ZONYLcan keep you from throwing money away on less expensive wetting agents·
Pound for pound, ZONYL/ fluoro-surfactants cost considerably more than hydrocarbon surfactants.
But, you'll use so little ZONYL to achieve superior wetting, you could wind up cutting your wetting agent costs in half. In most applications, powerful ZONYL surfactants are effective at concentrations as low as 50 to 1,000 ppm (0.005 to 0.1 %). You can even wet TEFLON*
In addition to high efficiency, ZONYL fluorosurfactants also possess high degrees of chemical and thermal stability. Therefore, ZONYL can be used in applications where hydrocarbon surfactants would decompose—in strong
acids or concentrated alkalies, or at high temperatures. And the versatile ZONYL family includes fluorosurfactants of each ionic type—cationic, anionic, nonionic, and amphoteric.
