MC-Bauchemie MC-Dur 2000
A solvent-free, high-build epoxy barrier coating that shields concrete and structural steel from chemical attack and corrosion in demanding industrial service.
What is it?
A two-component, solvent-free epoxy protective coating and anti-corrosion primer from MC-Bauchemie, built up in thick films over concrete and steel.
Where is it used?
Aggressive industrial environments — process plants, effluent and chemical areas, tank farms, structural steelwork and RCC exposed to spills, fumes and washdown.
Why use it?
It forms a dense, low-permeability barrier that resists dilute acids, alkalis, oils and solvents while slowing corrosion of the substrate beneath.
How is it applied?
Blast- or mechanically-prepared surface, mixed A+B, then roller- or brush-applied in two to three coats to reach the specified dry film thickness.
About MC-Bauchemie MC-Dur 2000
MC-Dur 2000 is a two-component, solvent-free epoxy coating engineered by MC-Bauchemie to protect concrete and structural steel that sits in the firing line of industrial chemistry. It combines a bisphenol-A epoxy resin (Component A) with an amine hardener (Component B); once the two are blended, they cure into a hard, tightly cross-linked film that behaves as a continuous barrier rather than a decorative paint. Because it carries no solvent, the coating builds to high film thickness in a single pass without the shrinkage, pinholing or lingering odour that plague solvented systems — which is exactly why specifiers reach for it inside tanks, sumps and other confined spaces where ventilation is poor.
For contractors and consultants across Delhi NCR and the rest of India, the appeal is practical. A plant owner rarely cares about resin chemistry in the abstract; they care that a bund wall, a pump plinth or a steel gantry survives years of acid mist, oil drips and pressure washing without spalling or rusting through. MC-Dur 2000 answers that by giving both a chemical-resistant surface and an anti-corrosion primer function in one product family. Space Arc Engineering supplies the material and, where required, applies it under supervision — handling the surface preparation, mixing discipline and film-thickness checks that decide whether an epoxy system lasts a decade or fails in a monsoon.
The technical insight
The protection comes down to barrier performance and film density. When Components A and B react in the correct ratio, the amine hardener opens the epoxy rings and knits the resin into a three-dimensional network with very few unreacted sites for aggressive media to attack. That dense matrix has a low water-vapour transmission rate, so moisture, chloride ions and dissolved acids struggle to diffuse through to the concrete or steel underneath. On steel, that same impermeability starves the corrosion cell of the water and oxygen it needs, which is why the system doubles as an anti-corrosion primer rather than merely a topcoat. Getting there depends on chemistry meeting craft: the resin must cure between +8 and +35 degrees Celsius on a dry substrate, and the applied film has to reach the specified thickness in every coat. Too thin, and the barrier has weak points; too much in one pass on an unforgiving surface, and it can sag. High-build capability is the point — it lets the applicator reach 300 to 500 microns of dry film per coat where a conventional paint would need many more passes to match it.
Where it is used
- Chemical, fertiliser and process plants where structures face acid, alkali or solvent exposure
- Effluent and sewage treatment tanks, channels and sumps
- Bund walls, secondary containment and spillage-prone flooring plinths
- Structural steel gantries, columns and pipe supports in corrosive atmospheres
- RCC members in tank farms, pump houses and loading bays subject to washdown
- Petroleum, oil and lubricant storage and handling areas
- Confined or poorly ventilated interiors where solvented coatings are impractical
- Marine and coastal industrial assets exposed to chloride-laden air
Key advantages
- Solvent-free formulation with near-zero VOC, safe for confined and enclosed spaces
- High-build capability delivers 300-500 microns dry film per coat, cutting the number of passes
- Broad chemical resistance to dilute acids (pH 3-11), alkalis, petroleum oils and aliphatic solvents
- Dense, low-permeability film that resists moisture and chloride ingress
- Acts as both a protective coating and an anti-corrosion primer, simplifying the build-up
- Bonds well to properly prepared concrete and structural steel
- Meets recognised standards for concrete surface protection and atmospheric corrosion
- Backed by Space Arc’s local supply and supervised application across Delhi NCR and Pan-India
Limitations & considerations
- Not designed for continuous immersion in concentrated acids or strong oxidising chemicals — confirm the exposure against the media list
- Substrate must be dry and free of standing water; damp or green concrete will compromise adhesion
- Application is temperature-sensitive and needs the substrate held between +8 and +35 degrees Celsius
- Short pot life of roughly 30-45 minutes at 25 degrees means only workable quantities should be mixed at a time
- Epoxy films can chalk and lose gloss under prolonged direct UV — a pigmented UV-stable topcoat is advisable for exposed steelwork
- Full chemical-resistance cure takes about 7 days, so the area must stay out of service until then
Selection & best practice
Success with MC-Dur 2000 is decided before the first coat goes on. Concrete should be sound, clean and dry, with laitance removed by grit blasting, shot blasting or diamond grinding to open the surface; steel needs blast cleaning to a bright profile so the primer can key in. Mix Component A and Component B strictly by the ratio and time stated on the batch data sheet, using a slow-speed stirrer, and blend only what the crew can lay within the pot life. Apply by roller or brush in two to three coats, checking wet-film thickness as you go to land in the 300-500 micron per-coat band and reach the total dry film the specification calls for. Respect the overcoat window between coats, keep the substrate temperature inside the +8 to +35 degrees Celsius range, and protect fresh film from rain, dust and traffic. Allow the full cure period before returning the structure to chemical service. Where the coating faces sunlight or a decorative finish is wanted, plan a compatible topcoat into the system from the start.

Coats RCC and steel in process areas exposed to acid mist, alkali splashes and solvent spills, holding the barrier intact through repeated washdown.
Water & Effluent Treatment
Lines tanks, channels and sumps where dilute acids, alkalis and biological effluent would otherwise degrade concrete over time.
Oil, Petroleum & Storage
Protects tank-farm structures, bund walls and containment floors against hydrocarbon contact and corrosion in loading and handling zones.
Heavy Industry & Infrastructure
Shields structural steel gantries, columns and pipe racks in corrosive plant atmospheres, doubling as an anti-corrosion primer beneath a topcoat.

How we position MC-Bauchemie MC-Dur 2000
MC-Dur 2000 sits in the protective-coatings and corrosion-control line, alongside MC-Bauchemie’s own MC-Color 2K and MC-Color E finishing coats, which can serve as pigmented or UV-stable topcoats over the epoxy barrier. For flooring in the same plants, the Master Builders Solutions MasterTop 1202 and MasterTop 1705 epoxy floor systems complement the wall and steel protection MC-Dur 2000 provides. Where the driver is condensation control or facade weatherproofing rather than chemical attack, Dr. Fixit Mouldshield and Raincoat from our wider range are the better fit. Talk to Space Arc so the coating is matched to the actual exposure rather than specified by habit.
Fosroc Nitocote EN901 — A specifier facing the harshest chemical service — concentrated acids or the full pH 1-14 range in effluent, desalination or refinery structures — may prefer this solvent-free epoxy novolac, which offers broader chemical resistance than a standard bisphenol-A epoxy coating.
