I-Tech AB is a bio-tech company based in Gothenburg, Sweden that owns all IP and regulatory rights to the antifouling agent Selektope® (generic name, medetomidine). I-Tech also controls the largest and most efficient source of medetomidine production.

Since 2006, I-Tech has successfully transformed the scientific invention of Selektope® into a commercially ready and available antifouling agent.

I-Tech is not a marine coatings manufacturer - the company supplies the unique active agent  Selektope® to marine coatings manufacturers for inclusion in marine antifouling products.

I-Tech's quest to find, develop and commercialise a fouling prevention technology alternative commenced in the wake the IMO decision to ban the application of tributyltin (TBT)-based paints on vessels as of 1 January 2003. The I-Tech ‘Eureka’ moment yielded an organic, non-metal compound named Selektope. An innovation milestone for the industry that was subsequently followed by 15 years of trials, and exhaustive regulatory hurdles.


With a business concept to offer Selektope to the global paint industry as the principal active agent in marine antifouling paints, I-Tech’s vision is to become the preferred supplier to the professional and non-professional antifouling market.
