UNSPSC 31201703: Silicone encapsulation

Potting of electronic components using silicone based materials

UNSPSC 31201703 Silicone encapsulation, a Commodity code, covers specialized sealant and encapsulation products used in maintenance, repair, and construction applications across state and local facilities. Recent solicitations show state and local governments procuring silicone-based sealers and encapsulants for paint preparation, joint sealing, stain treatment, and equipment maintenance—work that spans general building maintenance, residential housing renovation, and fleet vehicle service. The issuing bodies include county governments (Seminole County, Dallas County), state-level cooperative purchasing entities (Sourcewell on behalf of Minnesota and multiple Washington counties), regional transit authorities (Dallas Area Rapid Transit Authority), and public universities (University of Texas at Tyler). The work involves both routine maintenance contracts with standing term agreements and project-specific solicitations tied to facility upgrades or capital improvements.

Recent activity concentrates in Florida, Texas, and the Upper Midwest / Pacific Northwest region, with representation also from cooperative purchasing vehicles that serve nationwide jurisdictions. Representative opportunities include Seminole County's term contract for caulking, coatings, joint sealant, and pressure washing services (IFB 604483-22/LNF, due February 1, 2023); the University of Texas at Tyler's Liberty Landing Apartments residential paint and interior repairs project (RFP RFPNO7502526007, due April 3, 2026, with mandatory pre-bid conference March 18, 2026), which explicitly calls for stain encapsulation and zero-VOC Sherwin-Williams paint application; Sourcewell's law enforcement equipment cooperative procurement (RFP #061626, due June 16, 2026), which may include sealant components within broader equipment scope; and Dallas Area Rapid Transit Authority's straightforward goods procurement for RTV Cummins Sealer (posted March 11, 2026, due March 13, 2026). The code shows relevant activity in specialized maintenance and capital-project contexts, with response windows ranging from two days to over one month depending on procurement complexity and notice type.
