Advantages |
| High thermal shock resistance and peel strength, superior elongation at break and significantly improved notched impact strength when compared with general purpose epoxy resin. |
Disadvantages |
| Colour of castings may change with time. Tensile strength, HDT and flexural modulus lower than for general purpose epoxy resin. |
