Specifications are based on Dongsen’s current approved product data source. Final formulation suitability should be validated under the customer’s actual formulation and process conditions.
Current commercial and technical-evaluation directions for WD-8670A include selected waterborne coating formulation areas:
These are current application-reference directions rather than product-specific confirmed application claims. For reference only. Product-specific technical validation is required.

What is WD-8670A?
WD-8670A is a water-dispersible aliphatic polyisocyanate raw material in Dongsen’s Waterbased Polyisocyanates series.
What are the current key specifications?
Current product data lists 70.0 ± 2.0% solids, 8.5 ± 0.5% NCO, free monomer ≤0.3%, and viscosity of 2000 ± 1000 mPa·s / cps at 25°C. Refer to the Technical Data tab for the specification table.
Are electronics, floor coatings and wood coatings confirmed WD-8670A applications?
They are currently application-reference and formulation-evaluation directions. They are not formal WD-8670A application mappings until product-specific technical validation is completed.
How should WD-8670A be evaluated in a customer’s formulation?
Final suitability should be validated in the customer’s actual resin system, formulation, substrate, application process and other relevant processing conditions.
