VOC compliant primer
This is high in chemical and abrasion resistance for a variety of substrates. VOC compliant primer has been designed to function as a high performance, one component, and moisture cure urethane primer system, designed for use on steel, aluminum, and stainless steel, galvanized metal, wood and concrete. Its low viscosity allows it to penetrate into porous surfaces, leaving a bubble-free coating. Working time is adjustable by selective addition of catalyst. It also exhibits a low sensitivity to substrate moisture, leaving only minimal bubbling when applied to damp surfaces.
VOC compliant primer is an excellent coating choice for industrial high traffic aisle ways or work cells and warehousing sealer. VOC compliant primer 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.
One year in unopened original containers at 40-90Âº F. Normally, containers should be used within one week after opening unless resealed with nitrogen blanket.
Penetrates and seals the surface, leaving a smooth, pinhole and bubble-free coating

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. Prime with VOC compliant primer.
Stainless steel: Solvent wipe, scuff sand or abrasive blast. Prime with VOC compliant primer.
Steel: Remove all rust, mill scale, and foreign matter. Solvent wipe to remove all oils and grease. Sand blasting is best â€“if possible. Prime with VOC compliant primer.
Aluminum: Solvent clean to remove all oil and grease. Sand surfaces with 120-180 grit sandpaper. Prime with VOC compliant primer.
Concrete: Laitance, curing compounds, concrete contaminants must be removed. Shot-blast or acid etch areas to be coated. Prime with VOC compliant primer.
Stir contents of container prior to application.
Product does not require catalyzation. *Refer to table below.
Add 10% MEK for best adhesion results in all cases. This can be added before packaging or at job site.
To apply VOC compliant primer:
Apply coating as uniformly as possible with a 1/4″ nap roller.
Avoid excessive back rolling and cross rolling, this will lessen the chance of bubbling.
This product is not recommended for immersion service, unless used with a topcoat.
Do not apply this product at ambient or floor temperature below 15Â°F or over 90Â°F or if the relative humidity is above 95%.

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 VOC compliant primer remain dry. Containers that have become contaminated with moisture should not be subsequently sealed; otherwise a hazardous increase in pressure may result.
Freshly manufactured VOC compliant primer 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 VOC compliant primer in carefully sealed containers or under a dry nitrogen atmosphere during handling VOC compliant primer 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.
