Dow 890 SL Self-Leveling Silicone Concrete Joint Sealant - 50 Gallon Drum

Dow 890 SL Silicone Concrete Joint Sealant (formerly Dow Corning 890 SL Silicone Concrete Joint Sealant) is a one-part, cold-applied, easy-to-use, self-leveling silicone material that cures to an ultra-low-modulus silicone rubber upon exposure to atmospheric moisture. Dow 890 SL is a silicone sealant that is pefect for concrete and concrete to asphalt pavement joints and for use in new construction, repair or remedial applications. Dow 890 SL Silicone Joint Sealant can be used to seal irregularly shaped and spalled joints and has many years of staying power. The cured silicone rubber remains flexible over the entire temperature range expected in pavement applications. Dow 890 self-leveling sealant does not need tooling, can be extruded from -20 to 120ºF and flows into irregular joint widths easily. Movement capability: 100% extension and 50% compression. Dow 890 SL is an utra-low modulus, fuel resistant, weather and UV resistant silicone sealer. Refer to Dow form number 62-207 for more information. Dow 890 SL sealant can be cold applied and is ready to use as supplied. Sealant heating or any form of special preparation is not needed. Unprimed adhesion-primer is not required for Portland cement concrete and asphalt which results in labor and material savings. Dow 890 SL sealant will have a skin-over time of one hour or less at standard conditions allowing roadways to quickly be opened to traffic.
