Technical Manager Crayvallac Additives, Research Center of Arkema
Arkema Coating Resins
François VETTIER obtained a chemical engineering degree with a specialisation in polymer materials at ENSC of Montpellier (France) in 2006. He also graduated from the IFP-School in petrochemical and polymer processing technologies. This engineering degree was obtained in partnership with CRAY VALLEY whilst working as a chemist in their additives laboratory.
He has worked for four years as Application Laboratory Manager for Crayvallac Additives (now part of ARKEMA) and also had some responsibilities offering technical assistance for this business and supporting the European distributors. For the last 3 years, he has been especially supporting customers of Crayvallac additives for Adhesives & Sealants.
Enhanced rheological properties using polyamide additives in high tack adhesives based on silyl-terminated polymers
Polyamide additive technology has become a market reference in order to achieve the required rheological properties in many systems including Adhesives & Sealants.
In parallel, Silyl-Terminated-Polymer technology increases its market share with high growth rates in many sectors such as construction or transportation. Additionally, needs for High Tack systems are increasing, as Adhesives are replacing mechanical fasteners and more generally enhancing the end properties in application areas when specifically needed.
For these applications, Polyamide additives stand for a tool of prime interest so as to achieve a suitable rheological profile with good compromise between high early grab and enhanced workability.
A brief introduction of the Polyamide technology, in terms of chemistry and physical properties, will be shared. The paper will then focus on practical examples adapted to STP based High Tack formulations, showing different methods of characterisation and the performance of different additives regarding these properties.
Finally, the performance of a newly developped Polyamide product will be exposed and the differentiation it brings to the formulators.
