Selvol™ Polyvinyl Alcohols offer unparalleled results as additives or modifiers in polyvinyl acetate emulsion-based adhesives as well as in solid fiber laminating and spiral tube winding adhesives.
Selvol™ Polyvinyl Alcohol resins have been used for more than 40 years as modifiers for polyvinyl acetate emulsion adhesives because of their many outstanding characteristics.
Polyvinyl alcohol adheres particularly well to cellulosic substrates such as paper and wood. Adding it to a polyvinyl acetate emulsion will increase the efficiency as well as the tensile strength of the resulting adhesive.
Before choosing any of the Selvol™ Polyvinyl Alcohol grades, please consider the material you will be working with and whether you will be using it as a sole adhesive or a compounding adhesive.
PVOH molecular weight and hydrolysis levels have a large influence on the final properties of the adhesive. In general, higher molecular weight PVOH grades will result in emulsion polymers with higher viscosity, increased shear thinning, higher tensile strength and higher wet tack. Lower hydrolysis levels will create good stability, increased water sensitivity and improved freeze – thaw stability.
