KURARAY POVAL™ R grades – PVOH with strong bonding power

Polyvinyl alcohols (PVOH) with very good adhesion are required for coating metal and glass and for demanding types of specialty paper. R grades of KURARAY POVAL™ polyvinyl alcohol have unique bonding capacity for inorganic materials. Use these PVOH polymers to enhance the performance of your coatings and specialty papers.

Strong adhesion properties for coatings on metal and glass

KURARAY POVAL™ R grades have very good adhesion to inorganic materials. That makes them ideal for coatings and as bonding agents for glass, aluminum and steel. Thanks to their built-in silanol groups, these PVOH polymers have very good crosslinking properties, resulting in excellent water resistance They are therefore ideal for water-resistant coating of specialty papers.

Demanding coatings, less bonding agent

Together with colloidal silica types, KURARAY POVAL™ R grades allow production of clear, transparent and high-gloss coatings. The excellent crosslinking properties of these polyvinyl alcohols mean that the amount of bonding agent can be reduced significantly – and that improves efficiency and reduces costs.

Give your coatings and specialty papers optimal bonding power with KURARAY POVAL™ R grades and benefit from the Kuraray PVA products that set standards worldwide.
