UNSPSC 23271721: Plastic joining materials

The methods for joining plastics and composites can be divided into three major categories mechanical fastening, adhesive and solvent bonding, and welding. Welding is an effective method of permanently joining plastic components.

UNSPSC 23271721 Plastic joining materials is a Commodity code covering sealants, adhesives, and joint-filling compounds that state and local governments procure for pavement, infrastructure, and facility maintenance. Recent solicitations show the code captures hot-poured joint sealants for concrete and asphalt pavement; silicone sealants for bridge applications; and epoxy polymer concrete overlay systems. The issuing bodies span state transportation departments, counties, municipalities, airport authorities, and universities. Texas and Georgia dominate recent activity, with additional opportunities from Maine, Illinois, Wisconsin, California, and Florida. State departments of transportation (particularly TxDOT and the Illinois DOT) appear as repeat buyers, alongside county public works departments and airport authorities managing pavement preservation programs.

Representative recent solicitations include the State of Maine Department of Administrative and Financial Services requesting quotations for deck sealant systems and epoxy polymer concrete products (RFQ17A26041300000000000259, due July 15, 2026, establishing a master agreement for state-wide agencies), the Texas Department of Transportation District 5 soliciting emergency procurement of hot poured joint sealant (solicitation 26494DOTFINADB52653, due June 10, 2026), and Dane County, Wisconsin seeking no-box hot pour sealant for 2026 maintenance operations (RFB 2026RFB036PR, due April 2, 2026).
