Product Overview

MC-Floor WB is MC-Bauchemie water-borne epoxy floor sealer and primer — the environmentally responsible alternative to solvent-borne epoxy floor sealers in the MC-Floor range for applications where low VOC emissions, odour control, and environmental safety during application are required alongside the epoxy performance characteristics of good adhesion, hardness, and chemical resistance. The distinction between MC-Floor WB and the solvent-borne MC-Floor PU or solvent-borne epoxy floor systems lies not in the final cured film performance (which is broadly similar) but in the application phase: solvent-borne floor systems release large quantities of volatile organic solvents during application and initial curing (24 to 48 hours), creating a fire hazard (solvents are flammable), a health hazard (solvent vapours at high concentration cause acute headaches, nausea, and long-term neurological effects), and an occupational exposure limit exceedance that requires evacuation of the building or floor during and after application; MC-Floor WB uses water as the carrier, reducing VOC content to below 50 to 100 grams per litre (versus 300 to 600 grams per litre for solvent-borne epoxy systems), allowing application in occupied or recently vacated buildings with minimal disruption and no fire hazard. The application niche for MC-Floor WB in the Indian market is large: hospitals and healthcare facilities (where solvent odour is unacceptable to patients and clinical staff and open flames from solvent-borne coatings are a safety issue near medical gas lines), pharmaceutical GMP production areas, food processing facilities (regulatory compliance for food-contact area floor coatings limits VOC), office buildings and educational institutions, and any enclosed space where ventilation is limited. Space Arc Engineering supplies MC-Floor WB for flooring contractors, maintenance teams, and facility managers in Ghaziabad, Delhi NCR, Noida, and Uttar Pradesh.

Applications

• Dust-proof floor sealing of concrete in hospitals and healthcare facilities — application of MC-Floor WB as a dust-proof sealer to the concrete floors of hospital utility rooms, service corridors, plant rooms, and non-clinical areas where the concrete floor must be sealed to prevent concrete dust (a respiratory irritant) and to provide a cleanable surface that can be mopped with disinfectants; the low VOC formulation allows application in areas adjacent to patient wards, operating theatres, and clinical areas without the odour complaints and evacuation requirements of solvent-borne floor coatings; a single coat of MC-Floor WB penetrates the concrete surface and forms a hard, smooth, sealed surface that can be maintained with standard hospital floor cleaning protocols
• Primer coat for MC-Floor system topcoats in enclosed environments — use of MC-Floor WB as a primer coat under MC-Floor PU or other MC-Floor topcoat systems in enclosed spaces where the first coat must be a low-odour, low-VOC waterborne product to allow the building to be occupied or semi-occupied during the priming stage, with the topcoat applied after the building has had adequate ventilation; this staged application protocol — waterborne primer first, solvent-borne or 100 percent solids topcoat second — reduces the total solvent emission during the project and is increasingly required by hospital facility managers and pharmaceutical plant HSE coordinators when specifying floor coating projects
• Light-duty floor sealing in pharmaceutical GMP manufacturing areas — application of MC-Floor WB as a stand-alone floor sealer in pharmaceutical manufacturing suites and packaging halls classified as GMP Grade C and D (lower-cleanliness-grade production support areas) where the floor is required to be smooth, non-porous, cleanable, and resistant to pharmaceutical process chemicals (dilute acids, alkalis, and process solvents at ambient temperature) but where the production schedule does not permit the 48 to 72 hour floor-out-of-service period required for heavy-duty solvent-borne epoxy systems; MC-Floor WB achieves light foot traffic in 8 to 12 hours and can be put into service within 24 hours of application
• Floor sealing in food processing and beverage plants in low-traffic areas — application of MC-Floor WB to the concrete floors of food storage areas, dry ingredient stores, packaging rooms, and staff areas in food processing and beverage production facilities where the floor must comply with food safety and hygiene requirements (smooth, cleanable, resistant to food acids and cleaning agents) and where the low VOC requirement is important because food products or packaging materials are stored in the area and solvent contamination of food contact materials is a compliance issue
• Office building and commercial space concrete floor sealing — application of MC-Floor WB to polished or plain concrete floors in open-plan offices, retail outlets, showrooms, and commercial spaces in the growing Indian preference for exposed concrete floor aesthetics — a single or double coat of MC-Floor WB applied to mechanically ground and polished concrete provides a hard, sealed, low-sheen finish that enhances the natural concrete appearance, eliminates dust, and provides a cleanable surface without the yellowing that occurs with solvent-borne epoxy coatings under UV exposure in spaces with natural light

Key Advantages

• Low VOC content for safe application in occupied and enclosed environments — VOC content below 50 to 100 grams per litre (verify current data sheet) versus 300 to 600 grams per litre for solvent-borne epoxy systems — allows application in hospitals, food processing areas, pharmaceutical facilities, and occupied office buildings without the fire safety issues, health hazards, and extended evacuation periods required for solvent-borne floor coatings; compliance with increasingly stringent VOC regulations and GRIHA and LEED green building rating system requirements for indoor air quality in building projects seeking sustainability certification
• Good adhesion to concrete substrates and compatibility as a primer for MC-Floor topcoats — the water-borne epoxy binder provides adequate adhesive bond to prepared concrete surfaces (minimum 1.5 to 2.0 MPa tensile bond by pull-off test on properly prepared substrate) and forms an effective primer layer for adhesion of subsequent MC-Floor solvent-borne or 100 percent solids epoxy and polyurethane topcoats; using MC-Floor WB as a primer in a two-coat system combines the environmental benefit of low VOC in the first coat with the durability and chemical resistance of a high-performance solvent-borne topcoat
• Rapid return-to-service for production facility and commercial maintenance applications — walk-on capability within 6 to 8 hours at 25 degrees Celsius and light vehicle traffic within 24 hours, enabling maintenance floor sealing projects to be completed overnight or over a weekend in occupied commercial and industrial facilities with minimal disruption to operations; curing time is temperature-dependent — in Indian winter conditions below 15 degrees Celsius, curing slows significantly and 24 to 36 hours may be required for walk-on
• UV stability for spaces with natural light — the water-borne epoxy-polyurethane hybrid formulation (where MC-Floor WB includes a polyurethane component for exterior or UV-exposed applications) or the use of UV-stabilised acrylic-epoxy chemistry provides resistance to yellowing and colour change under natural light exposure, an advantage over standard solvent-borne or 100 percent solids epoxy coatings that yellow progressively under UV — making MC-Floor WB appropriate for office spaces and commercial areas with large windows and direct sunlight on the floor surface
