Epoxy Resins

BIODUR® E 12 (EP12)
Epoxy resin of medium viscosity; translucent, firm, slightly flexible when cured. Choose from different hardeners to vary the properties of the specimens:

 
E 12 with E 1
Standard epoxy resin for sheet plastination. For especially good staining of specimens.

 
E 12 with E 6
For preparing histological sections to be sawed, milled, or ground. The cured polymer becomes very firm and cannot be separated from the glass.

 
E 12 with E 7
For preparing histological sections to be sawed, milled, or ground. The cured polymer becomes very firm and cannot be separated from the glass.

E 12 will partially crystallize after only a few days, especially when stored cool. Heat to +50°C to +70°C (+120°F to +160°F) prior to use. It is advisable to order E 12 in buckets of a size compatible with the available heating cabinets.

BIODUR® E 20 (EP20 – EP22)
Capillary-passable epoxy resin for color contrast presentation of vessels in plastination and for the manufacturing of corrosion specimens. E 20 is characterized by great firmness and a low (<2%) inclination to shrink, is resistant to acetone and can withstand methylene chloride for short periods of time (< 24 h). The processing properties and the flexibility of the cured resin can be varied to a large degree through the use of appropriate additives (➔ Additives, Plasticizers or Organic Solvents) Available in red (EP21), blue (EP22) or clear (EP20).
