Equipment developments deserve a close look through the lens of small craft, with installation, compatibility and service support checked before buying. International is expanding Micron 350 into Asia-Pacific, bringing its self-polishing multi-season antifouling to owners and yards operating in warm, high-fouling waters.
The original industry announcement documents the release, while this report considers its relevance to the under-twelve-metre boating market without assuming every model or installation is eligible.
International is expanding Micron 350 antifouling into the Asia-Pacific market, targeting owners and professional applicators working in warm waters with heavy marine growth. The self-polishing coating is designed for multi-season protection and can provide up to two years of service when applied to the specified film thickness.
AkzoNobel says the regional rollout responds to demand for a proven product able to cope with tropical and subtropical fouling conditions. Micron 350 has already been used in Europe across cruising yachts, including boats that remain stationary for extended periods.
Self-polishing technology controls paint build-up
Micron 350 uses self-polishing copolymer technology, gradually renewing the exposed coating surface as the yacht moves through the water. That process helps control excessive accumulation of old antifouling layers while maintaining active protection.
A smoother underwater surface can also reduce unnecessary drag compared with heavily built-up coatings. The effect on fuel use will vary by yacht and operating profile, but clean underwater surfaces remain an important part of hull efficiency.
Up to two years between applications
International specifies different coating schemes depending on whether the target service period is one or two years. Brush and roller applications require additional coats for the longer interval, while professional airless spraying uses a different recommended dry-film thickness.
Owners should not assume that the maximum interval applies automatically in every marina. Fouling pressure, water temperature, usage and maintenance can all affect real-world performance, particularly in tropical locations.
The coating works while yachts remain stationary
AkzoNobel highlights protection during stationary periods as an important part of the Asia-Pacific launch. That is relevant to privately owned yachts that may spend weeks or months in warm marinas between cruising periods.
Micron 350 is suitable for GRP, wood, steel, cast iron and lead when the correct preparation and primers are used. It is not intended for aluminium or alloy substrates, so owners need to match the product to the hull and underwater fittings.
Antifouling choice affects ownership costs
Underwater coatings influence haul-out frequency, cleaning requirements and the amount of preparation required at the next yard period. A multi-season system can reduce maintenance disruption if it performs consistently in the yacht's actual cruising environment.
For LYG owners cruising Asia-Pacific, the expansion provides another established antifouling option designed specifically around high-growth waters. The practical decision remains a combination of hull material, cruising speed, local fouling conditions and yard application quality.
Fitment to boats below twelve metres must be checked with the manufacturer or authorised installer. Product dimensions, electrical loads, certifications and installation requirements cannot be assumed from a show presentation.
The official product photograph identifies the release, but the actual installed configuration may differ. Owners should use the published specification and professional advice before ordering.
