Discuss what attributes might make a resin inappropriate for use as a hot-melt casting resin
What will be an ideal response?
If the viscosity of the melted resin were too high, the melt may not flow without external pressure and, therefore, would not work well as a hot-melt casting resin. Another problem could arise if the resin degraded easily at the temperatures required to keep the material liquid.
