Carboweld 14 WB is a fast-drying, high-zinc content, two-package water-based inorganic zinc-rich pre-construction primer engineered by Carboline for superior temporary corrosion protection on steel substrates with weld-through capability.

This environmentally compliant, low-VOC primer delivers excellent galvanic protection during fabrication, storage, and transport, featuring ultra-high zinc loading, rapid dry to handle times, and compatibility with welding operations, producing high quality welds without primer removal. Ideal as a shop/yard holding primer for structural steel, where fast turnaround and minimal preparation are essential.

Key Features:

• Ultra-High Zinc Content & Galvanic Protection: Provides cathodic (sacrificial) corrosion protection similar to hot-dip galvanizing during construction.
• Weld-Through Capability: Allows direct welding over the applied primer with minimal spatter and no need for removal, ensuring sound, high-integrity welds.
• Fast Drying & Low VOC Water-Based: Quick dry-to-handle for efficient shop production; environmentally friendly with low odor and compliance to strict VOC regulations.
• Excellent Shop Primer Performance: Superior holding properties during fabrication, storage, and transport; compatible with subsequent topcoats in full coating systems.

Common Industry Applications:

• Steel Fabrication & Structural Steel: Beams, columns, plates, and assemblies in fabrication shops requiring temporary protection and weldability.
• Pre-Construction & Shop Priming: Used on blast-cleaned steel during manufacturing, cutting, welding, and assembly stages to prevent flash rusting.
• Heavy Industrial & Infrastructure Projects: Bridges, buildings, offshore platforms, and other steel structures where primer is applied in controlled shop conditions before field erection and final coating.

Carboweld 14 WB is a TWO-COMPONENT SYSTEM (PART A & SPECIAL ZINC FILLER).
