BYK develops coupling agent for glass fibre compounds
February 20, 2015 - Germany
BYK Additives & Instruments, one of the world’s leading suppliers in the field of additives and measuring instruments, has developed a new coupling agent named SCONA TPPP 9212, useful in polypropylene glass fibre compounds.
SCONA TPPP 9212 is characterized 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 per cent maleic anhydride is exceptionally high, enabling considerable improvement to be achieved in the compounds’ mechanical properties, even with a low dosage.
The new coupling agent 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 characterized by the reduced number of cleavage products compared to melt grafting, BYK reported.
An additional flushing process following the chemical conversion removes volatile components, resulting in the coupling agent having a very low Volatile Organic Compound (VOC) content. This low VOC content permits the processor in turn to manufacture polypropylene glass fibre compounds with extremely low VOC emissions.
The coatings, inks and plastics industries are among the main consumers of BYK additives. Testing and measuring instruments from BYK can effectively evaluate the quality of colour, gloss and appearance as well as the physical properties of paint, plastic and paper products and are an important part of quality control.
