Epoxy Resin; Flexible

Aug 14 2001

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.
