NIGP 31590: Resins (Epoxy Only)

NIGP 31590 Resins (Epoxy Only), an Item code, covers high-performance epoxy flooring systems that state and local governments install in industrial and specialized facilities—primarily aircraft hangars, maintenance shops, and wastewater infrastructure environments where chemical resistance, load-bearing capacity, and durability are critical. The work involves mechanical surface preparation, multi-layer epoxy primer and body coats, aggregate broadcast for slip resistance, and protective topcoats, often with extended warranty requirements and stringent performance standards. Issuing bodies include county capital projects departments and municipal water and wastewater utilities, which solicit these services through RFPs and competitive sealed-bid proposals.

Recent activity shows Beaufort County, South Carolina issuing an RFP (Solicitation 070326) for approximately 7,500 square feet of aircraft hangar floor resurfacing at Lady's Island Executive Airport, with proposals due July 8, 2026, requiring mechanical surface preparation to CSP 3-5 standard, 100% solids epoxy flooring with slip-resistant aggregate broadcast, and urethane topcoat—with base and optional alternates for extended warranty coverage. Dallas County is simultaneously procuring trenchless wastewater pipeline rehabilitation (Solicitation CIZDWU26040, due June 5, 2026), which incorporates epoxy-based or resin-lined pipe methods (Machine Spiral Wound Liner and Cured-In-Place Pipe followed by high-density polyethylene slip lining) for approximately 5,150 linear feet of 1950s-era reinforced concrete pipe, with SBE set-asides and local participation requirements. Both solicitations demonstrate demand for epoxy and resinous systems in specialized, high-durability applications subject to chemical exposure, heavy loads, and regulatory environmental constraints.
