Plascoat has been involved in major
construction projects around the world where a highly durable, long lasting and resilient
finish is among the criteria for the specifying architects – along with, of course,
the requirement for superior corrosion protection for the base metal. Traditional coating
materials such as EVA and Polyamides have, on many occasions, failed to live up to the
expectations in countries that put coatings to a stern test.
Projects like the footbridge in Angora near
San Sebastian in Northern Spain required a new type of coating as, after only a few
months, the polyamide coating began to peel from the sections. The search was on for a
coating that could accommodate the wide temperature range, provide a high level of UV
resistance, meet the requirements of a tightening budget, and offer a coating life in
excess of 10 years.
Plascoat PPA 571 was the answer with its
high level of durability and weatherability and long term adhesion to both steel and
aluminium. Regular inspections of this project indicate that the lifetime criteria of 10
years will be easily surpassed. Indeed after 7 years the coating still retains the same
gloss and colour and mechanical properties and still looks like new. Another project where Plascoat were called
upon to provide a solution involved the Paris based engineers, Freyssinet, who were
managing a project to construct the Colindres Viaduct. After only six months the previous
coating had deteriorated and started to peel off under the effects of UV rays, salt
attack, and extreme temperatures. Once again, therefore it was the harsh climate that
would be the principal reason PPA 571 was chosen.
Since re-coating all of these parts in PPA
571(around 650, 3 metre, 200-300 diameter tubes – nearly 2 km in all) the effects of
the worst of the Spanish weather, salt and traffic pollutants have failed to take the
gloss off Plascoat PPA 571.
