Product details

INTERNATIONAL MICRON 350 - Self-polishing high-performance antifouling

MICRON 350 from INTERNATIONAL is a highly developed antifouling product that has been specially designed for use in maritime watersports. It provides effective protection for boats and yachts in salt water, fresh water or brackish water. Because it is self-polishing, it ensures a smooth surface and reduces the growth of algae and other organisms.

Self-polishing technology for optimum protection

The self-polishing copolymer technology used in Micron 350 antifouling ensures continuous renewal of the protective layer. This leads to an even biocide release and prevents the formation of thick layers, which improves the boat's performance and reduces fuel consumption, making it particularly suitable for boats that spend long periods in the water.

Versatile application options for Micron 350 antifouling

INTERNATIONAL Micron 350 antifouling is suitable for a wide range of substrates, including GRP, wood, steel and lead. However, it is not recommended for aluminium or galvanised surfaces. Application is simple and can be done by brush, roller or airless spraying.
