Plan a trial for your application
Glass or mineral surface coupling
Use the same substrate and pretreatment. Compare dry adhesion and adhesion retention after humid heat aging.
Filler-modified composites
With the same filler and cure formulation, compare dispersion, strength and interfacial performance after water uptake.
Purchase specifications and incoming inspection
Include the intended grade or current specification in the enquiry. Use the table to compare selection criteria and inspection conditions. The specification agreed by both parties defines the contractual limits. Evonik · Dynasylan AMEO technical data and test conditions ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Density at 20 °C | g/cm³ | Evonik Dynasylan AMEO third-party typical value, approximately 0.95 | The cited sheet specifies DIN 51757. Confirm the purity of the proposed silane separately when ordering. |
| Principal silane content | % by mass | Use the COA for the offered grade. | Check the chromatographic reporting basis and list water and hydrolysis products separately. |
| Wet adhesion retention | % | Agree on the actual substrate. | Fix curing and water-immersion conditions and compare wet and dry results. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
Chemical identity
| Database entry | Molecular or composition formula | Molar mass |
|---|---|---|
| (3-Aminopropyl)triethoxysilane | C9H23NO3Si | 221.37 g/mol |
The values refer to the compound indicated. Confirm hydrate form, solution concentration and blend composition for the commercial grade.
From samples to commercial delivery
Packaging and receiving
Select sealed drums or smaller packs according to use per opening. Check closure and container dryness.
Storage and handling
Record lot and exposure time after opening. A repeatedly sampled container is not equivalent to a factory retention sample.
Sample and order lead times
State the finished part, machine trial quantity and routine order size. Match trial and commercial grades and agree MOQ, load unit, lead-time start and arrival.
Questions from the plant
Why does adhesion vary after apparently identical surface treatment?
Fix pretreatment and cure. Compare dry and wet adhesion before and after treatment.
Why did an opened drum perform differently on its second use?
Check sealing, sampling humidity and substrate moisture. Retest against an unopened sample from the same lot.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check chemical identity and purity, Moisture, substrate surface condition.
