KURARAY MOWITAL™

SEPPIC distributes the MOWITAL™ range of KURARAY in France. 

The material for thousand applications

Under the brand name MOWITAL^TM, Kuraray produces polyvinyl butyral resins (PVB) whose properties are characterized by the presence of butyral-, hydroxyl-, and acetyl-groups.

With excellent adhesive and film-forming properties, strong binding power and outstanding optical transparency, polyvinyl butyral are utmost versatile thermoplastics, used today in many applications: inter-layers for safety glass, paints, lacquers and varnishes (e.g. primers for metals and anti-corrosion paints), printings inks, temporary binders and adhesives.

• Compatible with many polymers, MOWITAL^TM enables ideal crosslinking of various functional groupe of organic substances.
• The PVB is ideal for use with a wide range of solvents - from non-polar solvents like hydrocarbons to highly polar solvents like methanol.
• MOWITAL^TM is available in variants with different viscosities, from low to high viscous grades.

Nomenclature of MOWITAL^TM

MOWITAL^TM B 20 H

• The alphabetical prefix B, BA and SB points to the type of functionalization of the polymeric backbone, B for acetalization with butyraldehyde, BA for co-acetalization with butyraldehyde and acetaldehyde, and SB for acetalyzation with butyraldehyde with additional specification. These 3 families of grades are available as powders. A selection of grades are also available in granular form under the name MOWITAL^TM G (please consult us).
• The numbers 14, 16, 20, 30, 45, 55, 60, 70 and 75 contained in the type designation for MOWITAL^TM are relative measures indicating the increasing degree of polymerization or molar mass and thus the rising solution viscosity.
• The alphabetical suffix T, H, S, HH points to the increasing degree of acetalization, which indicates on one side a decreasing polarity of the polymer, Tg and tensile strength, and on the other side an increasing water resistance, solubility in non-polar solvents, compatibility with non polar polymers and elongation properties.
