USE & PERFORMANCE
Outstanding properties: Excellent surface tension reduction agent. Provide rapid substrate, pig-
ment wetting and perform in a wide range of applications. Provide performance comparable to
alkyl phenol-based surfactants in waterborne coatings, inks, and adhesives systems. Can improve
the freeze-thaw stability of acrylic systems, excellent oil-in-water emulsifier, cost-effective. Con-
tain no added alkylphenol ethoxylates, contain no added solvents or hazardous air pollutants. Offer
outstanding wetting and deaeration of organic and inorganic pigments, little to no impact on sys-
tem rheology, water resistance, dry-time, block resistance, gloss, or opacity. Improved color rub-up
and color acceptance for an enhanced touch-up. Contain no added APEs or solvents. Provide a
superior balance of properties compared to traditional fluorosurfactants and silicone surfactants.
Offer outstanding dynamic wetting, excellent flow and leveling, and low foam
Recommended for products: architectural coatings, industrial coatings, inks, adhesives, metal coat-
ings, wood coatings, printing inks, flexographic and gravure inks, floor polishes, leather coatings,
metal/plastic primer and topcoats
