SUPPLIER-FIELD MATCHING
This path normalizes quotation fields for urethane wood adhesive so factories answer the same grade, viscosity, moisture-cure or two-component, packaging and document questions. Matching is a comparison method, not an approved-vendor list or stock promise. A moisture-cure pack and a two-part structural kit are not interchangeable even when both messages mention urethane wood adhesive.
Urethane language travels across very different packs. The cards list the questions we copy onto every supplier response so alternatives stay visible. A distributor who needs a one-component moisture-cure joint fill and a mill that needs a two-component laminating system are not the same RFQ.
Ask the supplier to name one-component versus two-component, any isocyanate handling notes on the SDS, and the quoted solids or active content. A marketing toughness sentence is not identity. CAS numbers belong on the line when the buyer already holds them.
Viscosity method, open time, clamp time if claimed, color and recommended substrate moisture belong on the same row. A hardness slogan without a test method stays in the open column. Coverage numbers need substrate, film-build and whether they are theoretical or measured.
Define whether the sample is for identity, appearance, viscosity, compatibility or packaging. Acceptance stays with the buyer laboratory; this desk does not issue pass or fail. Sample mass should be stated in kilograms or cartridges, not a vague kit.
TSCA status for US supply, REACH statements where relevant, and DOT or IMDG classification are asked of the proposed concentration. They are not certificates owned by Wood Adhesive Sourcing. Related epoxy SDS files do not evidence a urethane lot.
Public product-family pages such as SpecialChem can frame the vocabulary. They do not prove that a quoted urethane wood adhesive grade matches the buyer process. Knowde and ChemPoint listings are self-reported catalogs, not our inventory and not proof of a relationship with any mill.
When a factory offers a substitute pack or chemistry, we place it on a second line with its own files. The buyer must accept that substitute pack in writing before it is priced against the original urethane line. Unit price waits until package contents, currency and Incoterm are aligned. Three limits stay explicit: we do not mix or apply urethane wood adhesive; we do not accept a related epoxy SDS as lot evidence; and we do not convert a destination that cannot receive the quoted package after the fact.
Confirm handling notes, recommended storage, shelf-life statement and transport class for the exact fill. Handling instructions are not provided on this site. Moisture-sensitive packs need a storage range from the same SDS.
Look for viscosity method, open time, substrate notes and coverage basis. Missing methods stay listed as open rather than assumed from a brochure. A clamp schedule the buyer line cannot keep is a limit, not a selling point.
Ask which assay, viscosity, color and moisture fields will appear on the shipped lot. A generic quality letter is not a CoA. Lot identity must match the quoted code.
If a supplier offers a substitute urethane wood adhesive grade, we keep both SDS revision dates visible. Laboratory, EHS, regulatory and formulation decisions remain with qualified parties using the current documents.
Send the grade, quantity, packaging and US destination. We will request factory quotes against those fields and keep unresolved documents visible.
