is a chromate-free jointing compound designed to inhibit electrolytic
decomposition between dissimilar metals - often called galvanic
Duralac Green is an environmentally friendly
alternative with advanced performance.
Duralac Green has low solubility in water
and will not erode with time; even when subjected to
high pressure from considerable water flow.
Duralac Green enjoys excellent adhesion properties
to most substrates and because of its tough flexible composition, has
very low water absorption.
Duralac Green has a two year shelf life from
the date of despatch when stored below 20°C. Once a container is opened,
the remaining Duralac Green will form a skin.
Duralac Green 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 Green 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 Green 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 Green to inhibit corrosion.
