Styrene Butadiene Rubber Latex (SBR Latex) Binder for Paper Coating Applications
Buyer-facing sourcing candidate for SBR latex binder used in paper coating, sizing, adhesive paper, composite paper, and functional coating systems. Key checks should focus on CAS alignment, 50% solid content confirmation, viscosity range by paper grade, Tg range, pH, particle size, packing format, COA/TDS/SDS availability, and export documentation readiness.

Delivery time listed: 7 working days after payment; confirm for current stock, production batch, and export booking schedule
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 for coated paper surface smoothness and printability improvement
Sizing binder for high-speed paper production lines
Adhesive paper and tape base cloth binder applications
Composite paper bonding with film, foil, or functional layers
Anti-sticking or anti-slip paper coating formulation component
Functional paper binder for greaseproof, flame-retardant, decorative, or specialty paper systems, subject to formulation and compliance validation
How we compare
Sourcing options
Request standard 50% solid content SBR latex grade for paper coating trials
Request viscosity-adjusted grade based on paper machine speed and coating formulation
Request Tg-specific grade within listed 0 C to +27 C range for target film properties
Request IBC packing for bulk production orders or smaller drums for pilot runs
Request FOB Qingdao, CFR, CIF, or FCA quotes depending on buyer freight control preference
Request batch-specific compliance package before sample approval and before bulk shipment
Human review
Compliance notes
Request latest COA, TDS, SDS, product label, packing list template, and certificate of origin before purchase confirmation
Confirm dangerous goods classification, UN number status if any, transport restrictions, and whether the latex is shipped as non-DG under the supplier SDS
Check residual monomer limits, volatile content, preservative/biocide system, APEO status, formaldehyde-related declaration if relevant, and heavy metal declarations for paper or packaging applications
Confirm import requirements for the buyer destination, including polymer registration status, customs HS code acceptance, and any food-contact or packaging-contact restrictions if the paper application requires them
Do not rely on marketplace claims as regulatory approval; require batch-specific and destination-specific documentation review
If use is for food packaging, liquid packaging paper, flame-retardant paper, or other regulated paper grades, request application-specific compliance declarations from the supplier and independent verification where needed
