Dow Corning® 888 Silicone Joint Sealant is especially effective for sealing transverse contraction and expansion joints, longitudinal, center line and shoulder joints in Portland Cement Concrete (PCC).

Highways, bridges and airport runways are tough joint sealing applications. To protect the integrity of roadway and airport runway pavement, sealants must:

• Withstand severe horizontal and vertical concrete expansion joint movements
• Handle temperature and weather extremes
• Install easily with a short downtime
• Offer a long service life

Silicone pavement sealants from Dow Corning cure to form a permanently flexible, low- to ultra-low-modulus silicone rubber seal. They can withstand a high degree of movement (+100/-50 percent of the original joint width) with excellent recovery, making them ideal for sealing joints under continuous stress.
