Copaltite Directions for Use

  • For best results, a very thin coat of Copaltite should be applied. Normally, Copaltite liquid gives sufficient coverage for a perfect seal. However, if surfaces are rough or scored, Copaltite cement can be used.
  • Surfaces must be clean and dry. Gasoline or other solvents should be used to remove dirt, grease, and moisture. Apply Copaltite by coating both surfaces lightly. The joint may then be closed and tightened.
  • Heat will accelerate the setting up of Copaltite.
  • When the joint is to hold high pressure at elevated temperatures, heat should be applied without pressure until the Copaltite is set up. Above 300° F set up requires about 15 minutes – lower temperatures up to 4 hours.
  • To remake joints, hardened Copaltite should be removed with a wire brush and alcohol, and fresh Copaltite applied.
  • Storage – It is advisable to store Copaltite in a cool place away from heat or sunlight. In the event that a can is opened repeatedly, Copaltite will thicken slightly and thinning may be desired. Shelf life: one year from date of manufacture, at 72° F.
  • Thinner – For thinning Copaltite Cement, Copaltite Liquid should be used. To thin Copaltite Liquid, pure alcohol should be used. In no case should turpentine or other thinner be added.
  • Copaltite Liquid – A thin, easily spreadable material for use on threaded joints and most machined surfaces.
  • Copaltite Cement – Paste-like adhesive for rough or scored surfaces.
  • Copaltite Liquid and Copaltite Cement are available in quart cans (2.2 lbs. net) and 5 oz. collapsible tubes.
