Viscosity and Hydrolysis
Kuraray’s PVOH grades vary in viscosity, affecting adhesion strength, film forming properties, water sensitivity, and activity as a dispersing agent.
High viscosity grades have increased film and adhesive strength, better emulsion stabilizing and dispersant characteristics, less water sensitivity and higher shear viscosity in high solids coatings. These characteristics make them excellent for adhesive applications, water soluble films, and adhesives.
