UNSPSC 12165000: Non shrinkage agents

Additives used to prevent cracking and shrinkage in products and to increase strength by minimizing contraction.

UNSPSC 12165000 Non shrinkage agents, a Class code, encompasses crack sealants, joint sealers, and pavement preservation products that state and local governments procure for road, bridge, and parking structure maintenance. Recent solicitations show state departments of transportation, county public works departments, and municipalities buying polyurethane and silicone-based crack sealants, hot poured joint sealers, and epoxy polymer concrete deck treatments to seal pavement cracks, bridge deck joints, and structural defects in asphaltic and Portland cement concrete. The work sits at the materials and supplies tier rather than installation labor, though state and local buyers often include sealant products as line items within broader pavement repair and rehabilitation RFPs and ITBs.

State transportation agencies (Texas Department of Transportation, Illinois Department of Transportation, State of Maine Department of Transportation), counties (Santa Clara County, Collin County), and cities (San Antonio, Salem) represent the primary issuing bodies. San Antonio's recent IFB for PolyFlex Type 3 crack sealant (due October 16, 2026) and Texas Department of Transportation's August 7 IFB for silicone joint sealant kits and caulking guns (288 kits of Sikasil 728 RCS with 72 heavy-duty guns, due August 14) exemplify the commodity-level activity—firm-fixed pricing, FOB Destination with freight prepaid, three-year terms or longer, and compliance with Texas DOT or ASTM specifications. Maine's July 2026 RFQ for deck sealants and epoxy polymer concrete (approximately 400 gallons of penetrating sealers and 2,000 epoxy polymer concrete kits annually) and State of Illinois District 5's June emergency procurement of hot poured joint sealant round out the geographic spread: Texas, California, Oregon, Maine, Illinois, and Georgia see active solicitation. Most recent opportunities impose prevailing wage, workers' compensation, and general liability insurance (typically $1 million per occurrence) as baseline requirements; few carry DBE or set-aside designations. Response cycles are tight—many close within two to four weeks of posting—and delivery windows are often constrained to business hours on weekdays.
