POLYVINYL ALCOHOL -PVA-
A resin obtained from the saponification of polyvinyl acetate, used for the formulation of aqueous adhesive solutions to various materials, as a protective varnish for metals and a consolidant for paint films (especially in a damp state). It is soluble in water and partially in ethanol and methanol, while it is insoluble in organic solvents. Films are stable and transparent.
