However, it found that the proposed transaction would raise competition concerns in a number of relevant specialised markets in which one, or both, parties held significant market shares even before the transaction, the proposed takeover leading to further strengthening of these positions: DMA3 (dimethylaminoethyl acrylate - a chemical intermediate); synthetic dry strength agents (used in the paper industry); bismuth vanadate (a pigment); indanthrone blue (a pigment); SA (styrene acrylic - used for paper applications); HALS (hindered amine light stabilisers - used in plastics); and UV (ultraviolet light) filters for skin care products.
PB60, an indanthrone derivative, exhibits the greatest influence on PVDF crystallization, whereas PY138 exhibits the least.
Heubach Colour in India has recently commissioned a facility for the manufacture of Indanthrone Blue Crude (PB60).
BASF has announced the release of several new pigments: the Indanthrone blue pigment Paliogen[R]
Extensive developments are ongoing in the following areas: bismuth vanadate, quinacridone, indanthrone and naphthols," said Mr.
BASF aims to meet the requirements of its customers by offering them a broad portfolio of high-performance pigments to which the company has now added a particularly color-intensive Indanthrone blue pigment --the Paliogen Blue EH 1900 (L 6400).
High-performance organic pigments include quinacridone reds, violets, scarlets and magentas, azo condensation and isoindolinone yellows, and indanthrone blues.
Don McBride: The investment in our own Indanthrone crude plant to supply the vital ingredient for this popular automotive transparent red shade, PB bo, will enable us to control both the quality and the consistency for the crude that is key to our latest polycyclic technology.
