UNSPSC 13101702: Highly saturated nitrile HNBR

UNSPSC 13101702 Highly saturated nitrile HNBR (Commodity) describes elastomeric sealing and bonding materials that state and local governments procure primarily for pavement joint sealing, concrete repair, and airfield infrastructure maintenance. Recent solicitations show heavy emphasis on hot-poured and silicone joint sealants for roadway and runway applications, deck sealers and epoxy polymer systems for concrete protection, and elastomeric compounds for bridge and taxiway joint work. The code spans functional elastomer products used in capital maintenance across transportation infrastructure, not specialty rubber compounds in isolation. Issuing bodies are predominantly state transportation departments (Maine DOT, Texas DOT, Illinois DOT), county highway and public works agencies (Collin County, Dane County, Santa Clara County, Wayne County, Barrow County), municipal transportation authorities and airport commissions (Hartsfield-Jackson Atlanta International Airport, City of Fairburn, Okaloosa County, Savannah Airport Commission), and regional transit authorities. State procurement offices manage statewide master agreements; county and city procurement offices handle localized pavement and airfield maintenance contracts.

Recent activity clusters heavily in Texas, Georgia, California, Maine, and the upper Midwest (Wisconsin, Illinois). Representative solicitations include the State of Maine Department of Administrative and Financial Services' RFQ for deck seal and epoxy polymer concrete products (RFQ17A26041300000000000259, due July 15, 2026) establishing a statewide master agreement for 400 gallons of penetrating sealers, 400 gallons of single-layer deck treatments, 5,000 gallons of double-layer treatments, and 2,000 epoxy polymer concrete kits annually; Texas Department of Transportation's IFB for Sikasil 728 RCS silicone sealant in 40 oz sausage kits for bridge applications (601340000066332, due June 26, 2026); Collin County's IFB for eleven types of liquid asphalt products (2026-277, due July 16, 2026) with estimated annual value of $100,000 and delivery within 24 hours of purchase order; and Dane County, Wisconsin's RFB for no-box hot pour sealant meeting ASTM D6690 and AASHTO M301 specifications (2026RFB036PR, due April 2, 2026), supplied per pound FOB destination. Smaller airfield and runway projects dominate the Georgia, Florida, and California activity—joint and crack sealing work at Jesup-Wayne County Airport, Hartsfield-Jackson Atlanta International, and municipal airports reflects consistent demand for elastomeric sealants in high-traffic pavement environments. The code shows no recent activity misaligned with scope; all opportunities are actively buying sealing compounds and related elastomeric products for transportation and infrastructure protection.
