Polyurethane Adhesive Ingestion

Topics in Companion Animal Medicine, 2013
Polyurethane adhesives are found in a large number of household products in the United States and are used for a variety of purposes. Several brands of these expanding wood glues (those containing diphenylmethane diisocyanate [MDI]) have the potential to form gastrointestinal (GI) foreign bodies if ingested.

Silane Effects on Adhesion Enhancement of 2K Polyurethane Adhesives

Langmuir, 2023
With excellent properties such as great flexibility, outstanding chemical resistance, and superb mechanical strength, two-part polyurethane (2K PU) adhesives have been widely applied in many applications, including those in transportation and construction.

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 ...

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 ...

Neutrophil adhesion on phosphorylcholine-containing polyurethanes

Biomaterials, 1998
Polyurethanes have been synthesized using glycerophosphorylcholine (GPC) as a chain extender. By altering the ratio of GPC to butanediol (BD), a series of polymers was obtained composed of different contents of phosphorylcholine. Bulk and surface characterization of the polymers was carried out.

Adhesive Polyurethane Liners for Anterior Restorations

Journal of Dental Research, 1968
Polyurethane-type compositions were developed as adhesive liners for poly(methyl methacrylate) restorations. Several polyglycol-diisocyanate mixtures had excellent adhesion to human dentin when applied to moist teeth in vitro. Conventional acrylic restorations became durably bonded when applied on top of these urethane liners within 15 to 30 minutes.

Adhesion of aqueous polyurethane adhesive to human hair

International Journal of Adhesion and Adhesives, 2014
Abstract Adhesion of a water-based polyurethane adhesive to a human hair has been studied using the microbond test. Adhesion promotion using a silane coupling agent and air plasma treatment was compared. The results show that after air plasma treatment, the interfacial shear strength (IFSS) between the polyurethane and human hair was increased from 3.

Adhesion properties of polyurethane pressure-sensitive adhesive

Journal of Adhesion Science and Technology, 2013
In this study, the adhesion properties of polyurethane (PUR) pressure-sensitive adhesive (PSA) were investigated. The PUR-PSA was prepared by the cross-linking reaction of a urethane polymer consisting of toluene-2,4-diisocyanate and poly(propylene glycol) components using polyisocyanate as a cross-linking agent.
