SEAJET 021 EKO

SEAJET 021 EKO – biocide-free antifouling Self-polishing antifouling free of biocides and copper, kinder to the environment SEAJET 021 EKO is a self-polishing antifouling for the underwater hull that contains no biocides. Rather than relying on toxic substances, it works through controlled erosion: in contact with water, the surface layer of the coating slowly hydrolyses and is constantly renewed, so algae, barnacles and other fouling find it hard to attach permanently to the hull. The coating wears away evenly while under way and keeps the surface smooth throughout the season. It is suitable for owners who want more environmentally friendly protection, especially for boating on inland waters (lakes, rivers) and in areas with moderate fouling. Advantages Free of biocides and copper – kinder to the aquatic environment Self-polishing action – the surface is constantly renewed, with no build-up of old layers For all substrates, including aluminium – GRP, wood, steel and aluminium (with the correct primer) For fresh and salt water For boats up to 40 knots Up to one season of protection with two coats Technical data Colours: white, black, dark blue (navy) Pack sizes: 0.75 l / 2.5 l / 5 l / 20 l Coverage: approx. 10 m²/l per coat (theoretical, at 40 µm dry film) Film thickness: 100 µm wet / 40 µm dry per coat Application: brush, roller; spraying for professional use only Thinner: SEAJET Thinner A (0–5 %) Application temperature: air 5–35 °C, substrate 7–35 °C Shelf life: at least 2 years at 20 °C Drying times (at 20 °C and 40 µm) Touch dry: 1 hour Fully dry: 4 hours Recoat: after at least 7 hours Launching: after at least 12 hours Recommended coating system GRP and steel: 3 coats of SEAJET 117 Epoxy Primer (silver) + 2 coats of SEAJET 021 EKO Wood: 2 coats of SEAJET 015 Underwater Primer + 2 coats of SEAJET 021 EKO Aluminium: 3 coats of SEAJET 117 Epoxy Primer + 2 coats of SEAJET 021 EKO Over existing antifouling: clean the surface, check compatibility and apply 1 coat of SEAJET 015 as a barrier coat Directions for use 1. The surface must be clean, dry and free of grease, salt and fouling. Lightly sand the old coating and remove the dust. 2. Stir the paint thoroughly before use. 3. Apply at least 2 coats. Apply an extra coat to exposed areas – the leading edge of the keel, the waterline, the rudder and the drive units. 4. Observe the recoat interval and the minimum time before launching. Tip Drying times are longer at low temperatures and high humidity. For areas with heavy fouling (e.g. warm seas), consider a stronger biocidal antifouling.
