• All Ucrete flooring types are very low emission and meet all emission requirements for closed flooring systems in Europe, including AgBB in Germany, Afsset in France where they are certified A+ for VOC emissions (cleanest rating), and M1 in Finland. 

• For more information please contact your local BASF representative.

• Ucrete UD200 is odorless from the mixing stage until the coating is fully cured. 

• This is confirmed by a study by Campden Technology Ltd.

• According to the specifications, Ucrete UD200  primed can be installed and ready for service in as little as 12 hours. 

• Combined with the absence of odor and harmful emissions, this makes it an ideal solution for renovating floors in the food industry.

• The polymeric component of Ucrete UD200 has a softening point above 130°C.

• According to the specifications, Ucrete UD200 can withstand a constant temperature of 130°C and short-term spills of liquid at a temperature of +150°C.

• Properly installed, Ucrete UD200 can withstand regular spills of boiling water, hot oil, and grease.

It has an extremely high resistance to various chemicals used in the food and chemical industry, for example:

Note

There may be some staining or discoloration of the coating due to exposure to chemicals, depending on the nature of the spill, duration, and frequency of cleaning of the premises.

• Ucrete UD 200 has a high strength and low modulus of elasticity, which allows the coating to withstand significant shock loads. 

• Any material can be destroyed, and after significant impacts, chips can form on the surface of the coating. 

• But at the same time, the coating does not crack and does not exfoliate from the base.

• Ucrete industrial floors are extremely resistant to residual moisture in the substrate and can be laid directly on concrete 7 days after pouring, or on good quality old concrete with a high moisture content, without the need for special primers. 

• The presence of a working waterproofing is necessary.

• This allows you to carry out construction work as quickly as possible, as well as carry out repair work without waiting for the complete drying of the concrete base. 

• An epoxy based waterproofing membrane should not be used directly under the coating, as it does not withstand significant temperatures and reduces the thermal stability of the coating as a whole.

• It is very important to eliminate and repair cracks in the concrete floor with fast curing mortars.

• The Ucrete UD200 system is certified for use in facilities using a HACCP food safety system. 

• Ucrete UD200 is easy to clean with standard chemicals and cleaning equipment.

• Coating cleanability tests conducted by Campden Technology Ltd on Acinetobacter Calcoaceticus and Listeria Monocytogenes concluded that “ Ucrete UD200 cleanability is comparable to food grade materials such as plastic and stainless steel.”

Instructions for use UCRETE UD 200

Foundation Requirements

• Ucrete UD200 is used in the Ucrete flooring system on all types of mineral substrates.

• The most common types are: new or old concrete bases, self- leveling cement masses. 

• Not recommended for use on cement-sand screeds (DSP).

• The maximum allowable base slope when using Ucrete UD200 is no more than 5%.

• The use of this material without a primer is not recommended.

• Recommended primers: Ucrete Primer FS, Ucrete Primer SC, Ucrete MF scratch coat.

 

Applying primer to concrete floor

 

• For material compatibility and system options, please contact your local BASF representative.

• Along the perimeter of all enclosing structures (walls, columns), utilities (trays, ladders, pits), as well as all types of seams, technological "anchor" cuts should be organized. 

• These cuts are filled simultaneously with the application of a layer of Ucrete UD200 by the material itself.

• The width and depth of the cuts must be at least twice the thickness of the base layer (for example, the base layer of Ucrete UD200 is 6 mm thick, respectively, the technological cuts should be 12x12 mm). 

• Drawings of junctions and seams are available upon additional request.

• Resin coating work using Ucrete UD200 on conventional concrete must be carried out in accordance with the technology of the selected Ucrete coating system.

• Substrate requirements are set out in more detail in the technical data sheets for primers used in conjunction with this material and are required information when planning Ucrete floor coverings.

Foundation preparation

• The recommended methods for preparing the base are shot blasting or milling.

• The most optimal method of preparing the base is selected depending on its condition, design, existing defects, expected operational impacts and the selected coating system.

• It must be remembered that the mechanical preparation of the base is used not only to remove contaminants, but also to increase the adhesion of the coating. 

• The more textured the surface is obtained as a result of processing, the higher the adhesion of the coating, therefore, its higher resistance to dynamic loads and longer service life.

• Before applying a coat of Ucrete UD200, a properly primed substrate surface should have a clearly visible polymer film.

   

 

• The primed surface must not be sticky or greasy.

•  There should be no visually visible pores on the surface.

• On the primed surface, the presence of contaminants is unacceptable, such as: traces of fuels and lubricants, various oils, fats, various finishing materials, dust, etc.

• During the coating process , it is necessary to carefully observe the interlayer intervals between the various layers. 

• The maximum and minimum overcoat intervals between Ucrete UD200 and primer coats are given in the technical data sheets for the respective primer materials.

Application conditions

• The temperature of the base, during the application of the material, should be at least +5°C and not more than +25°C (it must be remembered that sometimes the temperature of the base can be lower than the air temperature by 3-4 degrees). 

• It is unacceptable within the same working area, the presence of areas with a large difference in base temperature (some factors can lead to this phenomenon, for example, sunlight, various equipment in the room, temperature processes in adjacent rooms, etc.). 

• The base temperature is most easily measured with a pyrometer (non-contact infrared thermometer).

• The substrate temperature must be 3°C above the dew point. 

• The "dew point" is the air temperature at which condensation forms in a room. 

• It depends on the air humidity in the room and is determined according to the calculation table (see Appendix "Dew Point Calculation Table").

• The air temperature at the construction site must be at least +5°С and not more than +25°С. 

• The presence of drafts is highly undesirable - this can lead to surface defects: bubbles, ripples, shagreen, sticky areas.

• Relative humidity at the site, less than 50% can lead to an increase in the curing time.

• The temperature of the material components should be around +20°C. 

• At a high temperature on the object, it is desirable to have a material temperature of about +15°C, and at a low temperature on the object, on the contrary, it is desirable to have a material temperature of about +25°C.

• It must be remembered that the temperature of the material and base, humidity and air temperature directly affect such material properties as viscosity (fluidity), pot life, polymerization time, surface appearance and the presence / absence of various defects.

Material preparation and application

• The material consists of four components, which are in a carefully selected ratio.

• Partial use of the packaging is not allowed. 

• If this rule is not observed, the appearance of multi-colored, shagreen, greasy film on the surface, residual stickiness or a change in the physical and mechanical properties of the layer may occur.

• To prepare the composition, it is necessary to open containers with components, mix using a mixing station (such as Collomix Collomatic XM2 650, Hover Trowel HT-QB-10-C or similar) or a manual two-rotor mixer (Festool MX 1600/2 EQ DUO DOUBLE, Collomix Xo55Duo Power or similar).

 

• "Part 1", "Part 2" and "Part 4" for 20-60 seconds. (at +20°C), then pour in the dry mixture "Part 3" and mix again for 3-4 minutes until smooth. 

• Pay particular attention to the fact that poorly mixed components and lumps of the dry mixture do not fully enter into a chemical reaction.

• The chemical reaction between the components is exothermic (occurs with the release of heat, which reduces the lifetime of the composition), so the volume of the mixed material must be linked to the number of stackers, the speed and method of application, and the temperature at the object. 

• Every minute that a mixed set of material ("Part 1" + "Part 2" + "Part 3" + "Part 4") is in a large volume (mixing vessel) reduces the pot life and, therefore, the processing time of the material.

 

Ucrete UD 200 preparation for mixing polyurethane coating

 

• After preparation, Ucrete UD200 is poured onto the primed substrate as soon as possible and distributed manually using a metal trowel, rule and guides.

• Not later than 5 minutes after the distribution of a set of material, it is necessary to process (smooth down) the laid layer with a metal trowel. 

• It is possible (optional) to lightly roll with a roller, with synthetic pile, to achieve uniformity in color and texture.

 

• When spreading the layer, and especially when processing the material, it is necessary to carefully monitor the life of the material, since the viscosity of the material gradually increases and at the end of the life the tool marks will leave visible irregularities on the surface of the coating.

• When joining two sets of material later than after 7-10 minutes (at a temperature of +20ºС), a visible border may form.

• The application of the material should begin from the wall opposite the exit. 

• In rooms with complex geometry, we recommend that you think over the schedule and work plan for laying in advance.
