Most useful where strong
'water beading' effect is desired. FDA compliant for
21CFR 176.170 where those FDA requirements are important
in the finished article or process stream.
AQUESize 917
repellent dispersion is especially designed for aqueous
fluid repellency character. The reactive repellent
components create a strong surface repellency on the
paper/textile/nonwoven structure. Some substrates are
made so repellent water beads evaporate before any
significant surface wetting or penetration occurs.
Apparel, raingear, filtration media and surgical/medical
fabrics are end use articles benefiting from AQUESize
917 performance enhancement. Duck's back performance
is the hallmark of AQUESize 917 treatments and is
usually achieved with only 2-3% treatment.
The anionic character of AQUESize 917 dispersion
lends itself to easy incorporation in most emulsion
polymer systems. The combined latex-repellent system
allows for economical 'one-pass' processing for bonding
AND repellent application for many nonwoven or paper
substrates.
Caution needs to be taken for the presence of polyvalent
metal salts or if pH falls below 7.0.
