Does the SDS match the quoted concentration?
Ask for the current safety data sheet tied to the cartridge or bulk SKU, not a family file for another viscosity.
Application-to-purchase questions
Structural adhesive aluminum briefs that stay on the RFQ
Translate assembly context into purchase fields for structural adhesive aluminum: alloy if known, surface condition, gap, quantity and destination. This page does not certify a joint design or promise a lap-shear result.
- 01 Alloy and surface notes written as questions
- 02 Gap, pack and destination kept on one sheet
- 03 SDS, TDS and CoA left open until the SKU is quoted
Application matrix used only to write purchase fields
Rows are buyer contexts. Columns are specification questions copied into the RFQ. Public product-family pages, including this chemical-family reference, help name viscosity or chemistry families; they do not confirm inventory or supplier capability.
| Buyer context | Identity to record | Measurable fields | Documents still open |
|---|---|---|---|
| Sheet or extrusion joints | Chemistry family and whether a primer is requested | Viscosity, open time, gap-fill note | SDS, TDS, CoA format for the quoted SKU |
| Honeycomb or panel edges | Grade intended for edge fill versus thin-film bonds | Density, solids content, package size | Transport class matching that concentration |
| Dissimilar-metal assemblies | Named substrates and any isolation requirement | CTE-related questions stay as questions, not claims | Exact-product SDS before any shop trial |
| Distributor restock | Cartridge ratio or bulk pack the downstream customer expects | Quantity unit, pallet notes, US destination | Lot-controlled CoA versus typical sheet |
Material and method trade-offs buyers still decide
Acrylic or MMA grades can shorten fixture time on some aluminum assemblies and can also raise odor, ventilation and primer questions that epoxy grades do not share. Epoxy grades can offer longer pot life and can also need heat or longer fixture time. Neither path is declared better here. A second trade-off sits between high-viscosity gap fill and thin-film wetting: the receiving process must name the gap, not this website. A third trade-off sits between room-temperature cure and heat-assisted cure; energy, fixture count and SDS flash-point language all change, so the quotation must restate the intended path.
Limitation: aluminum oxide and residual drawing oil change wet-out even when two quotes share a chemistry name. Surface-prep methods belong to the buyer and any named process owner. Another limitation: a TDS lap-shear figure measured on degreased 2024 coupons is not evidence for mill-finish 6061 in a wet environment. A third limitation: moisture and trace metals on a CoA, when requested, apply only to the shipped lot and do not replace incoming inspection at the receiving site.
If chloride, primer or anodize notes matter, write them as open fields. Do not treat a catalog photo of an aluminum assembly as proof that the quoted product was already validated on that alloy. Return open items through the RFQ page or the quote workflow.
Document questions that follow aluminum-facing briefs
What TDS limits are lot-controlled?
Request which viscosity, mix ratio and pot-life numbers will appear on the CoA versus typical marketing ranges.
Which transport class is proposed?
UN number and packing group must follow the exact SDS, carrier rules and destination law. This desk does not classify freight.
What remains unresolved after the first answer?
Keep sample mass, primer questions and alloy notes visible instead of filling them with assumptions.
Turn the aluminum context into a brief
Record alloy if known, surface-prep questions, intended gap, quantity and the US plant city. Application photos stay as questions; they are not converted into lap-shear claims.
