Abstract
A multi-part acrylic cold curing composition for metallography moulds to produce a metallography mount is described. The composition has a storage stable solid part and a storage stable liquid part. The parts are operable to form a mixture which polymerises to a solid mass upon mixing of the parts together. The solid part comprises polymer powder and initiator and the liquid part comprises acrylic monomer and optionally activator or accelerator. The initiator is present in an amount effective to polymerize the acrylic monomer component upon being mixed with the liquid part. The composition comprises a cyclic ester side group containing monofunctional acrylic monomer. The composition liquid part may contain a mixture of monofunctional monomer(s) and polyfunctional monomer(s), wherein the polyfunctional monomers comprise between 12 and 22% w/w of the total monomers in the uncured composition. Metallography mounts and processes for producing the mounts are also described.
