Muki Z 2001 is a two-pack, modified low zinc ethyl silicate shopprimer. Designed to utilize optimum productivity in connection with advanced welding technology (MIG/ MAG/G-FCAW) giving reduced weld defects/backburning. Muki Z 2001 is good in corrosion protection of steel during normal storage and fabrication, and reduces exposure to fumes during welding and cutting compared with medium to high zinc shopprimers. To be used as a preconstruction primer on blast-cleaned steel surfaces in automatic shop-priming plants to protect steel during transport, storage and production. For application on steel for water ballast tanks in accordance with PSPC (IMO Res. MSC 82/W), cleanliness must be: Dust - Min. rating 1, sizes 3,4,5 (ISO 8502-3:1993) and soluble salt - Maximum 50 mg/m² (ISO 8502-6 and- 9:1998).
