Polyurethanes for solventborne adhesives
High-molecular-weight polyurethanes
terminated with hydroxyl groups are marketed under the name Desmocoll®.
Desmocoll® hydroxyl polyurethanes are polyaddition products
based on bifunctional polyesters and isocyanates.
Properties:
The Desmocoll® grades differ with respect to their crystallization
rate, solution viscosity and thermoplasticity. The Desmocoll®
grades of the 400, 500 and 600 ranges are characterized by high
to very high crystallinity. The Desmocoll® grades based on aromatic
isocyanates have a tendency to yellowing on exposure to light.
Uses: In the transportation
industry, Desmocoll® has proved ideal in the production of adhesives
for the lamination of PVC films or fabrics to various backing materials.
Advantages:
- Excellent solubility in many organic solvents
- Outstanding adhesion to numerous synthetic materials
- Lasting bonds with highly plasticized PVC (Desmocoll® 400,
500 or 600)
