MC-Bauchemie MC-DUR 1105 SL-IN
A 500-micron, three-component epoxy self-levelling coating built to shrug off diesel, dilute acids and daily abrasion on real Indian industrial and automotive floors.
What is it?
A three-component, pigmented epoxy resin self-levelling (SL) floor coating engineered as a thin, seamless topping applied at roughly 500 microns (0.5mm) per coat.
Where is it used?
Car parks, service bays, garages, petrol pumps and car-wash aprons; chemical, pharmaceutical, food-processing, bottling and dairy plant floors — anywhere over a sound mineral or steel substrate.
Why use it?
Good chemical and abrasion resistance, resistance to diesel oil/dilute acids/alkalis/many solvents, a seamless easy-to-clean surface, and strong adhesion to concrete and steel.
How is it applied?
Substrate is prepared, tested and primed with an MC-DUR range primer (scratch coat if porous); the mixed three-part material is poured and spread with a steel float, pin float or rubber squeegee, then de-aerated with a spiked roller, with an optional quartz-sand broadcast for anti-slip texture.
About MC-Bauchemie MC-DUR 1105 SL-IN
MC-Bauchemie (India) Private Limited, B-501, Shelton Sapphire, Sector-15, CBD Belapur, Navi Mumbai 400614, India, Tel: 022- 27563867/ 27570803 / 27572856, e-mail: [email protected] www.mc-bauchemie.com. MC-DUR 1105 SL-IN (formerly sold in India as MC DUR ESL 500) is a three-component, pigmented epoxy resin coating from MC-Bauchemie’s MC-DUR flooring range, built as a thin self-levelling (self-smoothing) topping applied at roughly 500 microns (0.5mm) per coat. The three parts — a resin base, a colour paste and a hardener, bulked out with a filler component — are mixed in a fixed ratio and poured onto a primed concrete or steel substrate, then spread with a steel float or squeegee and de-aerated with a spiked roller to leave a seamless, glass-smooth film once cured.
It isn’t marketed as a heavy structural screed. At half a millimetre per coat, it’s engineered to turn a porous, dust-shedding concrete floor into a sealed, chemical- and abrasion-resistant surface that’s easy to hose down and keep clean — which is exactly what car workshops, petrol pumps, and food and pharma plants ask for. For Space Arc’s Delhi NCR and pan-India project sites, that combination of oil/diesel resistance, dilute-acid and alkali resistance, and a seamless finish makes it a sensible specification wherever hygiene and chemical spillage — rather than sheer floor-load — are the driving concerns.
The technical insight
The “three-component” description matters more than it sounds. The fixed mixing ratio on the TDS — roughly 2.0 parts resin : 0.3 parts colour paste : 1.2 parts hardener : 3.55 parts filler, by weight — means the filler is doing real structural work, building body into what would otherwise be a thin, brittle film and helping the coating hit its stated 500-micron DFT and >50 N/mm² compressive strength (at 7 days) in one controlled pour rather than several thin coats. The Shore D hardness curve — 60 at 1 day, rising to 74 at 7 days — is a useful practical signal: the floor is walkable and takes light use well before it has developed its full chemical and abrasion resistance, so the 7-day full-cure window at 20°C is a genuine engineering requirement, not manufacturer caution. Worth noting for anyone who has seen the older name on a quotation or packaging: MC-DUR 1105 SL-IN was previously sold in India as MC DUR ESL 500 — same formulation, current designation.
Where it is used
- Self-levelling epoxy flooring for oil- and diesel-exposed automotive floors — car parks, service bays and garages
- Petrol pump forecourts and car-wash aprons needing fuel and chemical resistance
- Chemical process areas requiring resistance to dilute acids, alkalis and organic solvents
- Pharmaceutical plant floors needing a dust-free, easy-to-sanitise seamless surface
- Food processing, bottling and dairy plant floors requiring hygienic washdown surfaces
- Light industrial and warehouse floors over sound mineral substrates
- Renovation topping over old, stripped or repaired concrete and screed floors
- Steel substrate coating where good adhesion and chemical resistance are both needed
Key advantages
- Seamless, dust-free finish that is easy to clean and hold to hygiene standards
- Good resistance to diesel oil, dilute acids, alkalis and numerous organic solvents
- Strong adhesion to both concrete and steel substrates
- High abrasion resistance suited to daily foot and light wheeled traffic
- Thin ~500-micron build per coat keeps floor-to-door and floor-to-drain clearances intact
- Optional quartz-sand broadcast lets applicators dial in anti-slip texture where wash-bay or ramp areas need it
- Pigmented system available in a range of shades for zone marking or aesthetics
- Backed by MC-Bauchemie’s India-based technical and application support network
Limitations & considerations
- A thin (0.5mm) coating system, not a load-bearing screed — not the right spec for sustained forklift or heavy trolley traffic
- Short 30-40 minute pot life at 30°C demands disciplined small-batch mixing and trained applicators, especially in Indian summer heat
- Needs a genuinely sound, cured substrate (minimum 28 days, >25 N/mm² compressive strength, ≥1.5 N/mm² pull-off, <5% moisture) — shortcuts on prep show up as delamination
- Requires a separate MC-DUR primer, and often a scratch coat on porous substrates — factor that into total system cost and programme, not just the coating price
- Like most epoxies, not intended for long-term outdoor UV exposure — best specified for indoor or covered areas
- The manufacturer TDS on file doesn’t quote a specific IS/ASTM/EN standard number — buyers needing certified third-party conformance should request supplementary documentation from MC-Bauchemie
Selection & best practice
Treat surface preparation as the real determinant of performance: the substrate should be fully cured (minimum 28 days old), mechanically prepared to remove laitance, oil, grease and any old coatings, and checked for moisture content (max. 5%), minimum compressive strength (>25 N/mm²) and pull-off strength (≥1.5 N/mm²) before anything is primed. Prime with an MC-DUR range primer, adding a quartz-sand scratch coat (0.1-0.3mm sand mixed 1:1 with primer by weight) on porous or pitted concrete so the SL coat doesn’t telegraph pinholes or blowholes. Mix strictly to sequence — base and colour paste together first, then the hardener (minimum 2 minutes), then the filler last (a further 3 minutes) — using a slow paddle mixer (max. 300 rpm) to avoid whipping air into the mix, and keep batch sizes matched to the 30-40 minute pot life rather than mixing large batches to save time. Pour, spread and de-air promptly with a spiked roller, and hold air/material/substrate temperature within 10-30°C with relative humidity ≤85% and substrate temperature at least 3K above dew point — Indian monsoon humidity and summer heat can both push a site outside that window if it isn’t actively monitored.

How we position MC-Bauchemie MC-DUR 1105 SL-IN
Within MC-Bauchemie’s own MC-DUR flooring family, 1105 SL-IN sits at the thin, self-levelling end of the range — specify it with an MC-DUR range primer (and MC-Clean EP for tool cleaning) rather than as a stand-alone product, and step up to MC-Bauchemie’s thicker trowel-applied MC-DUR screed and topping systems where the floor must carry sustained forklift or heavy-trolley traffic. In the Indian market, the nearest genuinely comparable systems are Fosroc’s Nitoflor SL range and Sika’s Sikafloor SL range, both competing in the same self-smoothing epoxy-flooring segment. Specifiers wanting a slightly thicker, four-component build with a bit more film integrity for light-industrial floors sometimes prefer Fosroc Nitoflor SL2000 over the thinner 1105, while 1105 SL-IN stays the more economical choice where minimal build-up or budget rules out a thicker topping.
Fosroc Nitoflor SL2000 — Specifiers sometimes prefer Nitoflor SL2000 when the floor needs a slightly thicker (2mm), four-component self-smoothing build for light-industrial or cleanroom-adjacent areas, rather than 1105 SL-IN’s thinner 0.5mm overcoat.
