Phase Behavior and Rheology of Latex, Thickener, Surfactant Mixtures and Liquid Crystal Based Compositions for Printing High-Efficiency Flexible Electronics
… ethoxylated urethane (HEUR) associative thickeners in water. The dispersant was mixed at various concentrations (0-2% by weight) with HEUR thickeners at 1% by weight concentration in the aqueous medium. This study is an integral part of our attempts to determine mechanisms of …

Development and Implementation of Dispersion Phase Diagrams (DPDs) for Four Different Hydrophobically Modified Ethoxylated Urethane (HEUR) Based Acrylic Paint Systems
… The other main components of paint include associative thickeners, surfactants, pigments and fillers with the thickener being the primary area of focus for this study.</p> <p>The relatively simple system of latex, associative thickener and surfactant has been studied extensively. These …

Syneresis and Rheology Mechanisms of a Latex-HEUR Associative Thickener System
… hydroxyethyl celluloses (HECs), a type of non-associative thickener that is relatively inexpensive and synthesized from cellulose, which is abundant. However, coatings that are modified with HECs tend to suffer from poor leveling and syneresis (phase separation). HECs have since been replaced …

Einstufen-Synthese und Charakterisierung amphiphiler Sternpolymere als multifunktionale assoziative Verdicker
Typische assoziative Verdicker für wässrige Systeme basieren auf linearen, doppelt hydrophob endmodifizierten Poly(ethylenglykolen) (PEGs). Diese Polymere aggregieren aufgrund ihrer Struktur in wässriger Lösung und bilden ein Netzwerk aus verbrückten Polymer-Mizellen. Dabei kann ein Polymer-Molekül …
