PPG Sigmacover 630

Description

PPG Sigmacover 630 is a two-component, surface-tolerant, high-build, polyamide-cured epoxy primer/coating.

PRINCIPAL CHARACTERISTICS

Ø  Epoxy mastic.

Ø  Surface tolerant coating for lower grade of steel preparation.

Ø   Particularly suited as maintenance coating for dry cargo holds, decks and hulls.

Ø  General-purpose epoxy buildcoat or finish in protective coating systems, for steel and concrete structures exposed to atmospheric land or marine conditions.

Ø  Compatible with various aged coatings.

Ø  Overcoatable with most types of coatings.

Ø   Excellent corrosion resistance.

Ø  Resistant to splash and spillage of a wide range of chemicals .

Ø  Good flexibility

RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

Atmospheric exposure conditions

Ø  Steel; blast cleaned to ISO-Sa2½, for excellent corrosion protection.

Ø  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.

Ø  Shop primed steel; pretreated to SPSS-Pt3.

Ø  Coated steel; hydrojetted to VIS WJ2/3L.

Ø  Existing sound coating systems; sufficiently roughened, dry and cleaned Immersion in water with cathodic protection

Ø  Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils).

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

Ø  First coat SIGMACOVER 630 aluminum.

 Substrate temperature.

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

Ø  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.
