Cyanoacrylate storage and shelf-life control start with the exact grade, package, batch label, and supplier documentation. TongLin Adhesive publishes reference shelf-life data for product grades, but the buyer should confirm the applicable label and technical documents instead of applying one storage rule to every adhesive.
Build a storage record around the product
Keep the original container closed and identify the lot, receipt date, expiry or shelf-life reference, and storage conditions used by the site. Avoid moving material into an unmarked bottle, because a new container can remove the information needed for traceability.
At receiving and before line use, check:
- grade, package size, lot number, and label match the purchase order;
- seal, nozzle, cap, and outer package are intact;
- the product has been stored according to the supplier’s current instructions;
- first-in/first-out rotation is visible to operators;
- an opened package has a defined internal use record.
The product table lists different shelf-life values by grade, including values such as 12 or 18 months and grade-specific entries. Treat those values as product references, not as permission to ignore the package label or the conditions documented for the shipment.
Match packaging to the process
| Procurement item | Why it matters | Evidence to request |
|---|---|---|
| Grade and viscosity | Affects dispensing and cure behavior | Current product data and sample approval |
| Package format | Affects protection, nozzle use, and line handling | Tube, bottle, or bulk format specification |
| Batch information | Supports incoming inspection and rotation | Label example and traceability fields |
| Shelf-life statement | Sets the usable planning window | Grade-specific document and expiry format |
S505 is a low-viscosity reference, S505 M is an enhanced low-viscosity option, and CA-S1500 is a high-viscosity gel reference. Their packaging, handling, and shelf-life details should be confirmed for the actual purchase configuration.
Align procurement and production before ordering
Send the target grade, monthly usage, package format, label language, storage route, and batch-document requirements to the supplier before approval. The correct shelf-life decision depends on the product, package, and logistics conditions; it cannot be inferred from a generic “instant adhesive” label.
For tubes, PE bottles, or larger OEM supply formats, review the cyanoacrylate OEM service. Use Contact to request current product documents, a packaging proposal, and samples for the receiving and production teams.
