UNSPSC 31201711: Parylene conformal coating

A chemical vapor deposited polymer used to coat electronic component circuitry for protection against environmental or physical damage

UNSPSC 31201711 Parylene conformal coating is a Commodity code that captures specialized protective coatings and sealants applied to equipment and building surfaces in state and local procurement. Recent opportunities tagged to this code show a mix of actual application: interior painting with surface preparation and drywall repair at university housing (University of Texas at Tyler), term contracts for caulking, joint sealants, and pressure washing services on county properties (Seminole County), industrial sealer procurement for transit authority equipment (Dallas Area Rapid Transit Authority), and broad cooperative law-enforcement equipment solicitations that may include protective coatings as ancillary components (Sourcewell on behalf of Washington counties and other jurisdictions). The code reflects both standalone coating and sealant services and integrated facility-maintenance contracts where coatings are one element of a broader scope. Issuing bodies span state universities, county governments, transit authorities, and regional cooperative purchasing vehicles serving multiple jurisdictions.

Activity appears concentrated in the South and Pacific Northwest. University of Texas at Tyler (Tyler, Texas) issued an RFP for interior painting and drywall repair at Liberty Landing Apartments due April 3, 2026, structured as a lump-sum fixed-price contract with 70 percent evaluation weight on contractor qualifications and prevailing wage compliance required.

Dallas Area Rapid Transit Authority (Dallas, Texas) solicited RTV Cummins Sealer on March 11, 2026, with a two-day response window (due March 13, 2026) for a specific industrial sealer product.
