It is often favoured for embedding individual samples, when the acquisition of a mounting press is not economically justifiable. Conversely, it is helpful for mounting large numbers of samples as quickly as possible. Cold mounting products fall into one of three categories: acrylics, polyesters and epoxies. They may consist of two or more components that need to be mixed together to make a solid cured specimen. Epoxide compounds exhibit the lowest contraction. The long curing time gives outstanding edge retention and very low shrinkage, and is chemically resistant. Acrylics have a short curing time and have a small amount of contraction that can be improved with fillers and curing under pressure in a pressure vessel. With polyester resins the curing times are relatively short, but often produce a poor quality mount and are only used due to low cost. After mixing the components, the hardening process takes place via an exothermic reaction. During curing, particularly with acrylics, this hardening process can generate over 80°C, and one must be careful when working with temperature-sensitive materials, e.g. plastics, where the structure of the sample can be affected. Vacuum Impregnation: Porous materials, e.g. ceramic(s) or sprayed coatings should be vacuum impregnated with epoxy resin prior to sectioning. The porous or friable ceramic is strengthened and protected by the epoxy resin. Cavities, pores and cracks that are open to the surface are filled with the embedding material. For high contrast definition of pores and cracks, we offer Epo-Color resin which, under dark field lighting, appears a vivid red colour and thus makes the interpretation of the structure easier.
