Toxicants organotin polymers

The advantages claimed for organotin polymer-based antifouling paints include constant toxicant deHvery vs time, erosion rate and toxicant deHvery are controUable, no depleted paint residue to remove and dispose, 100% utilization of toxicant, polishing at high erosion rates, surface is self-cleaning, and function is continuously reactivated. 

Due to the non-toxic nature of the organotin polymers, they are prime candidates in the battle against cancer. They are currently undergoing further tests against various cancer cell lines. 

At the same time, there can be concerns about the disposal of organotin residues, and of traces of toxic organotin residues remaining in the products, and fluorous, polymer-bound, and solid-supported organotin compounds are being increasingly used to avoid the problem.
