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 150°F / 66°C, 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 sulfur-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 de-aired clay. The de-airing 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 slightly more dense and better for extrusion processes. In our opinion, the de-airing process will improve the working characteristic of any Industrial Styling Clay that Chavant manufactures.
Handling Tips
CM-70 Hard Styling Clay is most often warmed to its softening point before it is applied to armature. Care should be taken not to burn the clay during warming.
Unique Properties
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.
Specific Gravity
1.6 gm/ml (water = 1.00 gm/ml)
Softening Temperature
150°F / 66°C
Cautions
CM-70 contains sulfur, which may cause a burning sensation in the eyes of some users. Although not dangerous it may be uncomfortable. Over heating sulfur based clay will cause the sulfur to crystallize, which is easy to identify by the small, sand like granules which will be seen after the clay has been burned. These granules are impossible to remove so burned clay should be discarded. Do not overheat / burn the clay.
Hygiene
Wash hands with soap and water after use.
