DOWSIL™ 890-SL Silicone Joint Sealant
DOWSIL™ 890-SL Silicone Joint Sealant is a one-part, self-levelling silicone material that cures to an ultra-low-modulus silicone rubber upon exposure to atmospheric moisture. The cured silicone rubber remains flexible from -20 to 300°F. Asphaltic paving materials have low tensile strengths. It is important to use an ultra-low modulus material when sealing these substrates to ensure minimal strain is placed on the asphalt joint face.
