How thick should Copaltite be applied when used as a gasket coating?
A thin film of Copaltite should be applied when used as a gasket coating. The Copaltite should be applied to both surfaces of the gasket and allowed to become quite tacky before tightening down the surfaces.
How thick should Copaltite be applied without a gasket?
A thin film of Copaltite should be applied when used as a gasket coating. The Copaltite should be applied to both surfaces of the gasket and allowed to become quite tacky before tightening down the surfaces.
Should the joint be made up tightly while the material is still moist or should it be permitted to dry?
The joint should not be tightened down immediately. Sufficient time should be given for the thinner content to evaporate. This will not only insure a better joint but will keep the Copaltite from being forced out when the joint is tightened.
If Copaltite is used on flanges, should both faces be coated?
Yes, both faces of the flange should receive a very thin coat of Copaltite.
Will Copaltite freeze a joint after being in service for a long period of time?
No, Copaltite will remain plastic indefinitely, and all joints are easily broken with alcohol and a wire brush.
Will a wide range of temperature cause Copaltite to become hard and brittle?
Copaltite will remain plastic under any conditions with temperatures varying from -315°F to 1500°F.
When storing Copaltite, should any special precautions be taken?
It is important to store in a cool place away from heat or sunlight. In the event that a can is opened repeatedly and a small is used, it is advisable to keep a thin film of methanol (pure alcohol) on top. This will prevent Copaltite from drying out when coming in contact with the atmosphere.
How should the surface be prepared for Copaltite application?
All dirt, oil, grease or moisture should be carefully removed with gasoline before applying Copaltite, as it has no affinity for foreign matter and must secure a direct bond to the metal surface.
Will extreme vibration, contraction or expansion impair the security of the joint?
No, the plastic quality of Copaltite prevents any cracking or breaking due to extreme vibration, contraction or expansion.
In the event that it is necessary to thin Copaltite, what should be used?
For thinning Copaltite cement, Copaltite liquid should be used without exception. To thin Copaltite liquid, pure methanol should be used. In no case should turpentine or other thinner be used.
How should heat be applied?
Externally applied heat can be accomplished with a heat gun, infrared lights, or an oven for small parts. Care should be taken if an open flame such as a torch is used because Copaltite is flammable. If the metal is heated at a remote distance from the Copaltite joint, the metal can be made to conduct heat to the joint and affect a cure.
Are there any special instructions for using Copaltite on large diameter flanges?
Cover both faces with Copaltite cement of minimum thickness, after which bring the faces into contact but do not tighten the joint for approximately one hour. Additional security may be obtained by slotting both inside flange faces – the slot to be staggered.
How do I know how much Copaltite I need for my application?
