Description

Selvol 205 is a low viscosity, easy to dissolve polyvinyl alcohol generally used as a stiffener or sizing agent for textile and paper.Viscosity of a 4% solution is 5.2 up to 6.2 cps. Due to the low viscosity, this product may be applied by spray bottles. Low viscosity polyvinyl alcohol is also known as PVOH 6-88, PVOH688, Poval 5-88, PVA 205.   Repackaged for retail sale. 55-lb orders ship in original manufacturers bag, GENERAL PROPERTIES:Appearance…….
