ACRYSOL TT-615 Rheology Modifier Description ACRYSOL TT-615 is a hydrophobically modified anionic thickener, designed to give a very pseudoplastic profile in interior/exterior latex paints. ACRYSOL TT-615 provides paints with high in-can structure and is ideal for use with thickeners designed to give high shear viscosity; to achieve the desired balance between sag and levelling properties. ACRYSOL TT-615 exhibits viscosity build comparable to high molecular weight HEC thickeners at low shear levels (see Graph 1). It demonstrates better roller spatter resistance than the cellulosics. ACRYSOL TT-615 has a very pseudoplastic rheological profile (see Graph 3) ideal to reduce settling tendencies in the paint. Delivered as a low viscosity liquid, ACRYSOL TT-615 is very easy to handle and incorporate into the paint. It is resistant to microbiological degredation, thereby avoiding viscosity loss in the paint, one of the most common problems encountered by paint manufacturers. ACRYSOL TT-615 develops viscosity by neutralisation to a pH of 7.0-10.0 (see Graph 2). Characteristics � Delivers high in-can structure � Excellent sag resistance � Imparts non settling properties � Resistant to microbe and enzyme attack � Easy to incorporate � Ideal for viscosity adjustments as a post addition Typical Properties These properties are typical but do not constitute specifications.
