Ester-Soluble Polyamide Resin PA DR-911E for Gravure and Flexographic Ink Sourcing
Ester-soluble polyamide resin candidate for solvent-based gravure and flexographic plastic printing inks, paper inks, overprint varnish, and seal coating applications. Key buyer checks should confirm exact resin identity or CAS/registration status where applicable, ester solubility, acid and amine value limits, viscosity test method, Gardner color, melting point range, packing format, COA/TDS/SDS availability, and export/DG classification before RFQ or sample approval.

Package and route
Packing notes
Standard packing stated as PE film-lined PP woven bag, net weight 25 kg per bag
Confirm palletization, moisture protection, bag labeling, batch number format, and export marks
Ask whether sample quantities are available and whether sample COA matches commercial lot testing
Confirm shelf-life, recommended storage statement on SDS/TDS, and whether anti-caking or moisture limits are specified
Request photos of original bags, pallet packing, and container loading method for export orders
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
Binder or adhesion resin candidate for solvent-based gravure plastic printing ink
Resin component for flexographic plastic printing ink where ester solubility is required
Polyamide resin candidate for paper printing ink formulations
Resin component for overprint varnish applications
Seal coating resin candidate subject to buyer formulation testing and compliance review
How we compare
Sourcing options
Request DR-911E as the quoted grade and compare against buyer's current ester-soluble polyamide resin specification
Ask for a pre-shipment retained sample and COA for every production lot
Source trial sample first, then scale to 1,000 kg MOQ or full container quantity after lab and print-performance validation
Consider alternative ester-soluble PA grades if viscosity, color, melting point, or amine value must be tighter
Use third-party inspection or lab testing for first commercial shipment, especially for regulated packaging ink supply chains
Human review
Compliance notes
CAS number is not provided in the source data; request exact chemical identity, polymer description, and CAS/EC/TSCA/REACH inventory status where applicable
Request current SDS, TDS, COA, allergen/food-contact statements only if relevant to buyer's end use, and composition disclosure appropriate for customs and regulatory screening
Confirm whether the product is classified as dangerous goods for sea, air, rail, or road transport; do not rely on marketplace descriptions for DG status
Verify HS code, country of origin, export license requirements, and import restrictions for the destination country before purchase
Confirm residual monomers, solvent residues, heavy metals, VOC-related declarations, and restricted substance statements if used in packaging inks or regulated printing applications
No regulatory guarantee should be assumed from ISO, audited supplier, or marketplace badges; buyer should perform independent compliance review

Questions to confirm
What is the exact CAS number or polymer identity for this ester-soluble polyamide resin, and is DR-911E a fixed grade or customizable grade?
Can you provide recent TDS, SDS, COA, and a sample COA from the same production line?
What are the exact viscosity test conditions, including solvent, resin concentration, spindle or cup method, temperature, and standard used?
What impurity or quality-control parameters are available beyond acid value, amine value, color, viscosity, and melting point?
Are residual solvent, residual monomer, moisture, ash, heavy metals, odor, gel content, or insoluble matter tested?
Which ester solvents have been validated for solubility and what clarity or filtration standard is used?
Is the grade intended for gravure plastic ink, flexographic ink, paper ink, overprint varnish, or seal coating, and which application has the most stable commercial history?
What is the minimum order quantity, sample quantity, lead time, and monthly export capacity for the requested specification?
