KURARAY POVAL™ 28-99 by Kuraray is polyvinyl alcohol. It is a fully saponified, odorless, water-soluble polymer manufactured by alcoholysis of polyvinyl acetate. It shows varying degree of polymerization and hydrolysis. Its aqueous solution can be added to polymer emulsions already stabilized with polyvinyl alcohol which affects the extension of the open time, setting speed and rheology. It exhibits good penetration capacity and good adhesion properties. It offers high cohesion, toughness, low electrostatic charging and re-dissolving capacity of the dried film in water. KURARAY POVAL™ 28-99 is designed for pressure sensitive adhesive labels. Complies with EU Directive 67/548/EC.

KURARAY POVAL™ 28-99 LA by Kuraray is a water-soluble, polyvinyl alcohol (PVOH) grade manufactured by alcoholysis of polyvinyl acetate. It exhibits high molecular weight, good cohesion and low ash (sodium acetate) content. It possesses good adhesion to fibers-, fillers- and pigments. KURARAY POVAL™ 28-99 LA is recommended for adhesive for flooring webs, PSA labels and also in remoistenable adhesives which are employed mainly in the paper processing industry and films applications.

KURARAY POVAL™ 5-82 (Old name: Poval® PVA 405) by Kuraray is polyvinyl alcohol. It exhibits specific colloid-chemical and excellent film-forming properties, and a high tensile strength. In addition, the polymers are highly elastic and resistant to heat and organic solvents. KURARAY POVAL™ 5-82 is used as a component of remoistenable adhesives, e.g. for postage stamps, partially hydrolyzed polyvinyl alcohol grades ensure that the adhesive strength is not impaired even in fluctuating air humidity. Above all, the range of applications is based on the chemical properties, especially on the reactivity of the numerous hydroxyl groups with substances such as reactive resins, aldehydes and other reactive compounds.

KURARAY POVAL™ 3-98 by Kuraray is an odorless, fully saponified polyvinyl alcohol. It is a water-soluble polymer manufactured by alcoholysis of polyvinyl acetate. It possesses good penetration capacity and good adhesion properties. It exhibits varying degree of polymerization and hydrolysis. It provides high cohesion & toughness, low electrostatic charging and re-dissolving capacity of the dried film in water. Its aqueous solution can be added to polymer emulsions already stabilized with polyvinyl alcohol which affects the extension of the open time, setting speed and rheology. KURARAY POVAL™ 3-98 is designed for use in pressure sensitive adhesive labels. Complies with EU Directive 67/548/EC.
