Polyvinyl butyral, an excellent support film for TEM filmed grids and also, the making of fine replicas for TEM

Butvar B-98 resin has been a long time favorite and excellent support film for TEM grids. It is usually dissolved 2% in chloroform. This particular grade of Butvar (e.g. B-98) has also been used as a replicating material for TEM replicas. However, the high solvency of chloroform would tend to render it not the material of choice if being used on a polymeric surface which might be changed by the solvent. The same would probably be true for ethyl acetate.
