J-525 Industrial Hard Styling clay is primarily used by product designers for the creation of automotive, marine, aerospace and consumer product models. Sculptors occasionally use J-525 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.
J-525 is recognized as a worldwide industry standard. It has a medium firmness at room temperature and can be shaped with modeling tools or templates. Because of its room temperature firmness J-525 is suitable for studios with a desire to machine the clay.
Normally warmed to approximately 145°F / 63°C, a temperature that begins to feel hot in the users hands, J-525 will accept developed template shapes well at most temperatures. The surface and corners of J-525 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 J-525 and roll it into a ball at room temperature. J-525 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.
J-525 is available as a de-aired clay. De-aired J-525 is one of Chavant's most popular products. 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.
