Specifications are based on Dongsen’s current approved product data source.
DL-75 can be used to formulate 2K polyurethane wood and furniture coatings for indoor applications.
Dongsen supplies DL-75 as a polyisocyanate hardener / crosslinker raw material, not as a finished paint or coating.
Use the Technical Data tab for solids content, NCO content, free TDI, viscosity and solubility / tolerance values. These specifications are intentionally not repeated here.
If your application requires comparison between different Dongsen grades, ask Dongsen to review the application requirements and suggest a suitable grade direction.
