Spacer film for mould and model construction, and the use thereof

摘要

The invention relates to a spacer film for mould and model construction which is produced by curing 100 parts by weight of a mixture of 45-60 parts by weight of an internally plasticised epoxy resin having a low epoxide value, 5-10 parts by weight of external plasticiser and 35-45 parts by weight of spherical, amorphous filler by means of 9-13 parts by weight of a polyamine curing agent. The spacer film is eminently suitable as the replacement for the lead or wax films used hitherto for the same purpose.
