Special coatings are considered to be highly specialised activities which require the use of technologically advanced equipment and systems by trained and highly qualified technical and operational personnel.


Vinyl ester and butyl rubbers
Vinyl ester and butyl rubber coatings are used to protect carbon steel alloy components, such as, for example, those used in the manufacture of desulphurisation and denitrification plants, used for containing pollutant fluids.
In both cases, the process cycle includes the preparation of the support by sandblasting, generally to grade SA 2.5 followed by the application of one of more primer coats, depending on the level of corrosion protection required.
In the case of vinyl ester, two or more coats of resin containing glass flake are applied after the primer. If, on the other hand, the application of butyl rubber is chosen, a layer of adhesive is spread on the primer followed by a layer of rubber, which is cut and shaped according to the component to be coated. This is then rolled to eliminate the air bubbles which will inevitably be formed during application. This type of coating may reach thicknesses of 2.5 - 4 millimetres.
The company has gained considerable experience whilst participating in the feasibility studies and setting up of the process cycle for the first desulphurisation plant built in Italy, whilst collaborating with the leading global manufacturers (Fuji Apsa for the vinyl ester activities, Keranchemie SGL HAW for activities regarding the application of butyl rubber).



Anti-reflective coatings
Under particular environmental conditions it is necessary to keep the operating temperatures of certain fluids within preset design values, in order to allow the systems to work efficiently. For this particular requirement, anti-reflective coatings are applied. This involves the cleaning of the components, generally by jet washing, and the subsequent application of a single coat of acrylic resin.



Thick coatings
In order to protect particular structures from the aggressive nature of the surrounding environment, use is generally made of process cycles which include the application of several films of paint, reaching considerable thicknesses. These coatings are mainly applied on steel structures to be installed offshore, such as, for example, wind turbine towers, rather than oil rigs.
