Key Features:

• Outstanding Moisture Tolerance: Applies effectively on damp or wet surfaces; continues to cure even underwater for reliable performance in challenging conditions.
• High Build & Low VOC: High solids (low VOC) formulation achieves up to 16 mils dry film thickness in a single coat for excellent barrier protection and efficiency.
• Low Temperature Cure: Cures reliably down to 20°F (-7°C), enabling year-round application in cold climates with fast cure response for quick return to service.
• Surface Tolerant & Versatile: Excellent adhesion and wetting on minimally prepared surfaces; suitable for immersion in salt water, process water (non-potable), and wastewater.

Common Industry Applications:

• Water & Wastewater Infrastructure: Immersion service in wastewater treatment, clarifiers, pipes, tanks, and structures exposed to corrosive water environments.
• Industrial & Marine Environments: Structural steel, piping, tankage, equipment, pilings, and offshore structures in industrial plants, marine settings, and saltwater exposure.
• Under Insulation & General Protection: Coatings under insulation (CUI prevention) up to 300°F; maintenance and new construction in facilities requiring moisture-tolerant, fast-cure protection.
