Behaviour o( associative thickener solutions The HEUR thickener with a flexible backbone behaves like a Maxwell fluid, as seen in Fig. 2 and reported by several authors . By calculating the high frequency storage modulus, the number of elastically effective chains per unit volume is
These thickeners offer substantial benefits to the coating formulator in comparison to the traditionally used thickeners. 2 PUR associative thickeners are a group of synthetic thickeners characterized by a relative low molecular mass (about 10,00050,000). They permit the formulation of waterborne coatings, with rheological properties virtually
Dec 30, 20160183;32;dry screening ore efficiency Berry Good Farms. New Associative Thickeners and Their Use In Waterborne and High . This article examines the thickening action of both types of associative thickeners, PCI Digital Editions 183; PCI China . Optimal performance is reached if the coating formulation is adjusted to suit all ingredients
The thickener used was a commercial polyether urea polyurethane associative thickener, supplied at 25% solids in 8020 waterdiethylene glycol ether; specific gravity 1.03; Mw 30,865; Mn 16,770; polydispersity 1.8405.
Associative thickening with other formulation ingredients 2 Incorporation It is recommended that PURE THIX 1450 be directly added to the water phase formulation. This dry form of the associative thickener polymer can be mixed into water at room temperature, but heat up to 40 60 176;C speeds up the incorporation. Turbidity at higher

ACRYSOL DR72 associative thickener is a synthetic, liquid, anionic rheology modifier that provides a single, low cost/ high performance alternative to cellulosic thickeners in
RHEOLATE174; 299 Highly Efficient and Strongly Shear Thinning Associative Thickener RHEOLATE 174; 299gives strongly shearthinning flow behaviour and a low highshear viscosity. Lowshear viscosity is less than with the acrylic thickener. Sag resistance on spray applied panels is much
In associative thickening mechanism, the thickening efficiency is not only come from the molecular weight of the thickener but also come from the interaction of the hydrophobic groups in the thickener with the paint raw materials such as latex, pigment, surfactant, dispersant etc.
A polyether urea, polyurethane associative thickener used in lowVOC formulation. It provides efficient thickening in high and midshear viscosity ranges often without the need of a secondary thickener.
based and Polyether Polyol based associative thickeners with superior performance in difficult systems such as those containing high salt levels or with extremes in ph.
Aqueous solution viscosity Associative thickeners were removed from their cosolvent (by precipita tion and drying) and redissolved in distilled water. Increments of the wetting agent (Tergitol 15S9) were added to associative thickener solutions made by dissolving the polymer in deionized water.
