UNIQUE TECHNOLOGY

Protecting both steel and concrete, Euronavy achieved a level of excellency thanks to its Research & Development commitment. Ultimately, this innovation capacity enabled us to present also a portfolio of underwater applicable products.

STEEL

ES301 priming: humidity tolerance during curing.

An important part of Euronavy’s solutions for steel protection are based on a unique, internally developed solvent-free epoxy technology (EURO-basic ES301 products). This technology has enabled us to offer a unique solution, putting together high protection (solvent-free hard coating, edge-retentive behavior) and tolerance (no dew-point restrictions, may be applied over damp surfaces, surface tolerance to adhered rust). These features are now offered by ES301, together with good film flexibility and user-friendly properties as extended pot-life. The edge-retentive behavior of ES301S version assures a good film thickness over edges, corners and welding seems (> 70% compared with flat surfaces, improving on the norm of less than 30% when using conventional solvent based coatings).

CONCRETE

Euronavy products are widely used for industrial and decorative flooring.

The expertise of Euronavy developing solvent-free epoxies was exported to other markets as concrete protection. As ES301 for steel protection, Euronavy also offers a solvent-free epoxy primer for humid concrete: the EURO-wet BE14. Solvent-free epoxy portfolio for concrete includes special finish for different kinds of substrate aggression, flooring solutions (self-leveling coatings, epoxy resins mortars, high thickness coatings, etc), injection resins, and special resins for glass fiber lamination, expansion joints or special repairs.

Concrete coating on Water Treatment Plants: a major use of Euronavy solutions.	Pulp & Paper industry, Water Treatment Sedimentation Reservoir: a very aggressive media that Euronavy coatings can face with full success.
Using BE14 (solvent-free epoxy primer tolerant to humidity) makes hydroblasting possible, allowing higher surface cleaning quality and lower cost because abrasive blasting can be avoid.	Solvent-free epoxy special resins from Euronavy are being used in major concrete repair jobs (concrete dams, tunnels, etc).

UNDERWATER APPLICATIONS

Euronavy-developed technology making possible the humidity tolerance of some of our protective coatings was also used to create an underwater-applicable range of products, from primers to anti-fouling, including also special resins for underwater injection and repair.

ES301 TECHNOLOGY

The EURO-basic ES301 is an ecologically engineered coating hailed by marine and industry leaders as a major breakthrough. The US Navy praises ES-301 as one of the best primers for hydroblasted surfaces. ES-301 is a solvent-free two-part kit modified epoxy coating with excellent anticorrosive power that can be applied over damp steel surfaces without Dew Point restrictions. We believe that ES-301 currently represents not only the best solution as a primer coat after hydroblasting, but also an excellent tolerant system for a wide range of applications, including demanding ballast tank protection, marine and off-shore new building, converting or maintenance, steel bridges coating or industrial maintenance on harsh environments as refineries, combustible tank farms, pulp & paper and others.

ES301 distinctive features:

Product Features Modified epoxy, polyamine cured Solvent free Tolerant to damp surfaces No dew point restrictions Tolerance to adherent iron oxides High compatibility with old coatings Very high adhesion to steel (> 170 Kg/cm2) Reacts with steel, oxides and moisture Steel roughness is not a critical factor “edge retentive” version (ES301 S) available. Friendly pot-life (up to 3 hours at 25ºC) Applicable by brush, roll or airless (60:1) with adequate viscosity.

System Characteristics Surface preparation standard: hydroblasting to SSPC SP12 Wj2 (Wj2-M visual standard as per SSPC Vis4 – NACE Nº7, MEDIUM flash rust) Typical DFT per coat: 100 – 150 microns Same product for priming / intermediate / finish If UV resistance is needed, the system may include a classic polyurethane topcoat 2 or 3 coat systems, ranging from 200 to 450 microns total DFT, depending on the areas to be protected, corrosiveness and service life target. Comfortable recoating window (16 h – 1 week at 25ºC) No need for dehumidification in enclosed spaces such as tanks and voids.

Advantages of Euronavy’s ES301 technology: answering new needs

HYDROBLASTING + ES301 SYSTEM
PERFORMANCE	Coating immediately after hydroblasting or washing, without the need for drying, assures the lowest possible salt level; Edge retentive intermediate/finish is an additional factor of success; Very high adhesion contributes to increased performance; The absence of dew-point restrictions and the surface preparation tolerance makes it possible to achieve good performance under offshore environment; The solvent-free nature eliminates the risk of solvent retention. This issue is particularly important if heavy pitted steel is the case; The good rheology avoids potentially dangerous over-thickness.
ENVIRONMENT	Solvent free coating; Because the use of hydroblasting is no longer detrimental to the quality of the protection if using this system, this environment-friendly surface preparation method is not only possible but also preferable.
COST	Lower overall cost of hydroblasting + coating is possible, depending on the situation, for the same protection quality level; Saves related costs: no abrasive removal and treatment cost, no need for dehumidification in enclosed spaces; Save time: no need to stop hydroblasting or coating application under humid conditions. The number of stripe coats can be reduced if using the edge retentive version.
SAFETY	Lower flammability risk, both during application and for the paint stock, due to the solvent-free nature of the system; Lower impact on human health: no abrasive dust, no solvents.
