UNSPSC 31201632: Silicone adhesive

A liquid adhesive containing silicone used in a variety of applications

UNSPSC 31201632 Silicone adhesive is a Commodity code, but the recent state and local opportunities posted under it show a significant mismatch between the code's nominal scope and actual buying activity. The Orange County Transportation Authority (OCTA) solicited concrete sealant services—a surface protection application involving penetrating sealers, water-based acrylic sealers, solvent-based acrylic sealers, and epoxy or polyurethane sealers—rather than silicone adhesive products. Dallas County, Texas posted a request for fusion tape (1 inch by 0.020 inch by 30 feet), which is a fastening or sealing material but not a silicone adhesive. A third posting from Sourcewell, a Minnesota cooperative purchasing vehicle, sought law enforcement equipment on behalf of multiple state and local jurisdictions across Washington and nationally, which bears no relationship to adhesives or sealants. The code shows little relevant recent activity aligned with its stated commodity category.

The OCTA concrete sealant services IFB (250318, due October 14, 2026) remains the closest representative opportunity, requiring a California-licensed contractor to perform surface preparation and application of multiple sealant types across twelve facilities and sixteen OC Streetcar platforms in Orange County, with an estimated contract value of $250,000 for a one-year term and firm-fixed pricing per square foot. The contract is subject to prevailing wage and DBE participation requirements. Beyond OCTA in Orange County, California, and the unrelated Dallas County and Sourcewell postings, the source does not support characterizing a broader geographic or issuing-body pattern for silicone adhesive procurement at the state and local level.
