BYK introduced the new non-dusting associative thickeners RHEOBYK-7650, RHEOBYK-7670 and RHEOBYK-7690.
Associative thickeners are typically offered as aqueous solutions and require the addition of a variety of raw materials, including biocides that prevent microbial contamination. On the other hand, solid associative thickeners are usually in powder form. The disadvantage of their powdery nature, however, is that dust is released during processing, which may require increased occupational safety measures, such as the use of dust masks.
Now, BYK has launched new associative thickeners RHEOBYK-7650, RHEOBYK-7670 and RHEOBYK-7690 which solve many of these problems. These products are solid additives in a single delivery form: they are supplied as flakes which do not tend to form dust and yet are easy to incorporate into the millbase or into the letdown as well as a solution into the formulation. Using the new associative thickeners, the rheology can be tuned over the entire shear range.
Due to their excellent product properties, RHEOBYK-7650, RHEOBYK-7670 and RHEOBYK-7690 can be used in a wide range of coatings, adhesives and sealants applications.
The products will be available for the first time at the BYK booth (booth 124, hall 3A) at the European Coatings Show 2023.
