US 2K4  ESD flooring adhesive is a patented pressure sensitive conductive liquid adhesive designed for static control carpet tiles and  esd vinyl floor tile.  Usage of this product allows excellent long term results when installing esd solid vinyl flooring tiles over non-porous VCT in a "tile over tile" application. In addition, this conductive adhesive allows the removal and subsequent replacement of damaged or worn esd flooring overlayments while maintaining it's reliable long term permanent tack.  This adhesive contains no VOC's, is solvent free, non hazardous, provides excellent plasticizer resistance and is relatively odor free and easy to work with. 

Application of this adhesive determines the bonding mechanism, allowing competent flooring contractors to achieve either a permanent or releasable bond to a variety of flooring substrates including (but not limited to): Concrete (that is properly dried and cured), raised flooring access panels (steel and most composite materials), VCT and other substrates.   Bond strength testing of materials is recommended prior to full scale usage of this product as it is the clients responsibility to determine the suitability of all materials for use in their specific applications.

 All flooring substrates must be clean, level, dry, free of dust, dirt, wax or any other material that may interfere with the overall bond strength of this product. This adhesive is photosensitive if exposed to ultraviolet light and will loose it's tack.  Maintain floor covering material and adhesive at a minimum temperature of 65 Degrees F. 48 hours prior to, during and after installation. 

Do not use this adhesive if excessive hydrostatic pressure exist. Test concrete surfaces for vapor emission per ASTM F-1869-98 prior to use using calcium chloride test kits identical or similar to those provided by Vaprecision.   This adhesive is designed for use on concrete surfaces exhibiting a vapor emission rate of <3.0 lbs per 1000 SF over a 24 hour period.

Stir adhesive prior to usage as some settling of the conductive fiber (used in this product) may occur. This adhesive is not recommended for use over existing cutback carpet adhesive or it's residue.  Cutback adhesives must either be encapsulated or removed prior to usage of this material.

For releasable static control carpet tile installation on non-access substrates: Apply this adhesive with a 1/16 x 1/16 x 1/16 Square notch trowel.  Adhesive must be full spread to achieve complete coverage.  Do not use a roller to spread adhesive.  For a releasable bond (leaving residue on the substrate but not on the back of the carpet tiles), allow the adhesive to "dry" prior to putting carpet tile in place.  The average drying time on porous concrete is 90 minutes while the average drying time on non-porous substrates (like VCT) is approximately 120 minutes.  The adhesive will turn from milky blue to transparent as it dries.  Drying time is somewhat contingent on humidity, temperature and building ventilation. Coverage using this method is approximately 160 square feet per gallon. For increased bond strength (leaving a residue on both the tiles and the substrate) simply place the tiles into the adhesive while wet using the same spread rates as listed above.

For releasable carpet tile installation on raised access flooring substrates: Apply this material using a 1/4" foam roller.  Adhesive should be fully spread over the access floor panels to achieve complete coverage HOWEVER for easy removal of the raised access flooring panels care should be taken to avoid filling seams between panels with adhesive.  Allow the adhesive to "dry"  prior to placement of carpet tiles/  Average drying time for this method is approximately 75 minutes.  The adhesive will turn from milky blue to transparent as it dries. Coverage using this method is approximately 300 square feet per gallon.

For releasable or permanent solid vinyl ESD tile installation on non-access substrates:   Apply the conductive adhesive with a 1/32 x 1/16 x 1/32 U notch trowel.  Adhesive must be full spread to achieve complete coverage.  For a releasable bond (leaving residue on the substrate but not on the back of the vinyl tiles), allow the adhesive to "tack up" prior to installing esd vinyl tiles..  The average drying time on porous concrete is 60 minutes while the average drying time on non-porous substrates (like VCT) is approximately 90 minutes.  The adhesive will turn from milky blue to transparent as it dries.  Drying time is somewhat contingent on humidity, temperature and building ventilation. Coverage using this method is approximately 180 square feet per gallon. For increased bond strength (leaving a residue on both the tiles and the substrate) simply place the tiles into the adhesive while slightly tacky (after drying approximately 10-15 minutes). Use the same spread rates as listed above. In both application methods roll vinyl tiles with a 100 pound vinyl flooring roller immediately following placement of tiles. Roll entire floor again 24 hours after initial install.  This adhesive is sensitive to water and other liquids (such as ESD Wax) for a period of up to 30 days after the initial install. Allow floor to cure prior to use of liquids

For releasable solid vinyl static control tile installation on raised access floors:   Apply this material using a 1/4" foam roller.  Adhesive should be fully spread over the access floor panels to achieve complete coverage HOWEVER for easy removal of the raised access flooring panels care should be taken to avoid filling seams between panels with adhesive.  Allow the adhesive to "dry" completely prior to placement of carpet tiles/  Average drying time for this method is approximately 75 minutes.  The adhesive will turn from milky blue to transparent as it dries. Coverage using this method is approximately 300 square feet per gallon. For increased bond strength (leaving a residue on both the tiles and the substrate) simply place the tiles into the adhesive while wet using the same spread rates as listed above. In both application methods roll vinyl tiles with 100 vinyl flooring rollers upon placement of tiles.

• Grounding of flooring is required prior to use of this adhesive.  For more information on grounding a static control floor please visit: How to ground an ESD Floor.

Note: when using with vinyl esd flooring materials appropriate care should be taken to not use excessive quantities of liquids such as strippers cleaners and ESD wax for at least 30 days following installation.

Excessive use of liquids can soften adhesive bond if allowed to accumulate for long periods.
