GENERAL INFORMATION:
PolyFox PF-636, PF-6320, PF-656, and PF-6520 fluorosurfactants are environmentally preferred , 100% solid, solvent-soluble diols
based on OMNOVA Solutions’ platform of poly(oxetane) polymers. When formulated properly, PolyFox fluorosurfactants may be used toreplace telomer- based fluorosurfactants.
KEY FEATURES AND BENEFITS:
Environmentally Preferred – Compared to certain telomer-based and other conventional fluorosurfactants, PolyFox
fluorosurfactants have been found to not bioaccumulate, resulting in very low environmental impact .
Formulation Versatility – PolyFox fluorosurfactants offer formulators improved flow, leveling, and surface appearance without the
typical air entrainment problems associated with conventional fluorosurfactant. PolyFox fluorosurfactants’ perform both as a deaerator and as a flow and leveling agent reducing the need for multiple additives.
Improved Flow and Leveling – Incorporation of PolyFox fluorosurfactants into coating formulations results in improved coating
appearance by reducing surface waviness and orange peel (see Figure 1).
Outstanding Air Release and De-Aeration – Incorporation of PolyFox fluorosurfactants results in dramatically reduced airentrainment, minimizing surface defects such as pinholes and craters (see Figure 2).
Near Water White Color –PolyFox fluorosurfactants are clear and uniform in appearance making them particularly well suited
for use in clear formulations.
Excellent Solubility – PolyFox fluorosurfactants are completely miscible in essentially all commonly used coatings solvents.
Theseproducts are readably miscible with polymers such as alkyds, polyesters, cellulosics, acrylics, and 100% solid coatings systems.
100% Active – PF-636, PF-656, PF-6320 and PF-6520 are 100% (by weight) active and do not contain VOCs.
