I-Tech AB, developers of antifouling biotechnology, and global specialty chemical company LANXESS have combined their respective antifouling technologies for the first time, reports Offshore Energy.
About the trials
The duo carried out static tests of antifouling coating formulations containing Selektope and the SEA NINE™ family of biocides in multiple marine environments worldwide with differing biofouling risks. The companies said that they” have positive results providing proof of concept.”
They have also developed a data pool of coating formulations that can be used by antifouling coating manufacturers to support the trialling of new combinations of existing, available biocides without the need to conduct initial R&D exploration activities.
Antifouling coatings are the first line of defence against biofouling accumulation on ship hulls and niche areas. It is extremely important in keeping vessel efficiency as fouling leads to increased fuel consumption and emissions in additionto the spread of invasive species.
Continuously protecting the underwater surface of a vessel that can have changeable operating patterns and transits in and out of varying biofouling risk zones for up to five years is very tricky.
Coating systems that make use of biocides are the most common type utilised today. However, the number of approved biocides available to paint manufacturers has significantly decreased during the past decade. Therefore, finding new ways to combine existing biocides is essential.
Collaborative R&D efforts between biocide suppliers play a key role in supporting the optimisation of future antifouling coating technologies by providing proof of concept and initial R&D findings. This can enable coating manufacturers to fast-track product development and improve antifouling performance.
“This year the I-Tech R&D team is harvesting the results from many successful collaborative projects undertaken with fellow antifouling technology developers. We believe this is the only way forward when trying to ensure that our technology helps the maritime industry to tackle increasing biofouling issues,” Dr Markus Hoffmann, Technical Director at I-Tech commented.
“Biocidal antifouling coatings are here to stay and at I-Tech we are invested in ensuring that the technology available now can be used to best effect in the future by proving performance across as many different potential application scenarios as possible.”
