Development team behind CMR-free rheological additives acknowledged with the BYK Advance innovation prize

Wesel, November 16, 2015. - At BYK Additives & Instruments, a leading supplier in the field of additives and measuring instruments for the coatings, inks and construction chemistry industry, the amended labeling for N-ethylpyrrolidone (NEP), which can be found as a solvent in additives, has also necessitated adjustments to the labeling of some rheological additives. Parallel to this, an internal interdisciplinary project team has focused on developing suitable solvent alternatives.

The development team awarded this year’s BYK Advance innovation prize investigated around 70 different solvents in various coating applications, taking account of the regulations and resulting registration requirements such as REACH and TSCA, and created alternatives based on the carriers that are not labeled as CMR, amide esters (ES) and amide ethers (ET).

The new rheological additives cover the whole polarity range from high to low polarity. They control the thixotropic flow, have an outstanding shear-thinning effect and exhibit time-dependent structure recovery.

BYK-7410 ET, BYK-7411 ES and BYK-7420 ES improve the anti-sagging effect and storage stability. In addition, the rheological additives exhibit excellent substrate wetting and perfect leveling.

The award winners from the Synthesis, Rheology and Application Technology departments received the prize from Dr. Gerald Kirchner, Head of Corporate EH&S at ALTANA, in the presence of Dr. Stephan Glander, President Division BYK Additives & Instruments, and Dr. Horst Sulzbach, Head of Research & Development (BYK).

About BYK Additives & Instruments:

BYK Additives & Instruments is one of the world’s leading suppliers in the field of additives and measuring instruments.Additives are chemical substances which, when used in small quantities, improve product properties such as scratch resistance or surface gloss. Manufacturing processes are also optimized by the addition of additives.

The coatings, inks and plastics industries are among the main consumers of BYK additives. Yet with oil production, the manufacture of care products, paper surface finishing, the manufacture of adhesives and sealants, or construction chemistry, too, BYK additives improve the product characteristics and production processes.
Testing and measuring instruments from BYK can effectively evaluate the quality of color, gloss and appearance as well as the physical properties of paint, plastic and paper products and are an important part of quality control.

As a globally operating specialty chemicals company, BYK has production sites in Wesel, Kempen, Moosburg, Schkopau and Geretsried (Germany), Deventer and Denekamp (Netherlands), Widnes (UK), Wallingford, Chester, Gonzales, Louisville (USA) and Tongling (China).

Today the company employs around 2,000 people worldwide and forms part of the ALTANA Group.
