A small molecule with huge possibilities
Selektope® is a highly effective antifouling agent with a unique molecular structure comprising phenyl and imidazole groups. Its power lies in its ability to activate the octopamine receptor in barnacle larvae, preventing attachment at extremely low concentrations.
This biotech-driven innovation delivers exceptional protection against barnacle fouling, enhancing static guarantees and reducing the need for aggressive cleaning that can degrade coatings.
Selektope® seamlessly integrates into most coating formulations, offering a new level of antifouling performance. Its low concentration opens doors for advanced formulation concepts, including improved slime protection by minimizing the leach layer.
We call it Selektope®-power.
Power up with Selektope®
Selektope®'s unique biotechnology offers a distinctive mode of action, enabling formulation at ultra-low concentrations that outperform conventional coating systems in static performance.
With Selektope®, you can achieve extended static performance guarantees.

How can Selektope® give power to your paint system?
Less is more
High performing in small quantities.
Slow and steady release
Secures the antifouling effect over time.
Stand-alone or with copper
Used as core biocide or as booster next to Cuprous oxide.
Soluble packaging for safe handling
Makes the product easy to use in paint production.
Powerfull enough to replace, flexible enough to boost
On the market today there are formulations in which biocide loadings have been substantially reduced as the hard-fouling spectra of fouling is fully in hands of Selektope®. As this requires a different platform to start off from, the vast majority of coatings on the market use Selektope® as a booster next to existing ingredients and biocides. The way of formulating is fully up to the R&D team.
