Fosroc Nitocote EP175
A three-component, high-solids epoxy resin coating that delivers a hard-wearing, chemically resistant, semi-gloss finish for industrial floors, walls and food-grade production areas.
What is it?
A three-component, high-solids, solvent-based epoxy resin coating supplied in pre-weighed packs (base, hardener and colour pack) that cures to a hard, durable, semi-gloss, impervious film.
Where is it used?
Production and assembly areas, workshops, dairies, soft-drink production and bottling plants, kitchens, showrooms, and other industrial spaces needing a tough, easy-to-clean, chemical-resistant surface.
Why use it?
It combines high abrasion resistance, resistance to a wide range of industrial chemicals, and a hygienic, washable finish at a higher film build than thin-film coatings, with low long-term maintenance cost.
How is it applied?
Apply by brush or lambswool roller in two coats over a clean, dry, primed substrate (Nitoprime 25), allowing the stated overcoat interval between coats.
About Fosroc Nitocote EP175
Fosroc Nitocote EP175 is a high-performance protective coating built around a three-component, high-solids epoxy resin system. Unlike many single- or two-pack coatings, it ships in pre-weighed packs that already include the pigment (colour pack) alongside the base resin and hardener, so the contractor mixes a balanced, controlled system on site rather than batching components by eye. Once cured, the coating forms a hard, durable, semi-gloss film that bonds well to clean concrete, sand/cement and granolithic screeds, Fosroc epoxy screeds, and certain prepared metal surfaces.\n\nThe product sits in the family of Fosroc Nitocote epoxy coatings, where the EP175 designation reflects its intended wet film build of around 175 microns per coat. That higher build, compared with thinner sealers, is the whole point: EP175 is positioned for areas where a thicker, more robust coating is required to absorb mechanical wear and resist repeated chemical contact and wash-downs. With a solids content of 75% by volume and two-coat application, it lays down a substantial, impervious barrier rather than a cosmetic skin.\n\nFor Indian contractors, consultants and facility owners, EP175 is relevant wherever a floor or surface must stay hygienic, hard-wearing and easy to clean under genuine industrial duty – dairy halls, beverage bottling lines, commercial kitchens, engineering workshops and customer-facing showroom floors. It is a coating chosen for performance and cleanability, supplied through Fosroc’s authorised distribution network including Space Arc Engineering across Delhi NCR and Pan-India.
The technical insight
The defining characteristic of Nitocote EP175 is its high-build, high-solids chemistry. At 75% solids by volume and a recommended 175 microns wet film thickness per coat, a single coat consolidates to roughly 130 microns dry film thickness (DFT), so a two-coat system builds a substantial, continuous epoxy barrier – far heavier than thin sealer-type coatings. Coverage is approximately 5.5 m2 per litre per coat at 175 microns WFT before allowing for wastage and substrate porosity. Because it is solvent based, the product has a flash point of 23 degrees Celsius and must be handled away from ignition sources with adequate ventilation. Cure behaviour is strongly temperature dependent: pot life runs about 3 hours at 20 degrees Celsius but falls to roughly 1.5 hours at 35 degrees Celsius – a critical planning factor in Indian summer site conditions, where mixed material must be applied quickly before viscosity climbs. Time between coats is 12-24 hours at 20 degrees Celsius and 6-12 hours at 35 degrees Celsius, with full chemical cure at about 10 days (20 degrees) or 7 days (35 degrees). The coating resists 10% citric, hydrochloric, lactic and sulphuric acids, which underpins its use in food, dairy and beverage environments where dilute acids are routinely present.
Where it is used
- Hard-wearing floor coating for engineering workshops and production/assembly areas
- Hygienic, washable coating for dairies, soft-drink production and bottling plants
- Chemical-resistant surfacing for commercial and institutional kitchens
- Decorative yet durable showroom and retail-area floors
- Protective topcoat over Fosroc epoxy resin screeds
- Coating for sound, primed concrete, sand/cement and granolithic screeds
- Coating for prepared and primed metal surfaces requiring a tough epoxy film
Key advantages
- High solids (75% by volume) high-build film for a substantial protective barrier
- Very hard wearing and durable, reducing long-term maintenance cost
- High resistance to a wide range of industrial chemicals, including dilute acids
- Hygienic, impervious, semi-gloss finish that is easy to clean and wash down
- Pre-weighed three-component packs (including colour) minimise on-site mixing error
- Good adhesion to concrete, screeds, epoxy screeds and certain prepared metals
- Available in a range of colours to improve the working environment
- Straightforward application by brush or lambswool roller
Limitations & considerations
- Solvent based with a 23 degrees Celsius flash point – requires good ventilation and ignition control
- Short pot life in heat (about 1.5 hours at 35 degrees Celsius), demanding fast, planned application
- Must not be applied where substrate humidity exceeds 75% (tested per BS 8203 Appendix A)
- Being a relatively thin coating, surface imperfections in the substrate can show through and wear at high spots
- As an epoxy, it can chalk, gloss-reduce and yellow under sustained UV/sunlight, so it is best suited to interior use
- Fosroc does not recommend acid etching as a substrate preparation method
- Hardened over-spill or cured material can only be removed mechanically
- Metal substrates need grit blasting to SA 2.5 and priming with Nitoprime 25 for reliable adhesion
Selection & best practice
Apply Nitocote EP175 only to sound, clean, dry substrates with relative humidity below 75% verified per BS 8203 Appendix A or with a Protimeter thermohygrometer. Prime the prepared surface with a single coat of Nitoprime 25; for steel, grit blast to SA 2.5 (BS 4232 Second Quality) before priming. Stir base and hardener separately, then combine the entire pre-weighed pack contents – including the colour part – and power-mix with a paddle for at least three minutes, scraping all containers clean to keep the ratio correct. In warm conditions, mix only what the team can lay within the pot life and plan around the much shorter working time at 35 degrees Celsius. Apply two coats by brush or lambswool roller, ensuring complete coverage without ponding, and respect the overcoat interval before recoating. Clean tools immediately with the recommended solvent while the coating is still wet, as cured material can only be removed mechanically. Store between 5 and 30 degrees Celsius in original unopened packs.

How we position Fosroc Nitocote EP175
Nitocote EP175 occupies the high-build, chemical-resistant interior coating niche in the Fosroc range. It pairs naturally with Nitoprime 25 as its primer and can overcoat Fosroc epoxy screeds, while sitting alongside the wider Nitocote epoxy family (such as Nitocote EP405, the water-based potable-water-contact grade, and EPS/EPU variants) and Fosroc’s Nitoflor epoxy flooring screeds for heavier-duty floors. Where UV stability or exterior exposure is the priority, a polyurethane Fosroc option is the more appropriate route. Against the broader Indian market, credible alternatives include Sika (Sikagard and Sikafloor protective and flooring coatings), MBS (Master Builders Solutions, the former BASF MasterProtect/Ucrete lines), Dr. Fixit (Pidilite) protective and floor coatings, and STP epoxy coating systems. Buyers should compare on verified solids content, film build, chemical-resistance schedule, primer compatibility and on-site pot life at local temperatures rather than headline price alone. As an authorised Fosroc distributor and applicator, Space Arc Engineering supplies genuine Nitocote EP175 with the correct primer and application guidance across Delhi NCR and Pan-India.
