Name: SOF庐ROD (PATENTED)
HIGHWAY SEALANT
BACKER ROD
SOF庐ROD is a continuous length of bicellular extruded
polyolefin foam made of a non-absorbing outer skin
and a highly resilient interior net work of both open
and closed cells that does not out gas when ruptured.

COMPATIBILITY
SOF庐ROD is basically an inert material, and therefore compatible both physically and chemically with virtually all known cold applied sealants
including self-leveling types.
INSTALLATION
Verify that the joint is clean, moisture free and clear of obstructions. Select SOF庐ROD in a diameter approximately 25% larger than the joint.
Cut SOF庐ROD to the desired length or dispense directly from the reel. Position SOF庐ROD in the joint at the depth specified by the sealant
manufacturer, engineer, or architect. Press SOF庐ROD uniformly into the joint using a blunt tool. Apply the sealant over SOF庐ROD following the
sealant manufacturer鈥檚 directions.
PRECAUTIONS
Do not puncture, over compress or stretch SOF庐ROD during insertion. Do not use with hot applied sealants. Tests for outgassing of cold applied
sealants shall be made in accordance with ASTM Test Method C 1253. Sealant compatibility should be confirmed by the sealant manufacturer.
Compatibility characteristics of sealants in contact with sealant backings can be determined by ASTM Test Method C 1087.
