PRODUCT DESCRIPTION:
MC-DUR 230 is a 4-component, self-leveling, anti-slip, matte-finish polyurethane floor coating. The product has long-term chemical resistance at high temperatures, good resistance to thermal shock and abrasion. In addition, the product can be used as a direct coating on old or worn polyurethane floors.
PRODUCT PROPERTIES:
- Excellent chemical resistance.
- High temperature resistance up to 80°C.
- Resists bacterial growth; fungi, mold and mildew.
- High-density systems with maximum wear, abrasion and impact resistance.
- Maintains a smooth, hard and durable surface over time.
- Creates a seamless finish, making cleaning quick and easy.
- User-friendly, no solvent odour during installation.
- One of the fastest “turnaround time” polymer modified product which reduces cost.
AREAS OF APPLICATION: Wide range of applications, including:
- Floors of seafood factories, food factories, breweries, beverage factories, etc.
- Floors of kitchen areas, specialized cleaning areas, areas requiring high chemical resistance, chemical warehouses.
- Heat shock resistant floors for cold storage areas, freezers, etc.
- Floor areas requiring high mechanical strength and other stability.

APPLICATION ADVICE:
Surface requirement & preparation:
- Suitable substrates are concrete or polymer modified mortar with a minimum compressive strength of 25 N/mm² and a tensile strength of > 1.5 N/mm².
- Substrate to be coated must be clean, free from dust, oil, water, paint residues, loose constituents or any contaminants. Make use of a concrete surface planer, grit blasting, surface grinding or other mechanical means until a flat, rough profile is evident. Prepare grooves, 5mm (wide) x 5mm (deep), at all edges, column joints, doors and membrane end areas to ensure the membrane does not peel or pop.
Mixing: Shake the containers of components A and B well before use. First put component A into a clean mixing vessel and stir in component D MC-DUR Color (pigment) and stir. Then add component B and continue stirring. Use a slow speed mixer and stir the mixture for about 1 minute until a homogeneous mixture is obtained, without any streaks of color. Then add the aggregate (component C) to the pre-mixed plastic mixture and continue stirring until the mixture is homogeneous. It is necessary to use a mixer to mix the plastic components with the aggregate together. Mixing time depends on the temperature of component C. At a temperature of 18 – 22°C, mixing time can be up to 3 minutes.
Application:
- Apply MC-DUR 230 within its pot life.
- Spread the composite matrix to thickness of 3-6mm and consolidate with pin rake or notched squeegee set to the correct depth. Immediately release any trapped air by spike rolling.
Temperature: MC-DUR 230 should not be applied on material or floor temperatures below 10°C. Temperatures should not fall below 5°C in the first 24 hours after application. MC-DUR 230 is not designed for immersion.
Service temperatures:
- For 3mm floor thickness, it can withstand temperatures ranging from -5°C to +80°C.
- For 6mm floor thickness, it can withstand temperatures ranging from -25°C to +100°C.

| Full cure. (days) | 7 | 5 |
Chemical resistance: MC-DUR 230 will resist spillages of :
- Dilute and concentrated acids: hydrochloric, nitric, phosphoric and sulphuric.
- Dilute and concentrated alkalis, including sodium hydroxide to 50% concentration.
- Most dilute and concentrated organic acids.
- Fats, oil and sugar.
- Mineral oils, kerosene, gasoline and brake fluids.
- Most organic solvents.
Cleaning:
Clean all tools with Washing Thinner or other solvents before the material hardens. Small unreacted Part B in container is to be decontaminated with a 5% solution of washing soda (sodium carbonate) prior to disposal. After material has set it is virtually impossible to get off and will only wear off over time.
Maintenance:
Regular cleaning and maintenance will prolong the life of all resin floors, enhance the appearance and reduce the tendency to retain dirt.
