Electroless copper plating of insulating substrates, such as printed circuit boards, typically requires the pre-deposition of a catalyst layer onto the surface to initiate the chemical reactions. Pd/Sn based catalysts are widely used, but carry a hig

Cleaning of RTM moulds – the problem! The removal of loosely bound or weakly adsorbed contamination from surfaces can usually be achieved using conventional cleaning methods such as solvents or proprietory aqueous-based cleaning solutions. However,

Copolymers of acrylonitrile with a furfuryl alcohol resin have been prepared by a free radical reaction, and have been characterized by n.m.r. and i.r. spectroscopy. Their t.g.a. has been performed in air and in a nitrogen atmosphere, to permit the r
