Epofix is a cold-setting resin based on two fluid epoxy components. Epofix is specially developed for mounting of irregularly shaped specimens and for impregnation of porous specimens, where low shrinkage and good mechanical properties in the cured state are required. Owning to its low viscosity, Epofix will penetrate into all porosities and cracks of the specimens. After curing, Epofix can be cut, ground, polished, grilled, etc.
Included in the Epofix kit are syringes for measuring out suitably small quantities of resin (20 ml syringe) and hardener (5 ml syringe)
An excessive quantity of hardener will promote the reaction. This reduces the processing time, but involves the risk that the mold may melt or that the specimen will become overheated.
Where considerable amounts of Epofix are used, the polymerization temperature may rise to such a level that it is necessary to eliminate the heat generated.
For mounting of irregularly shaped specimens and, especially, for impregnation purposes heating of the Epofix mixture to 50°C is recommended before pouring it over the specimen. This gives the mixture a lower viscosity, thus ensuring a more through penetration into the pores of the specimens.
For porosity measurements, or to obtain a contrast, Epofix can be colored by adding Epoxy-Dye to the resin before mixing.
