About

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.
