Self Polishing Antifoulings
By carefully combining pure SPC technology with rosin-based CDP technology, it has been possible to produce technology which combines the CDP features of surface tolerance and attractive volume solids, together with the SPC benefits of polishing rate control, control of biocide release and reduced leached layer size.
The addition of a hydrolysable polymer to rosin to form self polishing antifoulings has been patented by International and performance has been enhanced by the use of a co-biocide.
In terms of performance this SPC/CDP antifouling is midway between the SPC and CDP technologies.
