Bayowet FT 448 Perfluoroctyl sulphonamide triethylamine Bayer-Börchers Surface conditioner, miscellaneous >> Anti-crater aid Wetting agent/ Wet edge enhancer >> Surfactant Acrylic/Acrylate Resins Polyester Coatings >> Solventborne Coatings >> Waterborne Water Bayowet® FT 448 8 Perfluoroctyl sulphonamide triethylamine Zwitter-ionic fluorinated surfactant, 10% in water Description Additive to prevent surface defects and pin holes in water-based and solvent-based paints, particularly on difficult or contaminated substrates. Solubility aliphatic hydrocarbons insoluble alcohols soluble esters soluble ketones soluble glycol ethers soluble glycol ether acetates soluble water soluble Properties The paint additive Bayowet® FT 448 acts as a flow promoter in water- and solvent-based paint systems. lt eliminates structures, orange-peel effects, craters and pin holes. lt also improves wetting of difficult and contaminated substrates. Applications The paint additive Bayowet® FT 448 possesses good binder compatibility and high efficiency in many binders. lt is particularly suited to use in chemically hardening systems, e.g. polyester isocyanate or acrylic isocyanate systems. Addition rate Recommended addition rates are 0.03 to 0.1% active substance, relative to total volume. The exact amount must be determined before large-scale use as both too large and too small amounts may give rise to adverse effects. Recoatability Loss of adhesion between base and top coat or of recoatability is unlikely when used in small amounts. Negative effects e.g. caused by overbaking may be intensified, however.
