Strong Thermo-tolerant Silicone-Modified Waterborne Polyurethane/Polyimide Pressure-Sensitive Adhesive.

Langmuir, 2023
A waterborne polyurethane pressure-sensitive adhesive (WPUPSA) has the advantages of low pollution and good viscoelasticity. However, its poor thermo-tolerance limits its application in the field of high temperatures.

Bacterial adhesion to functionalized polyurethanes

Journal of Biomaterials Science, Polymer Edition, 1999
The effect of fibrinogen and high molecular weight kininogen on bacterial adhesion to functionalized polyurethanes was studied. Glass slides were coated with different polyurethanes, including Pellethane, sulfonated Pellethane, phosphonated Pellethane, a zwitterionic phosphonated polyurethane, and quaternized amine polyurethanes.

Controlling cell adhesion on polyurethanes

Soft Matter, 2008
Cell attractive or non-attractive surface properties of polyurethane devices can be controlled by treating them with zirconium tetra(tert-butoxide). This gives reactive interfacial zirconium complex species that can be used subsequently to bond cell attractive peptides such as arg-gly-asp (RGD) or cell non-attractive organics such as polyethylene ...

Role of the Polyurethane Component in the Adhesive Composition on the Hydrolytic Stability of the Adhesive

International Journal of Adhesion and Adhesives, 1993
In polyurethanes based on linear polyol, isocyanate and a chain extender, the physical morphology of adhesive seems to play an important role in its overall strength characteristics. The aim of this paper is to examine how the morphology and phase separation of such polyurethane components affect the adhesive properties before and after hydrolysis.

Polyurethanes as cryogenic adhesives

Journal of Applied Polymer Science, 1965
AbstractPolyurethanes containing the polyether backbone were found to give superior adhesives at cryogenic temperatures as compared to epoxy resins. However, the adhesives showed poor performance at 250 and 400°F. The adhesives were prepared from 2,4‐toluene diisocyanate (TDI)‐terminated polyether polyols and cured with 3,3′‐dichloro‐4,4 ...

Signally improvement of polyurethane adhesive with hydroxy-enriched lignin from bagasse

, 2020
Acetic acid lignin (AAL) obtained from Bagasse was used as a partial substitute of polyols for polyurethane (PU) adhesive due to the presence of reactive sites, i.e. aliphatic and aromatic hydroxyl groups, in its structure.
