Overview
This document from HIANSA PANEL S.A. provides a technical guide for selecting acceptable coatings for exterior building applications such as cladding, roofing, and accessories. It outlines coating types, their performance characteristics, and environmental suitability, referencing Arcelor Mittal technical specifications and warranty conditions.

1. Coating Types and Specifications

The guide lists various coatings including Standard, Granite, HD, HDS, PVDF, and HDX, each with different performance levels. Key parameters include:

• Surface hardness (pencil hardness scale)
• Gloss level (Gardner 60º)
• Condensation resistance
• Corrosion resistance category
• Salt spray test duration (hours)
• Coating thickness (microns)
• UV resistance category

Some coatings are available in multiple thicknesses (e.g., 35, 45, 60 microns). The document notes that coatings are subject to Arcelor Mittal technical specifications and that HIANSA PANEL reserves the right to modify the document without notice.

2. Environmental Application Categories

The guide classifies environments into categories based on pollution, humidity, and proximity to the sea, which influence coating selection:

• Moderate environments: Rural, low pollution, low to medium humidity
• Aggressive environments: Urban and industrial areas with moderate to severe pollution
• Marine environments: Coastal zones at varying distances from the sea (less than 3 km, 3-20 km), including direct sea spray zones
• Special environments: High UV radiation areas (altitudes above 900 m or specific geographic zones), and environments with additional stress factors such as abrasion, high temperature, humidity, dust, or sea spray

3. Environmental Definitions and Recommendations

The annex defines environmental categories in detail:

• Rural environment: Areas with no specific pollution except minor sulfurous vapors from heating.
• Urban/industrial moderate: Areas with slight atmospheric pollution from factories but no high chemical corrosion risk.
• Urban/industrial severe: Areas with high chemical pollution from sources like incinerators, cement plants, paper mills causing significant corrosion risk.
• Marine environments: Zones defined by distance from the coast, with special notes on direct sea spray exposure and mixed environments combining marine and industrial factors.
• Special environments: High UV radiation zones and those with additional environmental stresses.

4. Performance and Usage Notes

• Coatings like Granite HDX are suitable for harsher marine environments, including areas up to 300 meters from the sea, excluding direct seawater attack.
• Coatings differ in UV stability, corrosion resistance, and mechanical robustness, influencing their suitability for specific environments.
• HIANSA PANEL disclaims responsibility for improper coating application or use outside the specified guidelines.

5. Critical Recommendations and Limitations

• For distances to the sea less than 300 meters, consultation with the technical department is mandatory.
• Nominal gloss values comply with EN 10169 tolerances.
• Automatic warranty coverage depends on the coating and environment; technical consultation is advised.
• The document is subject to change without prior notice.
