AKD Emulsion Surface Sizing Agent 20% for Paper Applications
Buyer-facing sourcing candidate for an AKD emulsion-type paper surface sizing agent, listed as a white liquid with approximately 20% sizing-agent positioning for cultural paper, packaging paper, corrugated paper, and coating-related paper applications. Key checks should focus on confirming the active content, CAS or substance identity of the AKD system, emulsion composition, pH, viscosity, solids, water compatibility, impurities, preservative content, packing format, COA/SDS readiness, and export/DG classification before RFQ or sampling.

Package and route
Packing notes
Common export packing indicated as 200 kg barrel/drum and 1000 kg drum/IBC.
Confirm whether drums are HDPE, iron drum with liner, or IBC, and whether palletization is included.
Request net weight, gross weight, pallet dimensions, container loading quantity, and shelf-life statement.
Confirm whether sample packaging differs from commercial packaging and whether sample COA is batch-specific.
Ask whether packaging is suitable for long-distance sea freight and temperature exposure during transit.
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Surface sizing for paper to improve water resistance and printability
Sizing support for cultural paper and printing paper production
Packaging and corrugated paper surface treatment where buyer trials confirm compatibility
Potential partial replacement or reduction of internal sizing agents, subject to mill testing
Use with starch-based surface sizing systems, subject to compatibility checks
How we compare
Sourcing options
Request verified AKD 20% emulsion quotation with full TDS/COA package.
Compare with styrene-acrylic surface sizing emulsions if the application is more printability/coating focused than AKD sizing focused.
Ask for trial sample and small-lot export packing before container purchase.
Source by confirmed solids content, ionic type, pH range, and mill application rather than title wording alone.
Request alternative grades for cultural paper, packaging paper, corrugated paper, or coated paper if available.
Human review
Compliance notes
Request current SDS, TDS, COA, product label, and transport classification before shipment.
Clarify exact chemical identity: AKD emulsion, styrene-acrylic ester, or blended sizing agent, as the listing text contains inconsistent naming.
Confirm CAS number or compositional disclosure for the active sizing component and key emulsion additives where available for import review.
Confirm HS code, UN number status, DG/non-DG classification, and any marine pollutant or temperature-control considerations.
Check destination-market chemical inventory status and buyer-side import requirements independently; supplier documentation should not be treated as a regulatory guarantee.
Confirm preservative/biocide content, residual monomers if styrene-acrylic components are present, VOC level, formaldehyde-related declarations if required, and heavy metal limits for paper end-use requirements.
For food-contact, packaging, or cultural paper applications, request end-use specific compliance declarations only where the supplier can support them with documents and test reports.
