Nonisocyanate polyurethanes for adhesives and coatings

First International IEEE Conference on Polymers and Adhesives in Microelectronics and Photonics. Incorporating POLY, PEP & Adhesives in Electronics. Proceedings (Cat. No.01TH8592), 2002
Polyurethane adhesives and coatings are widely used in Microelectronics and Photonics. The novel matrix of advanced nonisocyanate polyurethane (NIPU) coatings and adhesives are formed from two oligomers, one of them contains terminated cyclocarbonate groups (CC-oligomer), second terminated primary amines groups. As a result of forming an intramolecular

Addition of Silica to Polyurethane Adhesives

The Journal of Adhesion, 1992
Abstract The influence of the addition of silica (Aerosil-200) (5-25 wt%) to polyurethane adhesives on their adhesion properties with non-chlorinated and surface-chlorinated rubbers has been studied. The chlorinating agent was Trichloroisocyanuric acid (TIC) in 2-butanone solution at a concentration of between 1 and 9 wt%.

Polyurethane Structural Adhesives

1986
Polyurethanes were first discovered by Otto Bayer and coworkers at I. G. Farbenindustrie, Germany, in the late 1930s. The first products were obtained by reacting an aliphatic diisocyanate with an aliphatic diamine or dio1.1,2 These materials soon found commercial uses and were marketed under the trade names of Irgamid U, for plastics, and Perlon U for

Polyurethane- and Isocyanate-Based Adhesives

1990
The most important polyurethane adhesive components continue to be toluene diisocyanate (TDI) (I)*, diphenylmethane-4,4’-diisocyanate (MDI) (VIII), polymethylene polyphenyl isocyanate (PAPI) (XV), and triphenylmethane triisocyanate (Desmodur R) (III) together with various polyester and polyether glycols.

Polyurethane dispersions for adhesive applications

Pigment & Resin Technology, 1997
Discusses the manufacture of polyurethane dispersions. States that excellent properties (including good early green strength, high ultimate bond strength, good open time, good adhesion to a variety of substrates, high heat resistance, low heat activation temperature, ability to be blended with other water based polymers and additives) can be obtained ...

Cryogenic Properties of a Polyurethane Adhesive*

Journal of Macromolecular Science: Part A - Chemistry, 1969
Abstract Differential thermal analysis (DTA), rebound resilience, and tensile proerties of a polyurethane adhesive were measured at cryogenic temperatures. The experimental methods are described, and test results which aid in evaluating the polyurethane for use at low temperatures are discussed.
