VINNAPAS® EP 907
VINNAPAS® EP 907 is a vinyl acetate/ethylene-based dispersion specifically designed for nonwoven applications that require breakdown and re-dispersion in water. When used as a binder, substrates bound with VINNAPAS® EP 907 exhibit good dry tensile strength but easily disintegrate upon exposure to water. This makes it suitable for nonwoven applications where a stiff hand and dry tensile properties are desired. When agitated in water, substrates bound with VINNAPAS® EP 907 break down into smaller fragments of individual fibers. The dispersion is stabilized with an APEO-free surfactant system and has a low formaldehyde level of less than 50 ppm.

- Application Details
VINNAPAS® EP 907 can be diluted with water prior to substrate application. Other additives can then be added under good agitation although Boron containing products may cause the product to gel. Surfactants can also be added to VINNAPAS® EP 907 to improve penetration of the binder into the substrate and improve absorbency of the finished product. Effective surfactant levels are 0.5 to 1.0% on dispersion solids.. VINNAPAS® EP 907 can be applied by a number of different application methods including saturation, spraying, foaming and print bonding. VINNAPAS® EP 907 performs well on various fiber types including cellulose, rayon, glass, and polyester based substrates. This dispersion is especially suited for use in dry wipe absorbent products. Due to the dispersion's nonionic particle charge, VINNAPAS® EP 907 exhibits good compatibility with most cationic and anionic additives.
