Carbozinc 11 HS - Low VOC Zinc Primer is a high-performance, inorganic zinc-rich primer engineered by Carboline for superior galvanic corrosion protection in industrial, atmospheric, and harsh environments.

This ultra-low VOC primer combines high zinc loading for exceptional cathodic protection, rapid cure, low-temperature application down to 15°F, and compatibility with faying surfaces (Class B slip coefficient), making it ideal for steel structures, tanks, vessels, piping, bridges, and infrastructure requiring long-term corrosion resistance with regulatory VOC compliance.

Key Features:

• Ultra-Low VOC & High Zinc Loading: Provides excellent galvanic protection while meeting stringent VOC regulations; ~84% zinc by weight in dry film for superior cathodic action.
• Rapid Cure & Low-Temp Application: Dry to handle in 1 hour at 75°F; cures down to 15°F for year-round use and fast project turnaround.
• Faying Surface Compatibility: Meets Class B slip co-efficient and creep criteria for bolted connections in structural steel applications.

Common Industry Applications:

• Industrial & Petrochemical: Primer for tanks, vessels, piping, and structures in refineries, plants, and facilities exposed to corrosive atmospheres.
• Infrastructure & Offshore: Structural steel, bridges, platforms, and equipment in harsh marine or coastal environments needing galvanic protection.
• General Maintenance & Heavy-Duty Protection: Steel fabrication, shop priming, and field applications in aggressive conditions requiring low-VOC, high-performance zinc primers.
