Product Overview

Nitocote AP35 is a solvent-based penetrating primer from Fosroc formulated as the first coat in protective coating systems for concrete in aggressive environments — coastal, industrial, marine, and heavily polluted urban atmospheres where the rate of carbonation and chloride penetration is accelerated. The primer penetrates into the prepared concrete surface, consolidates the near-surface zone, and provides a key for the subsequent barrier topcoat in the Fosroc protective coating system. The solvent-borne chemistry of Nitocote AP35 gives it low viscosity and high penetration into the concrete pore structure, which is important on concrete that is slightly porous or has a higher moisture content — the solvent carrier evaporates without being affected by substrate moisture in the way that water-borne primers can be. Once cured, Nitocote AP35 provides a clear, non-film-forming penetrating consolidant in the concrete that primes the surface for the application of elastomeric or rigid barrier topcoats such as Dekguard W, Dekguard S, Nitocote EP405, or other Fosroc protective coatings. The combined system of penetrating primer plus elastomeric or barrier topcoat provides a comprehensive anti-carbonation and chloride-barrier coating system suitable for bridge structures, coastal buildings, marine infrastructure, and industrial concrete in aggressive chemical environments. Space Arc Engineering distributes Nitocote AP35 for bridge coating, marine structure protection, and industrial concrete maintenance projects across Delhi NCR and Northern India.

Applications

• Penetrating primer for concrete before Dekguard anti-carbonation topcoat
• Consolidating primer for porous or powdery concrete surfaces before coating
• First coat in the Nitocote chemical resistant coating system
• Bridge and infrastructure concrete priming in coastal and aggressive environments
• Marine concrete structure primer in spray zone and tidal zone environments
• Industrial concrete priming before heavy-duty chemical resistant topcoat

Key Advantages

• Solvent-based for deep penetration into porous concrete substrates
• Consolidates weak near-surface concrete before topcoat application
• Compatible primer for Dekguard W, Dekguard S, and Nitocote EP405 systems
• Provides key for subsequent elastomeric and rigid barrier coatings
• Effective on slightly damp concrete where water-based primers may not bond
• Designed for aggressive coastal, marine, and industrial environments
