OSI SC-170 Vapor and Acoustical Sound Sealant are specifically designed for reducing sound transmission in all types of wall partitions to maintain specified STC values. Sealant is non-hardening, non-staining and very tacky. It adheres to drywall, wood, metal, masonry, polyethylene and other building materials. SC-170 provides an air tight vapor barrier when used with polyethylene sheeting to help prevent air infiltration and the formation of condensation. SC-170 was developed primarily for commercial construction utilizing light weight cavity walls and floor systems. The sealant is used for unexposed applications at perimeter joints, floor and ceiling runners (either wood or metal), and cut-outs in gypsum board, veneer plaster systems and other areas where a sound rated assembly is required. It can also be used as a buck frame, threshold or bedding sealant when applied to metal or glass surfaces.
