Former Rockwood Additives

The perfect fit:

Rockwood rheology additives are now a part of BYK

As part of one of the most innovative and fastest-growing specialty chemicals companies in the world, BYK is a leader in wetting and dispersing additives, in air-release, defoaming and surface-improving additives as well as in wax additives - and now also rheology additives.

Alongside the familiar products and technical services, a significantly enhanced product range will also be at your disposal. With our 13 production and 19 laboratory sites as well as around 1,800 employees, we are your reliable business partner. 

With the expansion of the BYK portfolio we have strengthened our rheology product group and opened up new markets, such as exploration technology oil/gas, cosmetics and personal care or the construction industry.

The new BYK additives optimize the viscosity in the individual systems. They improve the processability and storage stability and enable a thicker application of layers.

BYK's new line of rheology additives is used in a wide range of applications. Find here your market and BYK's additive recommendations.
