This is what a buyer checks before they shortlist a chemicals and materials supplier.
What does a buyer check before trialling a new adhesive?
They check which substrates the product is proven on, the cure and open-time figures against their line speed, and the temperature and chemical exposure it survives in service. An adhesive that cannot be matched to a substrate pair and a process window will not be trialled, because a failed trial costs a production shift.
A process engineer is looking for a replacement bond that will not require the line to be reconfigured.

What does a buyer check before trialling a new adhesive?
What a buyer needs to identify the product
These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Chemistry type
Epoxy, polyurethane, cyanoacrylate, silicone and hot-melt behave differently in every respect.
- 2
Substrates bonded
The first thing a buyer matches, and the reason most enquiries fail.
- 3
Open time and cure time
Determines whether the product fits the line speed.
- 4
Service temperature range
Decides survival in the application.
- 5
Viscosity and application method
Brush, bead, spray and film need different equipment.
- 6
Shelf life and storage
Drives ordering pattern and waste.
- 7
Pack sizes
Cartridge, pail and drum are different buyers.
The documents buyers ask for
Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Technical Data SheetAsked at: first evaluation | Chemistry, substrates, cure profile and service limits | Publish it |
| Safety Data SheetAsked at: before a sample can enter the plant | Hazard classification, handling and transport information | Publish it |
| Lap shear and peel test dataAsked at: technical evaluation | Bond strength on named substrate pairs under a stated method | Publish it |
| Certificate of AnalysisAsked at: each delivery | Batch conformance to the published specification | Per shipment |
| Food contact or medical compliance statementAsked at: regulated applications | Suitability where the bond touches product or patient | Name it, share on request |
| ISO 9001 certificateAsked at: vendor approval | Quality system, with certificate number and issuing body | Publish it |
| Ageing and environmental test dataAsked at: before design-in | Performance after humidity, heat or chemical exposure | Name it, share on request |
Where adhesives and sealants sites lose the enquiry
Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.
Substrate pairs not named anywhere
Adhesive selection starts with the substrate pair. A product page that omits it cannot be shortlisted by anyone who knows what they are doing.
Cure and open time stated only as "fast"
A line runs at a known speed. A qualitative claim cannot be checked against it, so the engineer keeps looking.
No test method beside the strength figure
A megapascal figure without the substrate, the method and the cure condition is not comparable with a competitor's, so it is discounted.
What the enquiry form should ask
A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form — adhesives and sealants
Enough to reply usefully, short enough that a buyer finishes it.
- Substrates to be bonded
- The single most important field on the form.
- Process and line speed
- Determines whether the cure profile can work.
- Service conditions
- Temperature, humidity and chemical exposure decide the chemistry.
- Volume and pack size
- Drives price and supply format.
- Application equipment
- Existing dispensing gear constrains viscosity.
- Sample requirement
- Adhesive selection is almost always settled by trial.
Questions suppliers ask
Should we publish bond strength figures?
Yes, with the substrate pair, the test method and the cure conditions stated beside each figure. A number on its own cannot be compared with a competitor's and is treated as marketing. A number with its method is the reason an engineer picks up the phone.
How much should we say about applications we have not tested?
Say nothing, and say that you will test. Claiming a substrate you have not qualified produces a failed trial, and a failed trial with a new supplier usually ends the relationship rather than starting a conversation about conditions.
Do buyers expect samples to be free?
For evaluation quantities, usually yes, and the faster route matters more than the cost. What buyers actually judge is how quickly a sample and its data sheet arrive together, because an unlabelled sample cannot be trialled.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
