Polyols for solvent-free adhesives for
the production of isocyanate-terminated prepolymers
The Bayer polyols form isocyanate-terminated prepolymers when combined
with monomeric polyisocyanates of the Desmodur® and Mondur®
range. For the production of adhesives for the packaging and film lamination industries,
use is made above all of Desmophen® polyester resins and Acclaim®,
Arcol® and Multranol® polyether polyols.
Properties:
The choice of polyol grade controls the specific adhesion to a wide
variety of plastic films and the viscosity of the adhesive. Whereas
the polyester grades have particularly high specific adhesion to
various materials, formulations containing the polyether grades
are noted above all for their outstanding viscosity and the superior
bond resistance.
Uses: The above-mentioned polyols have proved valuable
above all for the production of adhesives for flexible bonds.
Advantages:
- High strength and resistance of the bonds
- Good adhesion to different materials

our technical experts will be pleased to give detailed advice on specific
applications and on the formulation of adhesives based on polyols.
