Product Overview

MC-Dur 2000 is a two-component solvent-free epoxy protective coating from MC-Bauchemie for concrete and structural steel surfaces requiring a high-performance chemical barrier in aggressive industrial service environments. The product addresses the significant gap between standard decorative or architectural coatings (which provide cosmetic protection only) and specialist heavy-duty coatings (which require specialist spray application) — MC-Dur 2000 is formulated for professional roller and brush application at 300 to 500 microns dry film thickness per coat, making it accessible to the standard industrial painting contractor workforce in India without specialist airless spray equipment while still providing chemical resistance to dilute acids (pH 3 to 11), alkalis, petroleum oils, aliphatic solvents, and abrasion. The epoxy chemistry of MC-Dur 2000 (bisphenol A epoxy resin with amine hardener, Component B) provides the dense cross-linked polymer network responsible for the high chemical resistance and very low water vapour transmission rate — properties that make MC-Dur 2000 suitable as both a concrete surface protection coating under EN 1504-2 and a anti-corrosion primer for steel surfaces in C3 to C4 atmospheric corrosivity categories per ISO 12944. In the Indian industrial context, MC-Dur 2000 is particularly relevant for protecting concrete in wastewater treatment plants (biogenic sulphuric acid corrosion risk in anaerobic zones), pharmaceutical manufacturing facilities (repeated cleaning with caustic and disinfectant solutions), food processing plants (acids, fats, cleaning chemicals), and industrial floor areas subject to forklift and heavy vehicle abrasion and chemical spillage from production processes. Space Arc Engineering supplies MC-Dur 2000 for industrial protection projects in Ghaziabad, Noida, Greater Noida, Delhi, and Uttar Pradesh.

Applications

• Concrete surface protection in wastewater treatment and sewage infrastructure — application to concrete walls, floors, and channel linings in wastewater treatment plants, sewage pumping stations, and anaerobic digester structures in Delhi NCR, Noida, and Uttar Pradesh where concrete is exposed to biogenic sulphuric acid (H2SO4 produced by Thiobacillus bacteria oxidising hydrogen sulphide from anaerobic sewage) — the primary cause of accelerated concrete corrosion in sewer and WTP structures; MC-Dur 2000 creates an impermeable barrier that prevents the biogenic acid from reaching the concrete substrate, protecting structures that would otherwise require concrete replacement within 10 to 15 years of commissioning; the chemical resistance of the cured epoxy film to dilute sulphuric acid (up to 10 percent concentration) and to the microbiological exposure in WTP environments makes MC-Dur 2000 a standard material in municipal and industrial WTP concrete protection specifications
• Industrial floor coating in pharmaceutical, food processing, and chemical manufacturing plants — application to concrete floor slabs in pharmaceutical manufacturing facilities, food and beverage processing areas, chemical mixing and storage areas, and battery manufacturing plants in industrial estates in Ghaziabad UPSIDC, Noida Phase 1 and Phase 2, and Hapur Road industrial area where the floor is subject to repeated chemical spillage, concentrated cleaning and disinfection with caustic (NaOH, KOH), acid (HNO3, H3PO4 for CIP cleaning), and disinfectant (sodium hypochlorite, quaternary ammonium) solutions in addition to the abrasion from foot traffic, trolleys, and fork-lift truck movement; MC-Dur 2000 at 2 to 3 coat application (total DFT 600 to 900 microns) provides the required combination of chemical resistance and mechanical abrasion resistance for these high-demand industrial floor environments
• Anti-corrosion primer and intermediate coat for structural steel in C3 to C4 environments — application as a high-build anti-corrosion primer coat (75 to 125 microns DFT) or high-build intermediate coat (150 to 250 microns DFT) on abrasive blast cleaned (Sa 2.5) structural steel in industrial buildings, steel storage tanks, steel support structures for chemical pipework, and equipment supports in moderately aggressive (C3) and aggressive (C4) industrial atmospheric corrosivity categories per ISO 12944; MC-Dur 2000 on steel provides cathodic barrier protection by blocking moisture and oxygen access to the steel surface — the two primary prerequisites for electrochemical steel corrosion; the epoxy primer bonds well to blast-cleaned steel and provides an excellent base for subsequent coats in a total paint system
• Concrete protection in pharmaceutical and food-grade facility clean rooms — application to concrete walls and floors in pharmaceutical clean rooms, food processing areas, and laboratory environments requiring a smooth, seamless, non-dusting, chemically resistant surface that meets hygiene and cleaning requirements; MC-Dur 2000 provides a hard, non-porous, seamless surface finish that eliminates the concrete surface microporosity where microbial contamination can harbour, can be cleaned with disinfectant solutions without degradation, and does not generate concrete dust or debris from surface abrasion — all critical requirements for pharmaceutical GMP and food safety hygiene standards

Key Advantages

• Two-component solvent-free formulation for zero or near-zero VOC emission during application — the solvent-free chemistry of MC-Dur 2000 eliminates the volatile organic compound (VOC) emissions of solvent-based epoxy coatings, making it compliant with Indian industrial workplace air quality requirements and with green building rating systems (IGBC, LEED) that specify low-VOC interior coatings; the solvent-free formulation also allows application in confined, enclosed, or poorly ventilated spaces (underground structures, enclosed tanks, basement WTP chambers) without the explosion or asphyxiation hazard of high-VOC solvent-based coatings — a significant practical safety advantage in Indian industrial maintenance and construction
• EN 1504-2 compliant concrete surface protection for structured asset management — MC-Dur 2000 compliance with EN 1504-2 (Products and Systems for the Protection and Repair of Concrete Structures, Part 2: Surface Protection Systems for Concrete) means it can be specified as part of a formal concrete asset protection strategy with documented performance classification (principle PI: Impregnation or principle C: Coating) and measurable acceptance criteria for bond strength (minimum 1.5 MPa pull-off per EN 1542), water vapour transmission (EN ISO 7783), CO2 permeability (EN 1062-6), and capillary absorption (EN 1062-3); this enables asset owners, project engineers, and consultants in Delhi NCR and Uttar Pradesh to write performance-based specifications for MC-Dur 2000 with measurable quality assurance criteria rather than purely prescriptive product specifications
