What is International antifouling?
International is one of the most recognized brands for hull protection. The range includes self-polishing, ablative and hard matrix formulations, designed to suit different operating profiles and navigation areas. Product selection depends on:
- required service life
- type of vessel
- speed profile
- cruising area
Micron range: premium self-polishing protection
The Micron series uses SPC technology (self-polishing copolymer), allowing the film to wear in a controlled manner and maintain consistent performance over time.
Micron 350
- High-grade self-polishing antifouling with up to 2 years of protection.
- Self-eroding to deliver steady performance even during lay‑ups.
- Ideal for reducing haul‑out frequency.
Micron 300
- Premium option recommended for high-fouling waters.
- Provides multi-season protection with 3–4 coats and limits paint build‑up.
