Cold mounting requires no pressure and little heat, and is a means of mounting large numbers of specimens more rapidly than by compression mounting.
Materials for cold mounting are classified as polyesters, epoxides and acrylics.
Polyesters are transparent and usually water clear;
Epoxides are almost transparent and straw color;
Acrylics are opaque.
Cold mounting materials of all three classifications are two component systems that consist of resin and a hardener; both the resin and the hardener can be liquid, both can be solids, or one can be liquid and the other a solid.
Mixing of the resin and the hardener produces exothermic polymerization, and therefore this operation is crytical in producing a satisfactory cure and limiting the temperature to a permissible level. The temperature rise may reduced at the expense of longer curing time.
