The Impact of Insoluble Cellulose Fibrils on the Rheology of Woter-Bosed Acrylic Sotin Point Upon Tinting

摘要

It is commonly known that waterborne formulations still suffer from several issues,and it is not always possible to obtain the same performance as with solventbome systems.One of the typical challenges with waterborne systems is related to the behavior of rheology modifiers in the presence of surfactants as well as under extreme pH conditions.The common rheology modifiers can be divided roughly into two categories,associative and non-associative.The former is typically sensitive to the presence of surfactants,and this is often seen after the tinting of the base paint.In most cases,the viscosity of the paint reduces as a consequence of disturbance in the associative network due to the surfactant's presence in the tinting paste.
