DS-201 Leveling Agent for PU, UV, and Waterborne Coatings
DS-201 is presented as a transparent liquid coating additive based on a polyether-modified silicone system, offered for PU, UV, solvent-based, and waterborne coating formulations where leveling, surface tension reduction, compatibility, and smooth finish are key sourcing checks. Buyers should verify CAS alignment, active content, solvent carrier, impurity profile, application system fit, COA/SDS availability, and export documentation before RFQ confirmation.

Package and route
Packing notes
Standard packing is listed as 200 kg iron drum or barrel; confirm net weight, palletization, drum lining, and export label format.
Request current drum photos, batch label sample, and packing list format before shipment.
Confirm whether sample packing, 1 kg MOQ trial order, and commercial drum packing use the same product specification.
Ask whether moisture control, headspace, or temperature exposure limits are stated in the SDS or COA documentation.
Confirm container loading quantity, UN marking status if applicable, and whether wooden pallets meet destination import requirements.
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
Leveling additive candidate for PU coatings
Surface tension reduction additive for coating formulations
Flow and leveling support for UV-curable systems
Compatibility-focused additive screening for waterborne coatings
Finish-smoothness additive option for industrial coatings
Trial substitute candidate where buyers are evaluating BYK-333-type performance references
How we compare
Sourcing options
Request 1 kg sample with COA and SDS for lab evaluation before drum purchase.
Source commercial packing in 200 kg iron drums after specification and DG status confirmation.
Ask for pre-shipment sample from the production batch for high-value or regulated coating applications.
Compare DS-201 against existing silicone leveling agents using buyer's own formulation and performance specification.
Request destination-specific document pack before issuing purchase order.
For recurring supply, agree on retained sample, batch traceability, COA test items, and complaint response terms.
Human review
Compliance notes
Source states COA and MSDS/SDS can be provided; buyer should request current documents for the exact batch and export destination.
CAS No. 25265-77-4 should be checked against the supplier's SDS, COA, invoice, and customs declaration because the product appears to be a formulated leveling agent rather than a single simple commodity chemical.
Verify DG classification, UN number if any, flash point, solvent content, and transport mode suitability before shipment booking.
Confirm REACH, TSCA, DSL, AICS, IECSC, Korea inventory, or other destination inventory status as applicable to the buyer's market; do not rely on marketplace text as a regulatory guarantee.
Check VOC contribution, restricted solvent content, heavy metals, silicone content, and residual monomer profile if the additive will be used in regulated coating applications.
Request allergen, SVHC, RoHS, food-contact, toy, automotive, or architectural coating declarations only if relevant to the buyer's downstream specification.
Confirm whether BCS solvent is present and whether it triggers local labeling, storage, VOC, or transport requirements in the destination market.

Questions to confirm
Can you provide the latest COA, SDS, TDS, and batch specification for DS-201?
Please confirm whether CAS 25265-77-4 represents the active component, solvent, or the full formulated product.
What is the exact active matter range, solvent content, viscosity range, density, flash point, acid value, and water content?
Which impurity items are controlled on the COA, including residual monomers, volatile solvent profile, silicone content, and heavy metals?
Is the product recommended for waterborne, solvent-based, PU, and UV systems under the same grade, or are there separate variants?
Can you provide compatibility data or customer reference use in acrylic, polyurethane, epoxy, UV-curable, or waterborne coating systems?
What is the standard export packing: 200 kg net iron drum, IBC, sample bottle, or customized packing?
Is the product classified as dangerous goods for sea, air, or road transport? Please provide DG declaration or non-DG certificate where applicable.
