  • Condursal 710
    An extremely effective stop-off paint for all forms of gas carburizing. (NOTE: it is not suitable for carbonitriding.) CONDURSAL 710 is particularly suitable for the deeper case work up to .120" range. Only one coat application is required. This paint can be applied by brushing, dipping. spraying or with the use of pressure gun equipment. Removal of residues after heat treatment is done by blasting or wire brush. CONDURSAL 710 is free of solvents and other harmful material. It will not glaze the inside of your furnace like other competitive stop-offs.

  • Properties
    CONDURSAL 710 is extremely effective as a stop-off paint for all forms of gas carburizing. It is particularly suitable for deep case carburizing up to depths of .120" Only one coating of CONDURSAL 710 is necessary for effective protection against carbon pickup. Therefore it is very economical. Because the residues of CONDURSAL 710 are not soluble in water, alkaline solution or solvents, they must be removed after heat treating by blasting or wire brushing. CONDURSAL 710 is free of any solvents, which is important in respect of health and safety regulations.
  • Condursal 710, paste consistency
    This consistency is best suited for use with a dispensing gun, which applies the paste from a pressurized container. (Similar to grease gun equipment) This method of application can be easily mechanized for mass production - as recently shown in fully computerized installations at FORD and GM plants. It provides sharply defined layers with maximum efficiency and is particularly suited for the protection of external threads, short gear teeth, splines, etc.
  • Condursal 710 for spraying
    In this case the rather liquid paint is applied using a pressurized container combined with spraying pistols, the nozzles of which normally have a diameter of .060 - .100". Spraying is most commonly used for continuous work, e.g., large series of pieces such as gears and axles.
  • Condursal 710 for immersion
    This grade is best suited for components with the area to be protected located at one end, so that coating by dipping is possible. Its consistency adheres quickly and does not tend to drip off. It is recommended that the excessive paste at the bottom of the work piece be removed by shaking or wiping so that it can be recovered. As long as the paste is not fully dry it may be reconditioned by simply adding small quantities of the "Special Thinner for Condursal 710". When dipping the parts, it is useful to move the piece around to prevent air bubbles from sticking to the surface.
  • Condursal 710 for painting
    This "normal" consistency is most commonly used for manual application, whenever the variety of work pieces or areas to be coated do not allow automatic or mechanized coating. Application of this paint is similar to oil based paint using a flat soft bristle brush.
