologies. Nichigo POLYESTER displays excellent adhesive performance with plastic films and moldings including
PET, polycarbonate, and vinyl chloride, and metals including aluminum and copper. Used in tandem with isocyanate,
melamine, and epoxy resins and other hardening agents, they offer increased heat resistance, solvent resistance,
and hardness. NIPPON GOHSEI offers the optimum line-up for all customer needs, including amorphous
solvent-soluble, crystalline hot melt, water-soluble, and special types.
Nichigo POLYESTER displays excellent
adhesion with woven and nonwoven materials,
plastic films and moldings, and metals including
aluminum, copper, and steel.
Denaturing through mixture with other resins,
and the addition of hardening agents such as
isocyanate, melamine, and epoxy resins, increases
heat resistance, hardness, and toughness.
Superior flexibility, weather resistance, and electrical
properties, in addition to excellent hygienic properties.
Nichigo POLYESTER displays almost no age-related
changes, and maintains stable quality over the long-term.

Applications
An adhesive-coated PET film was applied to an SUS sheet using two
forwards and backwards passes of a 2kg roller. The test specimen
was left in a 120°C environment for predetermined lengths of time.
After each specific length of time it was returned to a 23°C
environment and its adhesion was measured.
