CM-70 Industrial Hard Styling clay is primarily used by product designers for the creation of automotive, marine, aerospace and consumer product models.
Sculptors occasionally use CM-70 for high detail artwork, when a firmer clay body is desired or if they want to incorporate various shapes normally seen in transportation design into the sculpture.
CM-70 is very firm at room temperature and can be shaped with modeling tools or templates. Because of its room temperature firmness CM-70 is suitable for studios with a desire to machine the clay.
Normally warmed to approximately 145° F, a temperature that begins to feel hot in the users hands, CM-70 will accept developed template shapes well at most temperatures.
The surface and corners of CM-70 can be smoothed nicely by hand at room temperature, although the flexibility is greatly reduced at room temperature. It would be difficult to take a cube of CM-70 and roll it into a ball at room temperature.
CM-70 is a sulphur-based product that has excellent qualities of adhesion, cohesion and consistency. It can be carved, extruded and slicked to an extremely smooth surface.
CM-70 is available as a DeAired clay.
The DeAiring process reduces the individual clay compound particle sizes creating a smoother clay and, as the name suggests, entrapped air is removed from the finished clay billet making the clay more slightly more dense and better for extrusion processes.
Handling Tips: CM-70 Hard Styling Clay is most often warmed to its softening point before it is applied to an armature. Care should be taken not to burn the clay during warming.
Unique Prop’s: Hard styling clays can be shaped to a very accurate and stable model. Many types of molds including MDM, polyester, epoxy, urethane and silicone can be taken from the clay surface.
Density: 90 pounds per cubic foot. Softening point: 135° F – 150° F Working Temp: Room Temperature to 145° F.
Cautions: Due to potential oxidation, if a model is expected to sit for months at a time, it may be best to keep it out of direct sunlight and to cover it with a plastic bag to prevent direct contact with air. Wash hands with soap and water after use.
All clay products are available by the case.
