Concerning rheological stabilization of coatings, there is a trend to move away from hazardous raw materials, with preference given to the use of bio-based and sustainable chemistries, wherever possible. Testing of new organic additives shows good dispensability and ease of activation.
Ribbon polysilicates are inorganic rheological additives that can provide a strong shear-thinning flow profile and thixotropic properties. This article explores their use as an alternative to standard clay-based additives in waterborne coatings.
