Description

This very fast-drying universal corrosion protection epoxy primer is "One for Everything": An exceptionally robust and waterproof 2-component sealant for use in underwater and above-water areas.
PPG SIGMAPRIME 200 has excellent corrosion protection properties, as well as high surface and temperature tolerance. It adheres to hand-derusted as well as water-blasted surfaces, just as well as to aluminum and hot-dip galvanized surfaces. 

Processing instructions: For sufficient corrosion protection in underwater areas, we recommend a dry film thickness of at least 200 μm; with roller application, this corresponds to approx. 4 coats. SIGMAPRIME 200 can be overcoated with all marine 1- and 2-component primers, paints and varnishes. Before painting with antifouling, an adhesion promoter (tiecoat) is required. For repairs and smaller boats, SIGMA VIKOTE 18 is used for this. For large-area coatings, SIGMACOVER 555 is recommended (available in 20 l containers on request).

Tip: The adhesion promoter (VIKOTE 18, SIGMACOVER 555) can be painted directly onto SIGMAPRIME 200 without sanding if the surface has not yet fully cured, i.e. is "tacky". Otherwise, intermediate sanding is necessary.

Technical data

  • Pretreatment:
    • Steel: blasting according to ISO-Sa2½ or mechanical cleaning (SPSS-Pt3), blast profile 30–75 µm
    • Shop primer: leave intact or, if damaged, also blast
    • Galvanized steel: degrease, roughen with sandpaper or sweep blasting
    • Old coatings: high-pressure cleaning, dry, clean, free of dust and grease
  • Subsequent coat: 2-component and 1-component primers (e.g. SIGMACOVER 555, SIGMADUR, VIKOTE 18) 
  • Coverage: approx. 6 m²/l at 100 µm (spray application), approx. 12 m²/l at 50 µm (manual roller application)
  • Thinner: THINNER 91-92 (brush/roller: up to 5 %, spraying: 0–15 %)
  • Application method: brush, roller, airless or air spraying
  • Mixing ratio: 4:1 (base:hardener by volume)
  • Pot life at 10°C: 7 hours 
  • Drying times at a DFT of up to 160 µm at 10 °C: touch-dry after 3 hours, dry for further processing after 8 hours, fully cured after 14 days
  • Shelf life: at least 24 months when stored cool and dry

HEMPEL LIGHT PRIMER Professional
HEMPEL LIGHT PRIMER is a high-quality 2-component epoxy primer for applications below and above the water. It can be used on rigid substrates as a barrier against penetrating water vapor, on GRP for osmosis prevention and repair, and on metal surfaces as corrosion protection. It can also be used on plywood and hardwood. Very suitable as an adhesion promoter for top coats and antifouling. Note: The 5-l containers of HEMPEL Light Primer are subject to specific transport and sales regulations and therefore cannot be shipped to private customers. Sale to private customers is only possible in-store after consultation in accordance with EU chemicals legislation (REACH/CLP)Technical DataSubstrate: GRP, plywood, steel, aluminium, existing coatingsSurface preparation:GRP: sand, cleanPlywood: seal with suitable sealerSteel: high-pressure fresh water wash, sandblast or mechanically remove rust and cleanAluminium: non-metallic abrasive blasting, degreaseOld coatings: sand, clean, dryPorous surfaces: prime first coat of Light Primer with 20% thinnerTopcoat: standard 1K and 2K products (see data sheet)Coverage: 8.2 m²/l at 60 µm dry film thicknessThinner: HEMPEL'S THINNER 845 (Art.No. 2577-022)Application method: Brush, roller, airless spray (professional use)Drying times at 10 °C: Dust dry after 6 hrs; recoatable after 9 hrsFurther information on application can be found in the technical data sheet under “Downloads”.
