DC-902-RCS Two Part Silicon Sealant

DC-902-RCS Two Part Silicon Joint Sealant

The “DC-902-RCS” Rapid Cure Silicon Joint Sealant is a self leveling, cold applied, rapid cure, two part sealant, applied through a special purpose twin barrel application gun – easy and quick to install, ultra low modulus, 100% silicone rubber sealant designed to seal expansion joints that experience both thermal opening and closing plus shrinkage, together with vertical movements due to traffic loadings. This rapid curing feature is achieved by its two part mix and thus not reliant on atmospheric moisture for the curing process. A primer is recommended.
