Put the silicone advantage to work for you

Designed for use on expansion joints, construction joints and crack-control joints in concrete. Dow silicone pavement sealants have several benefits:

Water and debris blocking

Keeps water and incompressible debris out of joints to maintain their function and avoid cracks and prevents freeze-thaw damage.

Resistant

Protects against UV radiation, extreme temperatures and weather conditions.

Long-lasting sealing

Provides long-lasting sealing by accommodating extreme movement (thermal stress).

Excellent recovery

Exhibits excellent recovery characteristics, making them ideal for use in joints that experience a high degree of movement.

Outperform organic alternatives

Silicones offer great UV stability and temperature and weather resistance ensuring a long-life span.

Superior silicone rubber seals

Creates long-lasting, flexible, low to ultralow-modulus, high-elongation silicone rubber seals capable of withstanding 100 percent extension and 50 percent compression of the original joint width.

Silicone joint sealants available in varying product options

Easy-to-install one-part sealants or rapid-cure two-part sealants
Ultra-low modulus sealants for joints in concrete and asphalt pavements that place very little stress on the bond line
Self-leveling sealant to increase efficiency
