UNSPSC 31201620: Reactive adhesive

A type of adhesive that works by chemical bonding with the surface material. It is usually applied in thin films.

UNSPSC 31201620 Reactive adhesive is a Commodity code that encompasses adhesive products and sealant materials used in maintenance and construction work at state and local facilities. Recent solicitations show state and local governments purchasing concrete sealants—penetrating sealers, water-based and solvent-based acrylic sealers, and epoxy or polyurethane formulations—applied to large-scale concrete surfaces at transportation facilities, maintenance bases, and infrastructure assets. The issuing bodies under this code include transit authorities, county governments, and cooperative purchasing vehicles serving multiple jurisdictions and public entities.

The Orange County Transportation Authority (OCTA) in California posted an IFB on October 7, 2026 for concrete sealant services at facilities throughout Orange County, with bids due October 14, 2026, under a one-year prevailing wage contract valued at $250,000. OCTA's scope spans twelve primary facilities and sixteen OC Streetcar passenger platforms, with five separate service line items priced per square foot: penetrating sealer (5,000 sf annually), water-based acrylic sealer (20,000 sf), solvent-based acrylic sealer (5,000 sf), epoxy or polyurethane sealer (5,000 sf), and concrete surface preparation (35,000 sf). Materials must comply with South Coast Air Quality Management District VOC requirements, and bidders must hold a valid California Contractor's License with C-8, C-61, or D-06 classification and demonstrate three years of concrete sealant experience. A second opportunity from Dallas County, Texas (reference 2100758) posted August 28, 2026 for fusion tape, 1 inch by 0.020 inch by 30 feet, with bids due October 1, 2026, though minimal detail on scope or value is available. Recent activity clusters in California and Texas; the code shows limited but concrete recent opportunity flow in state and local procurement.
