Product selection should begin with your resin type, application, formulation system, curing conditions and target properties. Share these details with Dongsen so the team can identify a suitable product direction for evaluation. Final compatibility and performance should be confirmed through formulation testing and the applicable TDS. You can send your requirements to Dongsen for selection support.
Please provide your resin or binder type, solvent-borne or waterborne system, application or end use, curing conditions, target properties and any current formulation issue. Your country and company details also help Dongsen review the appropriate supply and documentation path. Submit the available information through the technical inquiry form.
Dongsen raw-material directions are used by formulators working on selected coating and adhesive systems, including wood and furniture, automotive and industrial, floor, can and coil, electronics, flexible-packaging adhesive and footwear-related applications. Suitability depends on the complete formulation, process and required performance. Review the application overview before requesting a grade recommendation.
Samples may be arranged for formulation evaluation, subject to product availability and application review. Provide your resin system, target application, destination country and test objective so Dongsen can review the request. Use the contact form to request a sample.
Available technical and safety documents can be provided according to the selected grade and its current document status. A COA may be supplied for an applicable commercial batch. Contact Dongsen to confirm which documents are available for your required grade and market through the document request form.
If you know the grade, provide the product name, estimated quantity, destination country and application. If the grade has not been selected, send your resin system, process conditions and target requirements first so the product direction can be reviewed before quotation. Start your request on the Dongsen Contact page.
Product availability, logistics and documentation requirements should be confirmed for the destination country and the specific grade. Tell Dongsen your market, application and required documents before ordering. A shipping route or previous supply does not by itself confirm regulatory registration or compliance. Please contact Dongsen for a market-specific review.
Use the Dongsen Contact page and select the type of support you need. Include your name, company, email, country, application and requirement details so the team can route the inquiry efficiently.
