UNSPSC 31201703: Silicone encapsulation

Potting of electronic components using silicone based materials

UNSPSC 31201703 Silicone encapsulation, a Commodity code, covers protective coating and sealing materials applied to concrete and other surfaces in state and local infrastructure maintenance. Recent opportunities show state and local governments buying concrete sealants — including penetrating, water-based acrylic, solvent-based acrylic, and epoxy or polyurethane formulations — along with surface preparation services such as cleaning, crack filling, and patching. A single high-value representative solicitation from the Orange County Transportation Authority (OCTA) illustrates the market: the IFB for concrete sealant services at transit facilities, posted October 7, 2026, with bids due October 14, 2026, specifies five separate service line items across thirty-five thousand to five thousand square feet annually of various sealant types and surface prep work, under a one-year contract valued at $250,000 with mandatory prevailing wage and DBE participation requirements. Issuing bodies soliciting under this code include transit authorities and county governments; OCTA appears as a significant buyer in the recent activity.

Activity under the code is concentrated in California, with the Orange County Transportation Authority representing the primary recent opportunity in the dataset. The Dallas County, Texas solicitation for fusion tape (posted August 28, 2026, due October 1, 2026) and a Sourcewell cooperative purchasing RFP for law enforcement equipment (posted May 12, 2026, due June 16, 2026) appear to be tagged to this code but diverge substantially from its nominal scope — fusion tape and law enforcement gear fall outside typical silicone encapsulation procurement. The code shows limited recent activity aligned with its stated commodity definition; decision-relevant procurement under 31201703 is narrow and driven by transit and facility maintenance needs in specific jurisdictions.
