Description
HYREZ-UVR is a paint brush / squeegee / roller applied polyurethane floor coating for industrial use. Highly chemical resistant, with slight flexibility, to give a smooth, low sheen finish whilst still allowing hygienic cleanliness and seamless flooring. Supplied in a variety of colours for use in environments that range from back of house to wash bays, office to walkways, and light processing areas. Organohalogene tested and approved by Thales as part of
the HYREZ range of polyurethanes.

Typical Applications
HYREZ-UVR can be used in food processing plants, cold rooms, canning factories, bottling plants, foot traffic areas and environments where food safety, high chemical resistance, wet areas, and light industrial use are all prerequisites.

Watch Points

• A formal hygienic cleaning procedure is required to keep the surfaces hygienically clean and food safe.
• Polyurethane screeds are not UV stable, however the HYREZ-UVR has a much higher tolerance for UV radiation. Direct and continued exposure to sunlight will still cause discolouration.
• Do not apply in excess of the application thickness as this may cause blistering and surface unevenness.

Directions for Use
Application Conditions: Application temperature should be between 15C and 25C. Employ the use of localized cooling or heating equipment if necessary. Try avoid applying over hot surfaces or previously heated areas. Substrates must have a moisture content of 12% maximum and tensile strength of 1.5 N/mm2 minimum.

Surface Preparation: Surfaces need to be cleaned and flattened or imperfects will show through flow applied
applications. Light grinding to remove all surface defects is recommended. Scabbling and acid etching is not recommended. Anchor grooves are not necessary for HYREZ-UVR.

Priming: Existing polyurethane substrates do not need priming. Prime concrete substrates with MULTI PU PRIMER or MULTI POXY SCREED PRIMER using a trowel and allow to cure for 12 hours to minimize draw in of the HYREZ-UVR into the substrate and prevent pin-holing.

Application: Shake well the resin component to resuspend all the pigments in the liquid. In a bucket, premix the resin and the hardener until mixed together. Then transfer the mix into a roller pan or flat bottom half drum. Using a short pile mohair roller, dip into the pan and roll evenly over the prepared surface. Alternatively pour out the mix onto the floor and squeegee out evenly. Cut in edging using a paint brush. Only mix enough product
that can be applied within 12-15 minutes. Allow to cure for 12-24 hours. Protect the curing floor from damp, condensation, and direct water for at least 24 hours.

Limitations: Do not apply in humidity is expected to be greater than 90% RH, or if the surface temperature is less than 3C above the dew point.
Ensure that the curing temperature never drops below 5C, and do not apply over concrete that is less than 20 MPa compressive strength. Colour variations can occur between batches so apply sections from the same batch of resin. Touching up will always be visible and should be avoided.

Equipment Care
All tools should be cleaned with thinners or xylene immediately after use.
