Use the sample form and name Ventan Vef together with the intended process, substrate and any EO/PO, HLB, cloud-point or active-content window. Laboratory quantities ship after a short company check, with SDS and TDS when those boxes are ticked. A catalogue grade can be confirmed, or a custom batch planned on the Kandla plants.

Yes. SDS, TDS and COA for Ventan Vef are issued to identified companies after a short verification — they are not open downloads. COA is lot-specific; if a commercial lot has not been allocated, typical TDS data is sent first and the COA follows the production batch. Request files from the documents form.

Dyna Glycols custom-manufactures when a catalogue point in WET END - SYNTANS (Liquids) is close but not exact. Write the hydrophobe or acid/alcohol pair, the analytical window, pack and annual volume. Once a trial lot of Ventan Vef is approved, freeze the TDS so later drums match the evaluation.
