Dow Corning offers seven distinct families of release coating technology, including solventless, solvent-based and emulsion coatings and a choice of four cure chemistries--platinum, low-platinum, rhodium and tin.

Their general topics include high pressure NMR cells, the use of high pressure infrared spectroscopy to study catalytic mechanisms, processing spectroscopic data, carbonylation of methanol to acetic acid and methyl acetate to acetic anhydride, rhodium catalyzed hydroformylation, alkene/CO copolymerization, the use of spectroscopy in metallocene-based polymerization catalysis, and hydrogenation.
