Antiosmotic HS Epoxy Primer 3:2

This particular product is recommended for protecting the laminate below the waterline, especially for repairing laminate affected by osmosis. Epoxy HS primer is a thick-layer epoxy primer designed to repair hull bottom damage.

The product is non-solvent-based, which means it does not contain solvents that could react with substances present in laminate damaged by osmosis, for example. Osmosis repair is a specific process that requires not only the right primer but also proper preparation and repair conditions. The product cures in 24 hours at around 20ºC.

Our FAQ answers to frequently asked questions

There is a possibility of thinning antifouling, but we do not recommend this procedure due to the risk of reducing the effectiveness of the paint. If it is necessary to thin the antifouling paint, it is recommended to dilute it to a maximum of 0-5% (by volume).

Sea-Line HARD and Sea-Line self-polishing antifouling are not intended for aluminum surfaces. They include copper oxide, which in contact with aluminum causes galvanic corrosion. Especially on aluminum, we offer ALU-PLUS self-polishing anti-fouling paint, which, in addition to excellent adhesion to aluminum, is also 30% more effective than traditional anti-fouling paints.

Yes, you can mix Sea-Line polyurethane paints. The only difference are the pigments of polyurethane paints that determine the color of the paint. But remember to keep the right proportions of base, hardener and thinner.
