MC-Bauchemie MC-DUR 140 IN
A high-build, two-pack epoxy coating engineered for oil, chemical and abrasion resistance — from car parks to pharma floors.
What is it?
A two-component, solvent-based epoxy coating — pigmented base (Part A) plus hardener (Part B) — applied over concrete, steel or masonry in two coats.
Where is it used?
Car parks, ramps, fuel stations, workshops, warehouses, and chemical, pharma, food-processing and dairy floors across Delhi NCR and pan-India sites.
Why use it?
Turns bare concrete or steel into a seamless, dust-free, easy-clean surface resisting diesel, dilute acids/alkalis, solvents, abrasion and light-medium traffic.
How is it applied?
Part A and B are mixed 5:1 by weight with a slow paddle mixer, then rolled or brushed on in two 200-micron coats, the second at right angles to the first.
About MC-Bauchemie MC-DUR 140 IN
Most industrial floor failures in India start not with the concrete but with what gets spilled, driven or wheeled across it — diesel in a basement car park, acid splashes on a pharma floor, years of forklift traffic in a warehouse. MC-DUR 140 IN is MC-Bauchemie’s answer: a straightforward two-component epoxy built to be genuinely multipurpose rather than optimised for one setting. It cures into a hard, chemically inert film that bonds to concrete, steel and masonry alike, which is why it turns up on such a wide spread of floors.
What makes it a practical everyday spec is the packaging of choices: a 400-micron smooth system for general industrial and pharma/food floors, and a thicker 0.75-2 mm anti-slip broadcast system for car parks and ramps, both off the same base product. For Indian conditions, the 40-minute pot life at 25°C is the number site supervisors must plan around — it shrinks further in summer heat, so batch sizes need to track ambient temperature. Space Arc supplies and applies MC-DUR 140 IN within its authorised MC-Bauchemie flooring range, sequencing prep, priming and coating to the data sheet’s stated rates.
The technical insight
Chemically this is a conventional epoxy-amine system: the resin in Part A cross-links with the amine hardener in Part B into a rigid duromer network, mixed at 5:1 with a 40-minute pot life at 25°C. That structure delivers the 55 N/mm² compressive strength and Shore D 75 hardness at 7 days, explaining resistance to abrasion and point loading, not just chemicals. Coverage is quoted per coat (200 g/m²), so a 400-micron two-coat system needs both coats costed, plus a primer allowance on porous concrete. The +10°C to 35°C application window isn’t arbitrary — cure slows in the cold and pot life collapses in the heat, so both extremes affect film quality.
Where it is used
- Multi-level and basement car parks, ramps and driveways with oil/fuel exposure
- Petrol pumps, fuel depots and vehicle wash bays needing diesel-resistant flooring
- Chemical process areas and bunded tank floors exposed to dilute acid/alkali
- Pharma manufacturing and packing floors needing a seamless, dust-free finish
- Food and beverage plants, bottling lines and dairies with frequent washdown
- Workshops and warehouses with trafficked structural concrete floors
- Steel tanks and structural steel in corrosive or chemically active zones
- Institutional/commercial basements needing a hard-wearing, low-maintenance floor
Key advantages
- Genuinely multipurpose — one base covers smooth and anti-slip broadcast systems
- Broad chemical resistance to diesel, dilute acids/alkalis and solvents
- Good abrasion and mechanical resistance for light-to-medium traffic
- Seamless, easy-to-clean film — a real plus for hygiene-sensitive floors
- Adheres well to concrete, steel and masonry alike
- Reasonably fast turnaround — tack-free in 7 hours, hard in 24 hours
- Practical 6 kg and 20 kg packs suited to small jobs and full rollouts
- Clearly documented two-coat, cross-hatch method reduces site guesswork
Limitations & considerations
- Needs sound concrete of 25 N/mm² strength and 1.5 N/mm² pull-off; poor prep shows as adhesion failure
- Not UV-stable alone — sunlit areas need an MC-DUR 215 UVR topcoat
- Temperature-bound — application stops below +10°C and above 35°C surface temperature
- Only a 40-minute pot life at 25°C, tighter in Indian summer heat
- Not self-levelling — follows the substrate profile rather than correcting it
- Solvent-cleanable only; water or water-based cleaners must never be used
Selection & best practice
Treat surface prep as the real determinant of performance. Confirm the substrate meets 25 N/mm² compressive strength and 1.5 N/mm² pull-off, and prime porous slabs at 125-150 g/m² — skipping this is the commonest cause of pinholing. Mix the base for two minutes, add hardener, mix a further three minutes at low speed, and size batches to the 40-minute pot life, smaller in hot weather. Apply the first coat in one direction and the second, once dry, at right angles, holding 200 microns WFT per coat. Keep temperature between +10°C and 35°C, clean tools only with MC-Thinner EP, and topcoat with MC-DUR 215 UVR wherever the floor sees sunlight.

How we position MC-Bauchemie MC-DUR 140 IN
Within MC-Bauchemie’s own range, MC-DUR 140 IN is the general-purpose epoxy workhorse: the data sheet points to MC-DUR EP as the porous-substrate primer, Nafuquick range mortars for patching before coating, and MC-DUR 215 UVR as the topcoat for sunlit floors, so a full Space Arc spec often bundles two or three of these. The closest genuine market equivalent is Fosroc’s Nitoflor FC150 — also a two-coat, ~400-micron high-build epoxy for the same car-park, dairy and chemical-plant floors — where the choice usually comes down to applicator familiarity rather than a real performance gap. Sika’s Sikafloor range and self-levelling PU systems sit in adjacent niches, better suited to self-smoothing or immersion-grade duty.
Fosroc Nitoflor FC150 — A specifier already standardised on Fosroc, or needing a slightly harder/higher-strength high-build epoxy (Shore D 85, 70 N/mm² compressive vs MC-DUR 140 IN’s 75/55), might choose Nitoflor FC150 over MC-DUR 140 IN for an equivalent two-coat car-park or chemical-plant floor.
