Description

This very fast-drying universal epoxy primer is "one for all": an exceptionally robust and waterproof 2-component sealer for all boat building materials under and above water.
PPG SIGMA PRIME 200 has excellent corrosion protection properties as well as high surface and temperature tolerance. It also adheres to hand-rusted and water-blasted surfaces, as well as to aluminium and hot-dip galvanized surfaces. For good corrosion protection, we recommend applying at least 4-5 coats by roller.

Can be painted over with all maritime 1- and 2-component primers, paints and varnishes. An adhesion promoter (tiecoat) is required before painting with antifouling. SIGMA VIKOTE 18 is used for repairs and smaller ships. SIGMA COVER 555 (only available on request in 20 liter containers) is recommended for large-area coatings.

Tip: VIKOTE 18 can be painted directly onto SIGMAPRIME 200 without sanding if the surface is not yet fully cured, i.e. "tacky". Otherwise, intermediate sanding is necessary.
