Use of SOF-Rod limits the depth of the sealant and prevents excessive sealant use. It also acts as a barrier to the flow of sealant through the joint, helps prevent 3 point bonding, and forces the sealant to take a more optimum shape prolonging sealant service life.

SOF Rod is composed of a bi-cellular polyolefin foam. Bi-cellular polyolefin foam is compatible, both physically and chemically, with most cold applied sealants. Compatibility of sealants in contact with backings can be evaluated according to ASTM 1087 test Method C.
