Epoxy MC; Mineral Filled

Advantages

Lowest cost, lower mould shrinkage and higher elongation at break compared with other glass filled epoxy mouldings compounds. Generally better surface finish compared to cast epoxy components.

Disadvantages

Tendency to stick in mould. Lowest tensile strength and flexural modulus compared with other epoxy moulding compounds.
