We can provide good solution with Ajinomoto Fine-Techno’s core technology.


We create new value
by adding various functions based
on our core technology.

  • Core technology.1 :
    “Low temperature (~80deg.C) curing system”

    You can apply which to heat-sensitive parts or suppress heat-induced deformation.

  • Core technology.2 :
    “High temperature (150deg.C) with fast curing system (a few seconds)”

    You can shorten the curing process.
