Dow 888 Silicone Joint Sealant - 50 Gallon Drum

Dow 888 silicone sealant (formerly Dow Corning 888 silicone sealant) is a one-part, non-sag silicone joint sealant for Portland cement concrete pavement joints. Dow 888 cures to a low-modulus silicone rubber upon exposure to atmospheric moisture and can be applied over a wide temperature range. Dow 888 can be used for concrete to concrete pavement joints. Dow 888 can be used in new construction, repair or remedial applications. Dow 888 silicone joint sealant may be used to seal joints that are not uniform in width provided the movement capability of the sealant is not exceeded. Dow 888 silicone joint sealant may also be used in joints with minor spalling. Dow 888 silicone sealant is low-modulus and weather and UV resistant. Primer is not required for bonding to Portland cement concrete. For optimum Dow 888 adhesion, the surface must be clean, dry and frost-free.
