SIGMACOVER 630 SIGMA PROTECTIVE AND MARINE COATING

RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

Atmospheric exposure conditions

• Steel; blast cleaned to ISO-Sa21⁄2, for excellent corrosion protection

• Steel; blast cleaned to ISO-Sa2, blasting profile 40 – 70 μm (1.6 – 2.8 mils) or power tool cleaned to ISO-St2 for good

  corrosion protection

• Shop primed steel; pretreated to SPSS-Pt3

• Coated steel; hydrojetted to VIS WJ2/3L

• Existing sound coating systems; sufficiently roughened, dry and cleaned

  Immersion in water with cathodic protection

• Steel; blast cleaned to ISO-Sa21⁄2, blasting profile 40 – 70 μm (1.6 – 2.8 mils)

• Steel with approved zinc silicate shop primer; sweep blasted to SPSS-Ss or power tool cleaned to SPSS-Pt3

• First coat SIGMACOVER 630 aluminum

Substrate temperature

• Substrate temperature during application and curing should be above 10°C (50°F)

• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

INSTRUCTIONS FOR USE

• Mixing ratio by volume: base to hardener 83:17
• The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
• Adding too much thinner results in reduced sag resistance and slower cure

• Thinner should be added after mixing the components

• Induction time None
• Pot life 2 hours at 20°C (68°F)

Frequently Asked Questions

1. Can I use the same paint on the hull and topside areas?

The hull and topside areas have different requirements, so it's recommended to use specific paints designed for each area. Hull paint is typically formulated for underwater use and has antifouling properties, while topside paint is more suitable for above-the-waterline areas.

2. How can I maintain the painted surfaces on my boat?

Regular maintenance is crucial to extend the life of the painted surfaces on your boat. This includes cleaning the surface regularly, avoiding harsh chemicals or abrasive materials, addressing any damage or scratches promptly, and applying touch-ups or recoating as necessary.

3. Can I use marine paint for non-marine applications?

Marine paint is specifically designed for marine environments and may not be suitable for non-marine applications. However, some marine paints can be used for other applications such as outdoor furniture or metal structures, depending on the specific product and manufacturer's recommendations.
