Mowital®

Kuraray Mowital (polyvinyl butyral) is a building block for specialty coatings and films, including TROSIFOL, polyvinyl butyral film. Kuraray produces polyvinyl butyral resins with properties that are characterized by the presence of butyral units, hydroxyl, and acetyl groups.

With its excellent adhesive and film-forming properties, strong binding power and outstanding optical transparency– polyvinyl butyrals are unquestionably versatile thermoplastic materials. Today, the main areas of application of polyvinyl butyral include inter-layers for safety glass, paints, lacquers, and varnishes (e.g. primers for metals and anti-corrosion paints), printing inks, temporary binders, and adhesives.
