FIDIA S.r.l. – Technical Global Services supplies both resins for the installation of advanced composite materials and polyurea, a resin that has revolutionized civil engineering and the structural strengthening industry.
Resins. FIDIA S.r.l. supplies resins that are used for installing in situ advanced composite materials systems; in particular:

• primer is used for the preparation of the substrate on which the composite materials are installed and it is fundamental for a correct performance;
• resins for the in situ impregnation of composite materials, made of either carbon, glass, aramid or steel fibers. Mechanical properties of composites depend on the arrangement of the above-mentioned fibers and the resin used for installation.

The use of such resins for the in situ impregnation of the fibers supplied by FIDIA allows to classify the application as "Type-A applications": according to the CNR-DT 200/2004 guidelines, the producer specifies the mechanical and physical properties of each single element and of the entire system, which represents a complete strengthening systems consisting of fibers, resins, adhesives and other components.

Polyurea. FIDIA S.r.l. pays attention to all new chemical products for the building industry and to the research and development of new composites. The company provides indeed the raw materials and the equipment for the installation of the system. Polyurea is a resin derived from the reaction product of an isocyanate and a resin blend component commonly applied over concrete and steel structural members for corrosion protection and abrasion resistance. Polyurea also has excellent properties thanks to its very fast polymerization (1-3 seconds), high impermeability, extremely large elongation and its high abrasion resistance. It can be applied on any type of surface and geometry, since it can be molded and shaped using hand aerosol pistol that allows the operator reaching any corner.

The advantages of polyurea can be summarized as follows:

• ultimate deformation up to 250-400%;
• great toughness;
• ultimate tensile strength > 15 Mpa;
• excellent bond strength on properly prepared masonry, natural stone, concrete and steel substrates;
• excellent abrasion strength, high resistance to thermal shock and to solvents;
• low permeability;
• no VOC's and little to no odor;
• fire resistant up to class I;
• weather tolerant: cures at -25 °F to >300 °F even in high humidity.
