UNSPSC 13101707: Isobutylene isoprene IIR/XIIR

UNSPSC 13101707 Isobutylene isoprene IIR/XIIR is a Commodity code that encompasses synthetic rubber materials and specialty polymers used in pavement sealants, joint sealing compounds, and protective coatings for transportation infrastructure. State and local governments procure these materials primarily as components in deck sealant systems, joint sealers, and epoxy polymer concrete overlays for highway, bridge, airport, and parking structure rehabilitation. Issuing bodies include state departments of transportation, county public works departments, municipalities, airport authorities, and educational institutions. The recent solicitation activity shows procurement concentrated among transportation infrastructure owners performing preventive maintenance and capital repairs: the State of Maine DOT is establishing a master agreement for deck sealants and epoxy polymer concrete products; Texas DOT is procuring Sikasil 728 RCS silicone joint sealant for bridge applications; and multiple regional authorities (Wayne County Airport in Georgia, City of Urbana, Dane County, Port Authority of New York and New Jersey) are sourcing hot pour joint sealants, crack-sealing compounds, and pavement rejuvenation materials. Geographic activity clusters in Texas, Georgia, California, Florida, Wisconsin, Maine, and Illinois, reflecting year-round infrastructure maintenance cycles and regulatory compliance drivers in high-traffic corridors.

The State of Maine Department of Administrative and Financial Services, Office of State Procurement Services issued RFQ 17A26041300000000000259 on July 1, 2026, due July 15, 2026, for deck sealant systems and epoxy polymer concrete products in penetrating concrete sealers, single- and double-layer treatments, and epoxy polymer overlay kits, establishing a master agreement for all state departments with estimated annual usage of 400 gallons of penetrating sealers, 400 gallons of single-layer treatments, 5,000 gallons of double-layer treatments, and 2,000 kits of epoxy polymer concrete through August 30, 2031. Texas DOT issued RFQ 601340000066332 on June 26, 2026, due same day, for Sikasil 728 RCS silicone sealant in 40 oz sausage kits for the Lubbock District bridge joint applications. Collin County, Texas issued IFB 2026-277 on June 23, 2026, due July 16, 2026, for liquid asphalt products including CRS-1, CRS-2P, CSS-1, MC and RC grades in quantities up to 8,000 gallons per product type, with an estimated annual contract value of $100,000. Dane County, Wisconsin issued RFB 2026-RFB-006 on February 27, 2026, due February 23, 2026, for hot pour sealant conforming to ASTM D3405/AASHTO M301 with reclaimed rubber content. These opportunities signal steady demand for specialty sealant materials driven by infrastructure asset management budgets, regulatory maintenance schedules, and weather-dependent repair cycles in climates requiring seasonal pavement conditioning.
