Paste for insulating between dissimilar metals. Particularly good for stainless steel fittings on alloy spars. 115ml

Uses
Duralac is indispensable for the sealing of joints between dissimilar metals of all types including magnesium and its alloys. It is also valuable for the protection of metals in contact with wood, synthetic resin compositions, leather, rubber, fabrics etc.

When the components of a structure are of different materials, it is essential that the points or faces of contact should be treated with corrosion inhibiting materials because in the presence of electrolytes considerable differences of potential arise, not only where different metals are in contact, but also where components of the same metal under different stresses are in contact: for example as between the aluminium alloy plates or extrusions and rivets or bolts used in building up the structure, in industrial areas where structures are exposed, in flue ducts and acidic vapours.

In close proximity to the sea where a salt-laden atmosphere will be met with, structures will need the maximum attention to prevent corrosion due to the electrolytic cells set up by the salt-laden moisture deposited upon the structure.

Application
Duralac is supplied ready for use and must not be thinned. It is best applied by brush. When Duralac is applied to metal or other surfaces the volatile solvent evaporates and the compound sets to the touch, but remains tacky for a considerable period.

It is important that the joint should be closed while Duralac is still tacky - so that it is in such a condition that it will flow sufficiently under pressure to close the gaps in the joint. It will harden somewhat if a thin film is left exposed to the atmosphere for a long period and this will prevent the making of a close joint.
