What does a buyer check before trialling a new adhesive?
Answer
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.
Information to make clear
Use the fields that affect this buying decision. Leave unsupported claims out.
- Chemistry type
- Epoxy, polyurethane, cyanoacrylate, silicone and hot-melt behave differently in every respect.
- Substrates bonded
- The first thing a buyer matches, and the reason most enquiries fail.
- Open time and cure time
- Determines whether the product fits the line speed.
- Service temperature range
- Decides survival in the application.
- Viscosity and application method
- Brush, bead, spray and film need different equipment.
- Shelf life and storage
- Drives ordering pattern and waste.
- Pack sizes
- Cartridge, pail and drum are different buyers.

Details to ask in an enquiry
Collect only the information needed to assess the request and respond.
- 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.
Related questions
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.
