About Fosroc Nitoflor FC150-IM

Fosroc Nitoflor FC150-IM is a high-performance, solvent-free epoxy resin floor coating engineered for industrial environments where the floor takes a beating from chemicals, oils, grease and constant traffic. It belongs to Fosroc’s well-established Nitoflor range of resin floor coatings and toppings, and shares the chemistry of the standard Nitoflor FC150 system: epoxy resins and curing agents specifically selected for their ability to withstand chemical attack. The product is supplied as a pre-weighed kit comprising a base component, a hardener and a separate Nitoflor colour pack, all of which carry reactive elements essential to the cured system, so the kit must be used as supplied without adding thinners. Once mixed and applied, it cures to a seamless, jointless, impervious membrane that is far easier to clean and decontaminate than bare or screeded concrete. For contractors, consultants and facility owners across India, the appeal is straightforward: a coating that protects the concrete substrate, improves hygiene, brightens the working environment with a wide colour range, and keeps long-term maintenance costs down. The IM designation is the variant supplied for the Indian and certain regional markets; its product chemistry, build and performance mirror the parent FC150 system, and the Fosroc IM datasheet declares conformity to EN 13813 (the European standard for screed and floor coating materials), a minimum total dry film thickness of 0.5 mm and a substrate adhesion of not less than 1.6 MPa. Because it is solvent-free, there is no solvent odour during application, which matters in occupied or enclosed plants such as food and beverage facilities. Space Arc Engineering supplies and applies Nitoflor FC150-IM as an authorised Fosroc distributor and applicator serving Delhi NCR and pan-India projects.

The technical insight

The performance of any resin floor stands or falls on substrate preparation and the adhesive bond, not on the coating alone. Nitoflor FC150-IM is a coating-grade system (nominal 400-500 micron total build) rather than a self-levelling screed, so it follows the contours of the concrete and demands a sound, clean, mechanically prepared surface. New concrete should be at least 28 days old with moisture content below 5%; laitance must be removed by mechanical means (grinding or shot-blasting), not acid etching, which Fosroc explicitly does not recommend. The system is applied as two top coats, each a minimum 200 microns wet, with the second coat going down once the first reaches initial cure (12 hours at 20 degC, around 5 hours at 35 degC) and within the maximum recoat window of 36 hours at 20 degC (15 hours at 35 degC). Priming with Nitoprime 25 is only needed on porous or doubtful concrete. The cured film develops a 70 N/mm2 compressive strength, 40 N/mm2 flexural strength, 20 N/mm2 tensile strength, Shore D hardness of 85 and very low water absorption of 0.06% (ASTM C413), with broad chemical resistance verified to ASTM D543 over 7 days. A critical India-specific point is temperature: pot life roughly halves from 40 minutes at 20 degC to 20 minutes at 30 degC, and cure accelerates correspondingly, so on hot Indian sites the gang must mix smaller batches and move faster.

Where it is used

• Dairies, food-processing and meat/poultry units needing hygienic, washable floors
• Soft-drink production, bottling plants and breweries with wet, spill-prone areas
• Chemical manufacturing and process plants exposed to acids, alkalis and solvents
• Pharmaceutical and FMCG production and packaging halls
• Warehouses, godowns and logistics floors under wheeled and foot traffic
• Engineering workshops, assembly areas and maintenance bays exposed to oils and grease
• Commercial kitchens and beverage preparation areas
• Showrooms, internal car parks and basements needing a clean, coloured, dust-free finish

Key advantages

• Solvent-free formulation – no solvent odour during application, suited to occupied and enclosed plants
• Proven resistance to a wide range of industrial acids, alkalis, oils, fuels and solvents (tested to ASTM D543)
• Seamless, impervious, hygienic finish that is easy to clean and decontaminate
• Hard-wearing and abrasion resistant for durable, low-maintenance service
• Slip-resistant textures available via Nitoflor Antislip Grains to suit wet or trafficked areas
• Wide colour range to brighten work areas and demarcate hazard or zoning lines
• Liquid-applied, monolithic protection of the concrete substrate
• Pre-weighed packs reduce site mixing errors
• Conforms to EN 13813 with declared adhesion not less than 1.6 MPa

Limitations & considerations

• Not for substrates suffering rising damp, potential osmosis or relative humidity above 75% (per BS 8203 Appendix A)
• Coating-grade build (approx. 0.4-0.5 mm), not a self-levelling screed – it follows existing floor profile and won’t level undulations or take heavy impact like a thick screed
• Pot life is short and drops sharply in heat (about 40 min at 20 degC, 20 min at 30 degC), demanding disciplined batch sizing on hot Indian sites
• Requires properly cured (28-day), dry (under 5% moisture) and mechanically prepared concrete; acid etching is not recommended
• New concrete must be sound and free of laitance, curing-compound residue, oil and grease before coating
• Epoxy chemistry can show slight shade change and reduced gloss under prolonged UV or extreme heat-and-humidity exposure (cosmetic, not structural)
• Contains reactive epoxy components – skin/eye protection and ventilation needed during mixing and laying

How we position Fosroc Nitoflor FC150-IM

Nitoflor FC150-IM sits in Fosroc’s coating-grade tier of the Nitoflor range – a robust, chemical-resistant epoxy coating for sound concrete, rather than a heavy-duty self-levelling or screed product. Within the Fosroc family it pairs naturally with Nitoprime 25 (primer), Nitomortar and Nitoflor EU5 (substrate repair), and Nitoflor Antislip Grains (texture); where a thicker, self-smoothing finish is needed, specifiers typically step up to Nitoflor self-levelling toppings, and for heavy-impact or thermal-shock service to a Nitoflor or Conflor screed-grade system. Against the wider Indian market, credible alternatives in the same solvent-free epoxy floor-coating class include Sika (Sikafloor range, e.g. Sikafloor-264/-161 build-ups), MBCC/Master Builders Solutions (MasterTop epoxy coatings), STP Limited (Vetonit/epoxy flooring lines) and, in the value/retail segment, Pidilite Dr. Fixit Roffe epoxy coatings; BASF-legacy and Ardex systems also compete on larger specifications. FC150-IM differentiates on Fosroc’s long India track record, pre-weighed packs, broad chemical-resistance data and the support of authorised applicators. For most Indian food, beverage, chemical and warehousing floors it is a dependable specification; the right choice between it and the alternatives usually comes down to required build thickness, chemical exposure, downtime tolerance and applicator availability. Space Arc Engineering, as an authorised Fosroc distributor and applicator across Delhi NCR and pan-India, can advise on the correct Nitoflor build-up and supply the matching primer, repair and antislip products for a complete system.
