R&D Manager PPSV-MS
Kaneka Belgium N.V.
In 1996 Luc Peeters graduated as PhD in polymer chemistry at the University of Antwerp on electrically conductive polymers. The following 3 years he studied at the University of Antwerp the thermal stability of oil-water emulsions for the hot rolling of aluminum.
In 2000 he became scientific assistant in the Belgian Army and set up a synthesis lab to make fingerprinting material for determination of war and nerve gasses.
From 2001 till 2007 he was Research Chemist at DuPont de Nemours responsible for the development of resins for automotive coatings.
In 2007 he became R&D manager at Kaneka Belgium where he is responsible for the development of sealants and adhesives based on MS PolymerTM.
Biobased lignin building blocks to improve the properties of silane terminated polyethers
The incorporation of biobased lignin molecules in silane terminated polymers and the effect on the properties was studied.
Lignin is one of the most abundant available biopolymers, between 60 and 70 million metric tons of lignin are available from wood pulp and paper industry. Around 95% is currently burned as it is not yet a commodity product which can be used as a building block due to its variety in composition.
A research study was initiated to incorporate lignin based bio-aromatic building blocks into MS PolymerTM. One of the major hurdles to take was the unexpected incompatibility of the bio-aromatics with the MS PolymerTM. A solution was found by modifying the lignin molecules with non-reactive and reactive groups resulting in compatible bio-aromatics.
The non-reactive molecules could be blended in the MS PolymerTM and the final formulations, whereas the reactive molecules could be build-in in the silane terminated polyethers and acrylates. Results will be shown that the thermal and UV-stability could be significantly increased without affecting the standard properties.
Final a hard coating or primer could be developed with high content of biobased material which shows excellent adhesion to an MS PolymerTM based sealant and high chemical resistance.
The study shows a high potential of the lignin bio-aromatics to increase the biobased part in sealants and adhesives.
