Kuraray’s PVB binder resin, MOWITAL™, is used in semiconductor and electronic applications where process stability, yield improvement, and quality reproducibility are required.

With low impurity levels and low undissolved content, MOWITAL™ helps suppress defect generation and supports stable manufacturing processes. It also offers excellent dispersion performance, enabling uniform distribution of inorganic materials.

MOWITAL™ is used as a binder for MLCC, conductive pastes, and electronic components for semiconductor equipment.

Leveraging Kuraray’s fully integrated manufacturing from raw materials, we are exploring new applications together, starting from process challenges.
