Overview
Under brand name MOWITAL™, Kuraray produces polyvinyl butyral resins whose properties are characterized by presence of butyral-, hydroxyl-, and acetyl-groups. With excellent adhesive and film-forming properties, strong binding power and outstanding optical transparency, polyvinyl butyrals are utmost versatile thermoplastics. Today, main application areas are inter-layers for safety glass, paints, lacquers, and varnishes (e.g. primers for metals and anti-corrosion paints), printing inks, temporary binders, and adhesives.
