MOWITAL® – MEETING YOUR MOST DEMANDING NEEDS
Mowital® is the trademark for a wide range of different polyvinyl butyrals (PVB) mar-
keted by Kuraray. It has excellent adhesion and film-forming properties, high binding
power and outstanding optical transparency.
Mowital® is soluble in many organic solvents and can be combined with a wide range
of reaction partners. The major applications are highly elastic, transparent, tough
films for laminated safety glass and use as a binder in printing inks, coatings and
corrosion-protection primers.
Mowital® consists of carbon, hydrogen and oxygen and degrades thermically without
residue, producing carbon dioxide and water. Due to backward integration of the
production Kuraray uses its own polyvinyl alcohol as starting material. This allows
complete quality control of the starting polymers and thus ensures a consistently
high quality level.
Mowital® is supplied as a fine-grain, free flowing powder in paper valve bags or, on
request, in big bags. Since Kuraray constantly optimises the existing applications of
Mowital® and develops new ones. Kuraray places particular value on technical ser-
vices and close cooperation with its customers.
Polyvinyl butyral –individualist with universal characteristics
■ Enormous number of applications
■ Essential component of prepregs and composite materials
■ Improved flexibility and good adhesion to various substrates ■ Prevents steel from rusting as a component of corrosion-protection primers
■ Excellent surface adhesion
■ Superior flow and pigment wetting properties
■ Special build-up of retroreflective coatings in road traffic signs and markings

APPLICATION AREAS
The table gives an overview of the wide range of Mowital®
applications. Properties and applications depend mainly on the
degree of acetalisation and the viscosity of a Mowital® grade.
The numerical suffix of the grade designation (14, 16, 20, 30,
45, 60 and 75) indicates the increasing degree of polymerisation
(and thus the increasing viscosity). The designations T, H, S and
HH indicate different degrees of acetalisation.
