New BYK coupling agent:
SCONA® TPPP 9212 for polypropylene glass fiber compounds

Wesel, February 5, 2015. - BYK has developed a new coupling agent for use in polypropylene glass fiber compounds: SCONA TPPP 9212, which 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 fiber 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 fiber 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. 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 fiber compounds s with extremely low VOC emissions, as demanded by the automotive industry, for example.

About BYK Additives & Instruments: 

BYK Additives & Instruments is one of the world’s leading suppliers in the field of additives and measuring instruments.Additives are chemical substances which, when used in small quantities, improve product properties such as scratch resistance or surface gloss. Manufacturing processes are also optimized by the addition of additives.
The coatings, inks and plastics industries are among the main consumers of BYK additives. Yet with oil production, the manufacture of care products, paper surface finishing, the manufacture of adhesives and sealants, or construction chemistry, too, BYK additives improve the product characteristics and production processes.
Testing and measuring instruments from BYK can effectively evaluate the quality of color, gloss and appearance as well as the physical properties of paint, plastic and paper products and are an important part of quality control.As a globally operating specialty chemicals company, BYK has production sites in Wesel, Kempen, Moosburg and Schkopau (Germany), Deventer and Denekamp (Netherlands), Widnes (UK), Wallingford, Chester, Gonzales, Louisville (USA) and Tongling (China).

BYK‘s instrument section (BYK-Gardner) is based in the Upper Bavarian town of Geretsried.

Today the company employs around 1,800 people worldwide and forms part of the ALTANA Group.
