Novel dust-free associative thickeners from BYK
BYK is presenting novel associative thickeners for use in coating applications as well as in adhesives and sealants at the European Coatings Show 2023. Unlike other such additives in powder form, they are supplied as dust-free flakes.
Associative thickeners are usually offered as aqueous solutions and require the addition of a number of raw materials, including biocides that prevent microbial infestation. The situation is different with solid associative thickeners, which are usually in powder form. However, this powder form has the disadvantage that dust is released during processing, so increased occupational safety measures, such as the use of dust masks, may be required. In BYK's anniversary year, the new RHEOBYK-7650, RHEOBYK-7670 and RHEOBYK-7690 associative thickeners solve many of these problems.
All three products are solid additives in a unique delivery form: they are supplied as flakes that do not tend to form dust, yet are easy to incorporate into the mill or topcoat stock and as a solution in the formulation. By using the new associative thickeners, the rheology can be adjusted over the entire shear range. Due to their excellent product properties, RHEOBYK-7650, RHEOBYK-7670 and RHEOBYK-7690 are recommended for use in various coating applications as well as in adhesives and sealants. These product highlights will be presented to the public for the first time at ECS 2023 at the BYK booth in Hall 3A, Booth 124 and as a public product presentation on the exhibition grounds.
