Heavy duty polyurethane concrete flooring Description
UCRETE UD200 is a three part polyurethane concrete, designed for application by trowel at thicknesses of 6mm and above.
Uses
UCRETE UD200 floors find their widest use in the food industry. They have a light profiled finish giving an optimum combination of wet / dry slip resistance and ease of cleaning. The choice of thickness is determined by service / cleaning temperatures and severity of traffic.

Application
Substrate quality
Substrates will normally be concrete or polymer modified screeds. Other substrates may be suitable; consult your specialist applicator or your local BASF sales office.
All substrates must be clean and free from dust and loose particles. Concrete and other cementitious substrates must be visibly dry and have a minimum tensile (pull-off) strength of 1.5 N/mm². UCRETE UD200 may be applied to substrates of lower strength but the long-term performance of the floor may be affected. All traces of contaminants, such as oil, fats, paint residues, chemicals, algae and laitance, should be removed.
Preparation of substrate
As with all surface coatings, proper surface preparation is vital to ensure the successful application and performance of UCRETE UD200.
The preferred method of surface preparation is vacuum shot blasting. Other methods, such as air impact hammer (scabbler) - provided that the substrate is not damaged, concrete surface planer, grit blasting, wire brush scarifier, surface grinder, drum sander and flame spaller, can be satisfactory. Chemical methods, such as acid etching, are not reliable and not recommended.
Priming
If the surface quality of the finished UCRETE floor is important for hygiene or aesthetic reasons, the prepared substrate should be primed with PRIMER SC prior to the application of UCRETE flooring.
Mixing and application
Full details of correct mixing and application procedures are given in the UCRETE Application Manual which is available to licensed and specialist applicators only.
Curing
The following table should be used as a guide at 15 to 25°C.
| Foot traffic |
8 hours |
| Light traffic |
24 hours |
| Full traffic and chemical resistance |
48 hours |
Coverage
Coverage is influenced by substrate roughness, porosity and temperature
Chemical resistance
UCRETE UD200 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, oils and sugars
- mineral oils, kerosene, gasoline and brake fluids
- most organic solvents
In many cases resistance is maintained to elevated temperatures even under thermal shock conditions. A maximum service temperature of 120°C at a thickness of 9mm (70°C at 6mm thickness) should be observed.
Detailed information on chemical resistance is available from BASF Middle East.
Cleaning
Cleaning of plant and equipment should be undertaken well away from the application area. Xylene may be used to clean equipment, tools and spillages. In the case of spillages, excess material must first be absorbed onto sawdust or other disposable absorbent medium. Use correct handling procedures with solvents and take care to avoid any accidental spillage or splashes onto coated surfaces.
Part 2 containers may contain small amounts of unreacted diisocyanates (MDI). Therefore they must be decontaminated with a 5% solution of soda ash (sodium carbonate or washing soda) prior to disposal as building waste.
Maintenance
Regular cleaning and maintenance will prolong the life of all resin floors, enhance the appearance and reduce the tendency to retain dirt.
Specialised floor cleaning equipment and chemicals are ideally available and the suppliers are able to offer advice on appropriate cleaning regimes. Consult your specialist applicator or BASF Middle East office for advice.
Storage
All parts of UCRETE UD200 should be stored under cover and free off the ground. Storage conditions should be dry, above 5°C and below 30°C. Parts 1 must not be allowed to freeze.
Health and safety
Appropriate health and safety advice can be found in the Material Safety Data Sheets.
Users are advised to wear gloves and eye protection when mixing and applying UCRETE UD200.
Safety precautions
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until products is fully cured or dried). Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use and dispose off empty containers correctly.
Note
Field service, where provided, does not constitute supervisory responsibility. For additional information contact your local BASF representative.
BASF reserves the right to have the true cause of any difficulty determined by accepted test methods.
Quality and care
All products originating from BASF's Dubai, UAE facility are manufactured under a management system independently certified to conform to the requirements of the quality, environmental and occupational health & safety standards ISO 9000, ISO 14001 and OHSAS 18001.
