Epoxy Resin Casting; Aluminium Filled

Advantages

Highest oxygen index, good thermal conductivity, low mould shrinkage and density compared with other modified casting epoxy resins.

Disadvantages

Presence of aluminium fillers can sometimes inhibit cure. No resistance to acids. Lowest tensile strength, flexural modulus and notched impact strength and highest linear expansion compared with other modified casting epoxy resins.
