Clay thickener for use in water-based systems and joint compounds containing such compositions. |
摘要 |
<p>The present invention relates to a thickener composition comprising clay deposits and modified cellulose. It has now been discovered that a combination of a clay deposit and a modified cellulosic material provides thickening in water-based systems and particularly, in joint compound formulations. The composition shows a surprising thickening effect when added to water-based systems which would not be expected from the performance of these compounds individually as thickeners.</p> |
