Sika® Backing Rod is an extruded polyethylene foam, available in rods with different diameters and lengths. It is easy to use, closed cell, no bond to most sealants and highly compatible with cold applied sealants. It provides a firm backing for joints subjected to hydrostatic pressure. In addition, it is odorless and has excellent water resistance.
It is used as a back up material for cold applied Sika sealants and as a bond breaker, permitting the most efficient joint design. It is packaged with different rod sizes and length.
During the installation of Sika® Backing Rod, it is advised to be careful not to cut or puncture the surface skin. Furthermore, avoid excessive longitudinal stretching of the rod and do not use as a backer, where sealants are heated and applied at a temperature above +70°C. In addition, it is recommended to use the rod which has a diameter of approximately 25 percent larger than the joint width. The included rods length are 8, 10, 15, 20 and 25 millimeters.
