POVAL™ DF-17

Technical Datasheet | Supplied by Japan Vam & Poval

POVAL™ DF-17 by Japan Vam & Poval is a denatured, easily reactive polyvinyl alcohol (PVOH) grade. It has highly reactive carbonyl groups as a denatured group other than the hydroxyl and acetate groups. Offers water-resistant films & coatings, water-based gels and functionality from post-denaturing. The carbonyl group reacts with hydrazide groups & amino groups and in particular it has an especially high reactivity with hydrazide base cross-linking agents. Is suitable for processing by flow casting. It forms coatings and membrane that do not dissolve even in boiling water. POVAL™ DF-17 can also be used to produce highly transparent gels.
