Polyurea Single Component
Polyurea Single Component is a VOC compliant top coat, high in chemical and abrasion resistance for a variety of substrates. Polyurea Single Component has been designed to function as a high performance, one component moisture cure urethane top coat system, designed for use on steel, aluminum, and stainless steel, galvanized metal, wood and concrete leaving a bubble-free coating. Working time is adjustable by selective addition of catalyst. It also exhibits a low sensitivity to substrate moisture, when applied to damp surfaces.
Polyurea Single Component is an excellent coating choice for industrial high traffic aisle ways or work cells and warehousing sealer. Polyurea Single Component can also be used as an interior coating for wood flooring or furniture. Also used for roofing, decking, truck bed liners, pipeline, and tank coatings.
ORACR 42 has been independently tested and certified to meet or exceed all the requirements of ASTM D-6083 Standard Specification Liquid-Applied Acrylic Coating used in Roofing.
Standard colors are black and dark gray.
For non-skid application various products can be added for both roll on or spray applied versions. To spray apply with the non-skid additive, please call for proper application equipment needed.
One year in unopened original containers at 40-90° F. Normally, containers should be used within one week after opening unless resealed with nitrogen blanket.
Penetrates and seals leaving a smooth, pinhole and bubblefree coating
Excellent adhesion to a variety of substrates
Good physical properties
Outstanding stability at low temperatures

Previously painted surfaces: Solvent clean to remove all oils, grease and wax. Remove all rust and damaged paint. Feather edge the repair areas. Fill and putty as required. Sand all areas to be painted with 120-180 grit wet or dry sandpaper.
Stainless steel: Solvent wipe, scuff sand or abrasive blast.
Steel: Remove all rust, mill scale, and foreign matter. Solvent wipe to remove all oils and grease. Sand blasting is best â€“if possible.
Aluminum: Solvent clean to remove all oil and grease. Sand surfaces with 120-180 grit sandpaper.
Concrete: Laitance, curing compounds, concrete contaminants must be removed. Shot-blast or acid etch areas to be coated.

Product does not require catalyzation.
-To apply Polyurea Single Component
Apply coating as uniformly as possible with a Â¼â€ nap roller.
Avoid excessive back rolling and cross rolling, this will lessen the chance of bubbling.
Spray apply as you would high quality paint.
-To apply Polyurea Single Component
This product is not recommended for immersion service.

Handling and Storage
The reaction of isocyanates with water leads to the formation of insoluble ureas and carbon dioxide gas which gas which can result in pressure buildup inside closed containers. Therefore, extreme care must be taken to ensure containers used for Polyurea Single Component remain dry. Containers that have become contaminated with moisture should not be subsequently sealed; otherwise a hazardous increase in pressure may result. Freshly manufactured Polyurea Single Component is an amber liquid. Sedimentation is usually due to contamination from atmospheric moisture or to dimer formation. Reaction from atmospheric moisture can be prevented by storing Polyurea Single Component in carefully sealed containers or under a dry nitrogen atmosphere during handling Polyurea Single Component must be carefully resealed after each sampling. A small amount of finely divided insoluble solid in the product does not usually cause difficulties in handling or product performance. However, if necessary, the liquid product may be filtered through a suitable inline filter. It is suggested that the filter vessel be of stainless steel with a suitable polypropylene filter bag. The lines should be heated and blown clear with nitrogen after use.
