  FTIR Ellipsometry as a Tool for Studying Organic Layers: From Langmuir-Blodgett Films to Can Coatings

  摘要：

  The capabilities of infrared ellipsometry to examine structurally various thin organic layers deposited on different substrates are demonstrated in this contribution. The presented examples involve. Langmuir-Blodgett film on gold substrate, anisotropic film of polystyrene on a silicon wafer, implanted fluorinated surface layer into a bulk polyethylene fuel tank and can coating deposited on electrolytically-plated steel (tinplate). Different calculational procedures were used to determine the film optical constants and thickness.

  The present invention provides a polyvinyl chloride plastisol composition characterized by containing a specified epoxy resin, a blocked isocyanate and, if necessary, a latent curing agent for an epoxy resin as tackifiers. This plastisol composition is excellent in storage stability and can strongly adhere to various metals and various undercoats of metals (such as electro-deposit) by baking even at a relatively low temperature to give a coating which is free from blowing and exhibits excellent adhesion after the immersion in hot water or the heating. Therefore, the composition is useful as a body sealer or undercoat for an automotive body.
