F-118 F 28 is a pattern wax containing 28% filler material. Although it is a filled wax, the pattern's surface remains even and light. Further, as the viscosity of the wax in its liquid state is very low, there is no mold cracking because of de-waxing. This wax is strong is best suited for automatic pattern making for small investment casting products such as machine and automobile parts.
