MC-DUR 260

• PRODUCT DESCRIPTION:

MC-DUR 260 is a 4-component polyurethane trowel applied in thickness of 6-12mm screed. For industrial application and repairing system in matt anti-skid finish offering versatility in performance, aesthetics and economics.

• PRODUCT PROPERTIES:

➢ Anti-skid surface for safety.
➢ Resists bacterial growth; fungi, mold and mildew.
➢ Easily cleaned and maintained smooth seamless surface.
➢ High-density systems with maximum wear, abrasion and impact resistance.
➢ User-friendly, no solvent odour during installation.
➢ One of the fastest “turnaround time” polymer modified product which reduces cost.
➢ High temperature resistance up to 130°C at 12mm thickness.
➢ Seamless without joints for optimum sanitation and hygienic finish.

• AREAS OF APPLICATION:

Ideal area of application includes:
➢ Hygienic floor for kitchen, wet food, beverage processing and packaging plants.
➢ Chemical resistance flooring for chemical process, containment area and wash down rooms.
➢ Thermal shock resistance flooring for freezers, refrigerators, and oven installed spaces. Mechanically durable flooring for loading docks and warehouses.
➢ Anti-skid finish for safety in oily / slippery service condition.

• CHEMICAL RESISTANCE:

 MC-DUR 260 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.

• APPLICATION ADVICE:

➢ Surface requirement & preparation:
– Suitable substrates are concrete or modified polymer screeds with a minimum compressive strength of 25N/mm² and pull-off strength of 1.5N/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, 8mm(wide) x 8mm(deep), at all edges, bay joints columns, doorways, and drains to facilitate mechanical bonding.

➢ 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 260 within its pot life.
– Spread the composite matrix to thickness of 6-12mm and consolidate with steel trowel to the correct depth as desired. Immediately release any traped air by spike rolling.
Temperature: MC-DUR 260 should not be applied on material or floor temperatures below 10°C. Temperatures should not fall below 5°C in the first 24hours after application. MC-DUR 260 is not designed for immersion.

➢ Service temperatures:
– At 6mm of thickness, it can withstand temperatures ranging from -25°C to +100°C.
– At 9mm of thickness, it can withstand temperatures ranging from -35°C to +115°C.
– At 12mm of thickness, it can withstand temperatures ranging from -45°C to 130°C.

➢ Substrate movement: All moving joints must be carried through MC-DUR 260 and properly sealed. Construction joints and cracks may be covered but if substrate movement occurs, MC-DUR 260 will reflect the cracks.

➢ Cleaning: Clean all tools with acetone, xylene 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.
