UNSPSC 13101716: Synthetic polyisoprene IR

UNSPSC 13101716 Synthetic polyisoprene IR is a Commodity code that spans sealant and pavement treatment products for highway, airport, and parking infrastructure maintenance. State and local governments procure this material primarily as deck sealants, joint sealers, crack-fill compounds, and asphalt preservation treatments—products that appear in recent solicitations for concrete pavement repair, airfield rehabilitation, and roadway preservation across multiple jurisdictions.

The issuing bodies soliciting under this code span state departments of transportation, counties, cities, and special-purpose airport authorities.
