Polyols for the production of prepolymers
Bayer polyols marketed under the names Acclaim®, Arcol®, Multranol®
(polyether polyols) and Desmophen® (polyester polyols) form isocyanate-terminated
prepolymers when combined with monomeric polyisocyanates of the Desmodur®
and Mondur® range.
Properties: The Desmophen® polyester grades
differ with regard to their adhesion and viscosity. Whereas the
polyester grades have particularly high specific adhesion to various
materials, formulations containing our polyether grades are noted
for their outstanding viscosity and the hydrolytic stability of
their bonds. The fatty acid modified polyester grades are used mainly
for producing bonds with particularly good resistance to hydrolysis.
Uses: The polyol grades mentioned above have produced particularly
good results in the production of Adhesives and Specialties for the
bonding of plastic, metal and glass in a variety of applications.
Advantages:
- high strength and resistance of the bond
- wide variety of adhesives can be produced
- flexible even at low temperatures
Contact us and our technical
experts will be pleased to give detailed advice on specific applications
of Bayer products in the transportation industry.
