Summary:
The range of potential applications for adhesives technology has been considerably
widened with the recent advent of these new synthetic resins. Until the 1980’s
it was not possible to apply epoxy resin compositions underwater to form strong
and durable joints.But now products have been produced which may be used underwater
and have become significant engineering materials for the Marine Industry, Dock
and Harbour Boards and,and for the Offshore Oil Industry.
THE WRA UNDERWATER SYSTEMS
Epoxy based adhesives are preferred for underwater jointing because of the ease
with which they can be cold cured, their good adhesion and their general convenience.
Specifically developed for underwater use, this WRA series of epoxy adhesives
is tolerant of some contamination, although
best results are obtained on well-prepared surfaces- ideally, grit blasted or
mechanically abraded and free from any oil and/or grease. However, in an emergency,
it will not always be possible to make ideal surface preparations and, in such
cases, the effectiveness and/or durability of the bond to the substrate will
be impaired, although the results may still be acceptable especially for temporary
repair. Decisions regarding surface preparation must be taken on site, dependent
upon the situation in hand.
