Duralac is a highly effective jointing compound which prevents electrolytic corrosion between dissimilar metals typically stainless fitting on an aluminium mast or boom.

Ideal for mast fittings, winches, aerials, batteries, bolts, screws, rivets etc.

Used in the aerospace industry as an essential corrosion inhibiting material wherever dissimilar metals are joined.

Duralac has low solubility in water and will not erode

with time, even when subjected to high pressure from

considerable water flow. Duralac enjoys excellent

adhesion properties to most substrates and because

of its tough flexible composition, has very low water

absorption. Duralac has a two year shelf life from the

date of despatch when stored below 20°C. Once a

container is opened, the remaining Duralac will form

a skin.


Duralac is indispensable for the sealing of joints between

dissimilar metals of all types, including magnesium and

its alloys. Consideration should also be given to galvanic

corrosion of the same metal where the electrolyte varies

in concentration forming a concentration cell. Duralac

has excellent protection properties for metals in contact

with wood, synthetic resin composition, leather, rubber,

fabrics etc. When components of a structure are of

different materials, it is essential the ‘points or faces’ of

contact be treated with Duralac to inhibit corrosion in the

presence of an electrolyte where considerable differences

in potential arise. Components of the same metal in

contact with one another under different stresses will also

benefit from the use of Duralac to inhibit corrosion.


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

to ensure 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.
