Sealant Solutions for Airports and Airfields

Protect runways and roadways from severe joint movement and environmental extremes

For joints on demanding airport runways and taxiways, you can trust the proven silicone sealants from Dow. Backed by more than 20 years of silicone construction expertise, Dow’s silicone pavement sealants resist UV radiation, temperature and weather extremes to ensure a durable, long-lasting solution. 

Airfield environments change constantly. Dow has responded to these changing conditions with silicone pavement sealants that are long-lasting and ultra-durable. It works by accommodating thermal movement and engineered to offset interference from traffic loading. The sealant’s durability also meets all requirements for flame resistance according to section 4.4.12 of the SS-S-200E (Jet Blast) code.
