About Master Builders Solutions Ucrete MF40AS

Ucrete MF40AS from Master Builders Solutions is the antistatic member of the Ucrete MF family — the same dense polyurethane concrete that has protected aggressive process floors for decades, reformulated to bleed static charge safely to earth. Laid at 4 to 6 mm, it gives a smooth, seamless, easy-clean surface in a usefully wide colour palette, including the lighter greys and creams that electronics and pharma clients increasingly specify for bright, auditable production spaces.

For Indian facilities, the case is practical. Component-level ESD damage rarely announces itself at the line; it shows up months later as field failures and warranty claims. A floor that holds resistance-to-ground below 1 × 10⁶ ohm and keeps body-voltage generation under 100 V removes the largest uncontrolled surface in the room from that risk equation. Because the binder is Ucrete rather than a conventional epoxy, the same floor also shrugs off acid and alkali spillage, solvent wipe-downs, pallet-truck impact and service temperatures from −15 °C to +70 °C. Space Arc Engineering supplies the full system and installs it through trained crews across Delhi NCR and pan-India.

The technical insight

Static control here is a system, not a coating. Copper earthing tape is bonded to the building’s earth points and laid as a grid across the slab, then locked in with a conductive primer that forms a continuous equipotential plane. The MF40AS wearing body above it carries conductive media distributed through the polyurethane concrete matrix, so charge generated at the surface — footfall, trolley wheels, powder movement — finds a low-resistance path down to the grid faster than it can accumulate. That is why the floor is verified two ways: resistance-to-ground (below 1 × 10⁶ ohm, testable to EN 1081) and body-voltage generation (below 100 V on a walking person), meeting BS 5958, DIN 51953 and EN 61340 requirements. Mechanically, the PU-concrete chemistry cures to around 50 N/mm² compressive strength but with a lower elastic modulus than epoxy, so point loads and dropped tooling deform the floor microscopically instead of cracking it.

Where it is used

• Electronics, PCB and component assembly halls operating as ESD-protected areas
• Pharmaceutical production suites, packing halls and cleanroom corridors
• Solvent stores, charging rooms and powder-handling bays in explosion-hazard classified zones
• Laboratories and QC areas handling flammable reagents
• Dry-process food manufacturing and packaging floors
• Warehouses and dispatch zones serving static-sensitive inventory
• Refurbishment of failed epoxy ESD floors where chemical attack or impact was the cause

Key advantages

• Certified static performance: resistance-to-ground below 1 × 10⁶ ohm and body-voltage generation under 100 V, meeting BS 5958, EN 1081, DIN 51953 and EN 61340
• Ucrete chemical resistance — withstands a broad register of acids, alkalis and solvents, including spillage and discharge up to +70 °C
• Serves from −15 °C freezer conditions to +70 °C without losing grip on the substrate
• High mechanical strength (about 50 N/mm² compressive) with a resilient, low-modulus matrix that absorbs impact and point loads
• Fast programmes: tolerant of 7-day-old and damp (properly prepared) concrete, with return to light traffic inside 24 hours at +18 °C
• Dense, impervious, seamless finish that cleans easily and does not harbour bacteria
• Bfl-s1 reaction-to-fire classification to EN 13501-1
• Available in light, bright colours — a genuine step forward for antistatic PU-concrete floors

Limitations & considerations

• ESD performance depends on the whole build-up — earthing grid, conductive primer and wearing layer installed correctly. It is not a paint-on antistatic coating and should only go down through trained applicators.
• Intended for predominantly dry process areas; for wet production with heavy thermal shock and steam cleaning, a thicker textured grade such as Ucrete UD200 is the better specification.
• The smooth R10 surface suits dry traffic. Where oils, fats or wet processes create slip risk, choose a profiled Ucrete grade instead.
• Upper service limit is +70 °C — hot-oil discharge or steam above this needs a heavier Ucrete system, not MF40AS.
• Requires a sound substrate of roughly 30 N/mm² compressive strength; weak screeds must be removed before installation.
• Certified EPAs need periodic resistance verification after handover — budget for routine ESD audits, not just the installation.

Industry use cases

How we position Master Builders Solutions Ucrete MF40AS

Within the Master Builders Solutions family, MF40AS sits between standard Ucrete MF — the same smooth 4–6 mm floor without static control, for general dry process areas — and the heavy-duty grades: Ucrete UD200 for wet production with thermal shock and steam cleaning, and profiled Ucrete DP grades where slip resistance governs. For light-duty dry rooms on tighter budgets, MasterTop epoxy self-levellers are the honest downgrade. Among our other brand lines, Sikafloor ESD epoxy systems suit server rooms and electronics stores with lighter mechanical duty, while Fosroc Nitoflor covers general industrial floors without ESD needs. Space Arc supplies and installs all of these, so specify by exposure, not by habit — call us to match the grade to the room.
