F-145 F 28 is a pattern wax containing 28% filler material. Although it is a filled wax, the Surface of the Pattern remains shiny and light. In addition, because of the very low viscosity of the wax in its liquid state, there is no mold cracking due to de-waxing. This wax has a relatively large contraction range and is thus suited to automatic pattern making with the use of extrusion machines.
