UNSPSC 13101715: Natural polyisoprene NR

UNSPSC 13101715 Natural polyisoprene NR is a Commodity code that in state and local procurement covers polymer concrete overlays, epoxy deck sealers, hot-poured joint sealants, and penetrating concrete treatments for pavement and airfield infrastructure repair. Recent solicitations show state and county transportation agencies—primarily departments of transportation and airport authorities—procuring these materials as components of pavement rehabilitation, joint sealing, and concrete repair projects rather than as standalone raw polymer inputs. The code appears to span both premixed sealant systems delivered in ready-to-apply form (such as Sikasil 728 RCS silicone sealant in cartridge kits and hot-poured joint sealant in block form) and field-applied concrete overlay and deck treatment products, with state transportation departments, county road authorities, and airport operators as the primary buying bodies. Issuers include the State of Maine Department of Administrative and Financial Services (establishing statewide master agreements for deck seal and epoxy polymer concrete), the Texas Department of Transportation (soliciting individual sealant kits for bridge applications), Collin County and other Texas counties (procuring liquid asphalt products for road construction under IFB), and airport departments in Georgia, Florida, and Illinois (requesting joint sealing, crack sealing, and pavement rejuvenation services).

Activity clusters in the Texas region (Maine, Texas, and California) with secondary activity in Georgia and Florida. Recent representative opportunities include the State of Maine RFQ 17A26041300000000000259 for deck sealant systems and epoxy polymer concrete (posted 1 July 2026, due 15 July 2026), the Texas Department of Transportation solicitation 601340000066332 for Sikasil 728 RCS silicone sealant for bridge joints (posted 26 June 2026, due 26 June 2026), Illinois Department of Transportation District 5 emergency procurement 26494DOTFINADB52653 for hot-poured joint sealant (posted 5 June 2026, due 10 June 2026), and Dane County, Wisconsin RFB 2026RFB036PR for no-box hot-pour sealant (posted 5 March 2026, due 2 April 2026). Airport pavement and taxiway rehabilitation projects—such as Hartsfield-Jackson Atlanta International Airport's airfield repairs (posted 12 June 2026) and Okaloosa County, Florida's taxiway rehabilitation (posted 22 April 2026)—represent growing secondary activity. A mismatch exists between the code's nominal name (natural polyisoprene) and the actual scope of recent solicitations, which emphasize synthetic epoxy, silicone, and polyester-based sealant systems rather than natural rubber compounds; practitioners should verify material specifications in bid documents rather than rely on the code designation alone.
