Novel Modular Additive Approach for Designing Biocide-Free Coatings to Control Biofouling
Biofouling, the growth of marine organisms on man-made structures, poses numerous challenges, including >$15 billion additional fuel costs to vessel operators worldwide, cost and time for cleaning, corrosion issues, and negative environmental impacts. Anti-fouling coatings are the primary method of protection against this persistent problem, yet the widespread use of toxic, biocide-based coating products is causing even greater concerns for our environment and sustainability. Therefore, a groundbreaking coating solution is sought to protect both the environment and our properties. Adaptive Surface Technologies has been developing a modular additive approach to address this problem. The effect (physical module) has been successfully integrated with a novel library of surface active polymers (SAPs, chemical module) to form what we call active performance ingredients (APIs) that could be easily introduced as an additive in a conventional binder matrix to yield a coating formulation. This presentation will discuss the synergistic effect of customized lubricant and SAPs in controlling biofouling without using biocides, along with promising results in both laboratory and field tests. This new additive route can open up a new avenue in developing environmentally friendly, non-toxic functional additives and formulation strategies for industrial, architectural, interior and medical coatings applications.
