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 at BYK Additives & Instruments.
Parallel to this, an internal interdisciplinary project team has focused on developing suitable solvent alternatives.
According to BYK, 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).
It says 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 claims its 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).

After the collapse of a drinking water pipeline in downtown Amsterdam, the Netherlands, Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment.
Lanxess’ Urethane Systems business unit (URE) is extending its collaboration with the Centre for UMass/Industry Research on Polymers (CUMIRP) at the University of Massachusetts Amherst, US. From October 2018 URE will additionally participate in Research Cluster M on Mechanics & Advanced Manufacturing of Polymers and Composites.
Sumitomo Chemical reports that its polyethersulfone (PES) micro-powder additive SumikaExcel 5003P boosts fracture toughness and resistance to micro-cracking for fibre reinforced epoxy composites over a broad temperature range without negatively impacting dimensional stability, flame/smoke/toxicity (FST), creep resistance, modulus, impact, or yield strength.
