BYK has developed a new coupling agent for use in polypropylene glass fibre compounds, SCONA TPPP 9212, which is characterised by its very high content of chemically bonded maleic anhydride.
The MA groups of this coupling agent react with the amino groups of the silane of the glass fibre size, thereby producing a very stable structure. The content of 1.8% maleic anhydride is exceptionally high, enabling considerable improvement to be achieved in the compounds’ mechanical properties, even with a low dosage.
SCONA TPPP 9212 is the latest addition to the range of SCONA coupling agents for use in polypropylene glass fibre compounds, which are all based on BYK’s unique solid-phase grafting process. This gentle manufacturing process requires relatively low temperatures and for this reason, is characterised by the reduced number of cleavage products compared to melt grafting. An additional flushing process following the chemical conversion removes volatile components, resulting in the coupling agent having a very low VOC content. This low VOC content permits the processor in turn to manufacture polypropylene glass fibre compounds with extremely low VOC emissions, as demanded by the automotive industry, for example.
