DOWSIL 890-SL Silicone Joint Sealant is a high-performance, one-part, self-leveling silicone sealant engineered for use in concrete and concrete-to-asphalt pavement joints. This ultra-low-modulus, cold-applied material cures upon exposure to atmospheric moisture, forming a flexible, durable silicone rubber that remains elastic even in extreme temperatures from -20°F to 300°F.
Ideal for new construction, repairs, or remedial sealing applications, DOWSIL 890-SL offers excellent movement capability—100% extension and 50% compression—making it ideal for high-traffic environments. It flows easily into irregular joint widths without requiring tooling and provides weatherproof, UV-resistant, and short-term fuel-resistant sealing.
