Carboweld 17 FG is a fast-drying, two-component, ethyl silicate inorganic zinc-rich primer by Carboline for the prefabrication priming of steel in marine, coastal, and demanding industrial environments. It is a weldable, hard, abrasion-resistant primer that delivers excellent cathodic (sacrificial) corrosion protection on blast-cleaned steel.

This high-performance shop primer is specifically formulated to protect steel on marine vessels, offshore structures, and heavy industrial fabrications during construction, cutting, welding, and assembly. It offers superior heat, impact/abrasion resistance, as well as undercutting resistance. Carboweld 17 FG has been tested by DNV and is ABS-certified to the IMO/PSPC standard for ballast tank linings. It is also certified as a pre-construction primer for Lloyd’s Register constructions.

Key Features:

• Weldable Pre-Construction Primer: Allows direct welding over the applied primer with minimal spatter and no need for removal, producing high-integrity welds.
• Cathodic Protection: Provides excellent sacrificial/galvanic corrosion protection during fabrication, storage, and transport.
• High Heat Resistance: Continuous dry temperature resistance to 750°F (399°C); non-continuous to 800°F (427°C).
• Hard, Abrasion & Impact Resistant: Tough film ideal for demanding marine and offshore fabrication environments.
• Excellent Undercutting Resistance & Certifications: ABS-certified to IMO/PSPC for ballast tanks; DNV tested; Lloyd’s Register approved.

Common Industry Applications:

• Marine & Offshore: Prefabrication priming of steel for ships, offshore platforms, ballast tanks, and other marine structures.
• Heavy Industrial Fabrication: Structural steel, beams, plates, and assemblies in coastal or corrosive environments requiring weld-through capability.
• High-Performance Shop Priming: Blast-cleaned steel in controlled shop conditions where fast dry-to-handle, heat resistance, and subsequent topcoating are required.

Carboweld 17 FG is a TWO-COMPONENT SYSTEM (PART A BASE & PART B ACTIVATOR).
