ICT provides a wide range of Thetawet Fluorosurfactants to deliver multiple benefits which can improve the performance of your coatings and formulations. Many of the Thetawet Fluorosurfactants allow for reduction or elimination of VOC in coatings formulations. Fluorosurfactants are a class of specialty surfactants developed for use in applications where traditional hydrocarbon surfactants can't deliver the required level of performance, such as:
Wetting for low energy surfaces
Fluorosurfactants are the most effective and efficient means to reduce the surface tension of aqueous coatings systems to < 20 dynes/cm and enable wetting of low energy surfaces. Hydrocarbon surfactants typically reduce the surface tension to 30-35 dynes/cm.
Smoother, more reflective surfaces can be achieved by using fluorosurfactant to improve leveling performance.
Improved penetration combined with the low energy wetting capabilities of fluorosurfactants can significantly boost the performance of cleaning products including floor and automotive polishes.
Chemical or Thermal Stability in harsh environments
Unlike traditional hydrocarbon surfactants, fluorosurfactants provide chemical and thermal stability to perform in harsh environments.
High caustic environments such as for floor strippers, harsh cleaners, rust removers
High acid environments such as metal plating baths, precision cleaning baths, metal passivation baths
Oxidizing environments such as peroxide-based cleaners, chromic acid baths
Very Low Use Levels for most cost-effective performance
Fluorosurfactants perform at very low use levels to deliver the most efficient and cost-effective solutions.
Due to the low use levels, impact on formulation stability or benefits can be minimized versus traditional hydrocarbon surfactants.
Uniformity and Reduction in Surface Defects
Uniformity of coatings can be improved with use of fluorosurfactants as well as reducing surface defects.
Better uniformity of coverage for super-thin coatings such as industrial “flash-rust” primers can be achieved.
Use of fluorosurfactants can assist with elimination of defects, such as for coatings of oil-contaminated surfaces.
ICT Thetawet fluorosurfactants are available with a range of low foam to high foam characteristics.
Improvements in open-time and anti-blocking
For paints and coatings, open-time extension and block resistance are additional benefits for use of fluorosurfactants.
