About MC-Bauchemie MC-DUR 300

MC-DUR 300 belongs to MC-Bauchemie’s MC-DUR programme, the German manufacturer’s established line of two-component epoxy resin coatings for industrial floors and concrete protection. Like the rest of that family, it is a solvent-free, pigmented epoxy that is mixed on site from a resin base and a hardener, then rolled or squeegeed onto a properly prepared mineral substrate. Once cured it forms a continuous, tightly bonded film that closes the surface porosity of concrete and gives it a hard, wearable, wipe-clean finish. The intent is straightforward: take an ordinary power-floated or screeded slab that would otherwise dust, stain and wear under service, and turn it into a sealed working surface that stands up to traffic, occasional chemical contact and regular washdown.

For engineers and facility owners in India, the appeal is practical rather than cosmetic. Bare concrete in a busy plant abrades under forklift and pallet movement, absorbs oils and process chemicals, and sheds fine dust that fouls products and equipment. An epoxy coating in the MC-DUR class addresses all three at once. Space Arc Engineering supplies MC-DUR 300 as an authorised MC-Bauchemie distributor and applicator, and because the exact figures that matter on site — pack size, coverage per coat, pot life and full-cure time — are governed by the current MC-Bauchemie technical data sheet for the grade, we confirm those against the live datasheet for your batch rather than quoting numbers that may have shifted between revisions.

The technical insight

The performance comes from epoxy crosslinking chemistry. The two components are supplied in a fixed ratio; when the amine-type hardener is stirred into the epoxy resin base, the two react and cure into a dense, three-dimensional thermoset network rather than simply drying. That cured matrix is what gives the film its hallmarks: strong adhesion into the concrete pore structure, low permeability, and resistance to abrasion and to a range of acids, alkalis and solvents. Because the system is solvent-free and close to 100% solids, almost the entire wet film stays on the floor as cured coating, so there is minimal shrinkage and no solvent flash-off thinning the build. The catch is that this is a reactive, time-limited process. Once mixed, the material has a finite pot life during which it must be applied, and it must go onto a substrate that is sound, clean and within the moisture limit set by the datasheet — epoxy will not bond reliably to a slab that is damp, laitance-covered or contaminated. Get the preparation and the mixing right and the coating behaves as a monolithic protective skin; get them wrong and it delaminates regardless of the resin quality.

Where it is used

• Sealing and protecting concrete floors in warehouses and distribution centres against forklift and pallet-truck abrasion
• Coating production and manufacturing hall floors that face mechanical load and occasional chemical spillage
• Providing a closed, dust-free, wipe-clean surface in workshops, assembly bays and maintenance areas
• Protecting storage-area and racking-aisle floors that need to resist wear and stay easy to clean
• Lining process and plant-room floors exposed to intermittent contact with oils, mild acids or alkalis
• Refurbishing tired, dusting concrete slabs to restore a hard, hygienic working surface
• Creating a hardwearing decorative finish where a uniform, coloured floor is specified
• Protecting concrete substrates in industrial units across Delhi NCR and Pan-India project sites

Key advantages

• Two-component, solvent-free (100% solids) epoxy — low odour and minimal shrinkage on cure
• Forms a seamless, closed film that stops concrete dusting and makes floors easy to clean
• Genuine resistance to abrasion and to a range of acids, alkalis and solvents once fully cured
• Bonds strongly into prepared concrete for a durable, hardwearing protective skin
• Backed by MC-Bauchemie’s German formulation and quality control as part of the established MC-DUR range
• Available pigmented for a uniform coloured finish, improving light reflectance and housekeeping
• Applied by roller or squeegee, so large floor areas can be coated efficiently
• Supplied and applied by Space Arc as an authorised MC-Bauchemie distributor with technical support across India

Limitations & considerations

• Not a repair mortar — it is a coating, so cracks, spalls and level defects must be repaired with the correct patching or screed product before coating
• Reactive two-part system with a limited pot life; mixed material must be used promptly and cannot be reclaimed once it starts to gel
• Adhesion depends entirely on substrate preparation — damp, laitance-covered, oily or weak concrete will cause delamination
• Sensitive to substrate moisture and application temperature; the datasheet limits must be respected or cure and bond suffer
• Standard epoxy films can chalk and lose gloss under sustained UV, so exterior or sunlit exposure needs the right grade or a topcoat
• The area must be taken out of service during application and cure, which needs planning around plant operations

Industry use cases

How we position MC-Bauchemie MC-DUR 300

MC-DUR 300 sits in the protective-coatings side of the MC-Bauchemie portfolio, alongside the wider MC-DUR epoxy floor-coating range — food-grade and potable-water grades such as MC-DUR EPW, and heavier industrial systems in the MC-DUR family for aggressive chemical or high-wear duty. Where the substrate itself needs rebuilding before coating, pair it with an MC-Bauchemie concrete repair mortar (Emcefix / MC-RIM lines) rather than expecting a coating to fill structural defects. Against our other brands, specifiers who want an equivalent two-component solvent-free epoxy from a different house can consider Fosroc’s Nitocote epoxy coatings or Sika’s Sikafloor epoxy systems; the right choice usually comes down to the specified chemical exposure, colour and the approvals your project or consultant already recognises. Our team can cross-map any of these to the exact duty of your floor.
