Liquid Colloidal Graphite
Colloidal Graphite is a contact indicator for the laboratory technician.
It is ideal for fitting together castings and telescopic castings. Liquid Colloidal graphite is water soluble.
It is also an excellent anti-flux agent. Solder and cast metal may be controlled by painting strips of Liquid Colloidal Graphite in areas where you do not want solder or cast metal to adhere.
To prevent flash metal from adhering to threaded components–or any area you do not want cast metal to adhere to– paint a thin coat of Colloidal Graphite
In this case, paint Graphite on the threads to prevent flash from adhering to the threads. Let the Colloidal Graphite fully dry before investing and casting.
