KURARAY POVAL™ R – the PVA with built-in silanol groups
KURARAY POVAL™ R grades are polyvinyl alcohols with built-in silanol groups. Their exceptional bonding power ensures extremely good adhesion to inorganic materials such as glass, aluminium and steel. The silanol groups in KURARAY POVAL™ R polymers mean they can also be crosslinked, which improves the water resistance of the resulting coatings. In combination with colloidal silica types, clear, transparent and high-gloss coatings can be produced.
