Image of Polyester Polyol for Adhesive "TL Series"

These polyester resins have excellent adhesion to various films by combining with isocyanate/adduct/isocyanurate.

Features

  • There are polyester polyol for adhesive. They are made from diacid or long chain aliphatic diacid as acid component and various kinds of glycol. We have various molecular weight of polyester polyol for the application.
  • They have excellent heat resistance and high adhesion by combining with polyisocyanate.
  • They have good versatility because of two-component type.
  • Especially,they have excellent adhesion to PET.

Applications
