Grades with SDS-first manners
AssayPack, founded 2008 in Nanjing Chemical Park, operates a 15,000 m² facility with 130 staff and 8 reactor lines. Annual capacity: 28,000 tonnes across epoxy, PU, and acrylic resin families—serving 200+ formulators in 35 countries.
Certified to ISO 9001, ISO 14001, and REACH-registered, we treat the document pack as part of the product: English SDS and CoA ship by default with revision stamps. Sampling is sized for lab trials—not warehouse overship. Tell us the application resin and annual tonnage; we prioritize kits with handling notes, not dumped drums.

What buyers dig into first
- 01
SDS / CoA desk
English packs by default, with REACH summaries queued within two hours for named grades when destination market is clear.
- 02
Dosage windows
Published loading ranges for common resin systems—three resins deep on the site, deeper tables on request.
- 03
Sample kits
Lab-trial grams with handling notes and typical pot-life expectations so RFQs stay realistic.
- 04
Batch tone
Lot and method IDs follow CoA fields overseas QA already scans—revision stamps live near the download, not buried in a PDF footer.
