ChemLink SOF ROD Bi-Cellular Backer Rod per foot 3/8''

Chem Link SOF-Rod is a cylindrical, flexible foam rod for use as a sealant backing. SOF-Rod is composed of a bi-cellular material. SOF-Rod may also be used as a gasket or sealing material as per ASTM C 717. These are round rods of various diameters for use with non-sag and self-leveling cold-applied sealants.

Just prior to placing SOF-Rod, clean all joints per the sealant manufacturer's recommendations. Thoroughly remove any concrete form-release agents, curing compound residue, laitance, or any foreign materials. To ensure a good sealant bond, joints must be clean, dry, and free of contamination prior to sealant application. Air compressors used for this purpose must be equipped with traps for the removal of oil and moisture. Proper size selection is important as it controls the depth of the sealant bead and helps prevent three-point bonding.
