Hydrophobic Thickeners

A GUIDE TO UNDERSTANDING AND MIXING THICKENERS

However, most thickeners, due to their hydrophobic groups, resist wet-out upon contact with water and could float on the surface for hours. Mixing operators are then forced to carefully sift and add powders only as fast as the liquid will take them. Adding powders slowly into a small batch of vigorously agitated liquid may provide enough time for individual solid particles to hydrate. But in a ...

Thickeners and Rheology Additives - chem tech - product - ACAT

The hydrophobic as well as the hydrophilic polymer segments of the thickener can interact with pigments and can provide additional wetting and dispersing effects. Colour acceptance in tinting is increased, settling tendency and rub-out problems are reduced by the interaction with pigments and fillers. Furthermore, in general the molecular weight of polyurethane thickeners is significantly ...

hydrophobic structure. One thickener molecule can participate in two or more micelles. Micelles are linked together physically, i.e. individual thickener molecules form micelles with other thickener molecules and also interactions with hydrophobic emulsion particles or other hydrophobic formulation ingredients. The association immobilises these components and thus leads to the thickening ...

These hydrophobic thickeners generally act to create more wormlike micelles and encourage more non‐Newtonian flow behaviour. In practice, they also act to push the salt curve to the left. This means they can increase the product viscosity at low salt levels, making the product easier to thicken with brine. High molecular weight, polymeric non‐ionic surfactants can also be added to an alkyl ...

Selecting Rheology Modifiers for Adhesives

Associative thickeners form intermolecular associations with dispersed particles (resin or filler). These interactions are the result of the presence of insoluble hydrophobic groups along the water-soluble thickener’s molecular backbone. Once added to water, the hydrophobic groups assemble into aggregates or micelles, and a three-dimensional network is formed which causes the medium’s ...
