ISO 9001:2015 Certified

Marine & Offshore Coating Solutions

Engineered for extreme environments. High-durability **C5-M anticorrosion systems** compliant with ISO 12944 for offshore platforms and maritime vessels.

Extreme Environment Challenges
& Technical Standards

Our coating solutions are engineered to exceed **ISO 12944-9** standards, specifically optimized for **CX (Extreme)** corrosivity categories in offshore and marine infrastructures.

C5-M & CX Protection

Unmatched salt spray resistance. Tested for over 1440 hours to ensure long-term integrity of steel structures in high-salinity zones.

ISO 12944 Compliance

Splash Zone Endurance

Designed for the "Wet & Dry" cycle. High-build coatings that withstand mechanical impact and severe wave action on offshore platforms.

NORSOK M-501 Ready

Extreme UV Stability

Advanced topcoat technology preventing chalking and gloss loss under intense maritime solar radiation. Guaranteed color retention.

Weathering Tested
High-performance offshore corrosion protection system featuring Epoxy Zinc-Rich primer, MIO barrier layer, and UV-resistant Polyurethane topcoat for extreme maritime environments.

Typical CX-Level Marine Coating System

Step 01: Primer Layer

Provides superior cathodic protection for steel substrates. Tested for high-salinity marine atmospheres.

DFT: 60-80μm
ASTM D522 Compliant
Step 02: Intermediate Layer

Forms a “shingle-like” barrier against moisture and oxygen penetration. Enhances total system thickness.

DFT: 100-150μm
Barrier Effect
Step 03: Topcoat Layer

Excellent UV resistance and color retention. Protects the entire system from chemical and weather degradation.

DFT: 50-70μm
RAL Colors Available
