Copaltite Usage Guide Safety Data Sheet (SDS)

Copaltite General Directions For Use

  • A thin coat of Copaltite should be applied both surfaces to be sealed. The surfaces should be clean and dry. All dirt, oil, grease or moisture should be removed with gasoline or other solvent before applying Copaltite, as it has no affinity to foreign matter and must secure a direct bond to the metal surface.
  • Heat of at least 212°F must be applied to set Copaltite. At this temperature, set up time could take up to 4 hours.  At 300°F, set up time is approximately 30 minutes. 
  • If a joint is to hold high pressure at an elevated temperature, heat should be applied without pressure until the Copaltite has set.
  • If using Copaltite for a steam application, apply it to the joint, tighten and heat the joint by turning on the steam at little or no pressure for about six hours, preferably overnight. The Copaltite sealed joint will then withstand high temperatures and pressures.
  • If Copaltite has hardened, a wire brush and alcohol may be used to remove the product.
  • If Copaltite needs to be thinned, Copaltite liquid can be used to thin Copaltite Cement. To thin Copaltite liquid, pure alcohol can be used.
  • Copaltite should be stored in a cool, dry place. The shelf life is one year from date of manufacture when stored at 72°F.

Instructions for sealing turbine horizontal joints

  • After casing has been lifted, clean upper and lower flange surface of all foreign matter. Be sure surface area is clear, dry, and free of any oil. Use gasoline or any solvent to clean off surface. Wipe clean and dry.
    • Grooved turbines with smooth surface flanges
      • Apply a thin film of liquid Copaltite to upper and lower flange surfaces, but not in the grooves. Allow the material to become tacky, then lower the casing and bolt down. This will make an actual tight joint without considering grooves.
      • While the turbine is being warmed up before being placed in operation, and while turbine is hot, a pressure gun capable of producing at least 4000 psi should be used for dispensing Copaltite cement into the grooves. Filling the grooves should be done around the entire turbine in order to secure a uniform and permanent joint. This forms a Copaltite cement key.
      • When dispensing Copaltite cement into any one groove outlet, remove the nest plug (which we will call No. 1) in the direction the groove is being pumped. When the Copaltite begins to flow from No. 1 opening, close same and also remove gun and close opening. Start pumping into the next opening (which we will call No. 2), at the same time removing plug from No. 3 opening. Continue until all plugged openings have been pumped.
    • Grooved turbines with scored surfaces flanges
      • In the event the flange surfaces are scored, then substitute Copaltite cement in the place of Copaltite liquid for making flange joint. Use Copaltite cement for pumping groove.
