USE & PERFORMANCE
Outstanding properties: Novel line of nonionic surfactants that offers unique combinations of ben-
efits to coating, adhesives and graphic art formulations. Offer excellent substrate wetting with
defoaming, gloss improvement and pigment wetting. Anti-cratering properties, a problem solver in
water-based systems against sissing and has pronounced effect on leveling.
Recommended for polymers: a wide variety of emulsions including PUD’s, acrylics, and styrenated
acrylics
Recommended for products: Recommended for waterborne coatings intended for metal, wood and
plastic substrates. This wetting agent is effective in coatings and inks
Concentrations used, wt%: 0.25-0.75%
