LeFANT NAUTICA HARD ECO biocide free antifouling

The LEFANT Epoxy Primer is specially designed for underwater use and can be applied to gelcoat, plastic, steel, aluminum, Z-drives and propellers. The two-component epoxy resin-based primer is suitable for the pre-treatment of antifoulings such as LEFANT T-Coat, it is oil and chemical resistant, protects the hull against the penetration of moisture and thus prevents osmosis. Thanks to the long overcoating intervals, it is easy to apply and cures even at low temperatures (min. 5 °C). Available in white or black.Application on painted substrates: Old one-component coatings and primers should be removed, two-component primers in good condition can be roughly sanded (grain size 60-80). Then clean thoroughly. If necessary, level out uneven areas with epoxy filler.When recoating steel hulls, the surface should be sandblasted or roughly sanded and painted with a thinned coat of epoxy primer (20-30% thinned with Lefant Multi-Thinner) immediately after sanding. Then apply up to three further coats and level out any unevenness and imperfections with filler.Technical DataSubstrate: GRP, steel, aluminium, plywood, existing 2C epoxy primersSurface preparation:GRP: remove release agents, sand (grit 80), degreaseSteel/aluminium: sandblast or sand (grit 40/80), degreaseWood: sand (grit 80), cleanExisting primer: sand (grit 80), cleanFollow-up coat: LEFANT antifoulingsCoverage: approx. 8 m²/l at 50 µm, 2 m²/l at 200 µm, 1.33 m²/l at 300 µmThinner: LEFANT Multi Thinner 3087 (only for first coat on metal or spray application)Application method: Short mohair roller, spray (professional use)Mixing ratio: 4:1 (Base:Hardener by volume)Pot life: 8 hrs at 20 °CDrying times at 18 °C: Recoatable after 12 hrs, antifouling after 3–5 days (depending on temperature/system), fully durable after 7 daysFurther information on processing can be found in the technical data sheet under “Downloads”.
