Key properties

• An economical epoxy zinc-rich primer for various coating systems
• Good corrosion protection performance
• Fast drying, allowing the subsequent coat to be applied within a short time.
• May be used as a temporary protective primer in various coating system schemes for overall refurbishment projects
• The subsequent coat used for overcoating must be non-saponifying

Recommended substrate condition and temperature

Substrate condition

• Bare steel: abrasive blast clean to Sa 2½ (ISO 8501-1), with surface roughness of 40–70 µm (1.6–2.8 mils).

Substrate Temperature

• During application and curing, the substrate temperature must be above 10 °C (50 °F)
• During application and curing, the substrate temperature must be at least 3 °C (5 °F) above the dew point

Mixing ratio by volume: base : curing agent = 78 : 22

• Before application, raise the temperature of the components or the mixed paint to above 15 °C (59 °F); otherwise, thinner may need to be added to bring the paint viscosity

adjust to a state suitable for application.

• Excessive thinning may reduce the sag resistance of the wet film and slow curing.
• The thinner should be added after the two components are mixed

Induction Time

Not required

Air spray

Airless spray (single-feed pump)

Brush/roller

Supplementary parameters

Film thickness and spreading rate

Recoat interval for a coating up to 50 µm (2.0 mils) dry film thickness

Notes

• Zinc salts form on zinc-rich primer surfaces; before overcoating, the coating shall not be exposed outdoors for prolonged periods.
• In clean interior atmospheres, the interval before applying the next coat may extend to several months.
• If the coating is used in industrial and marine atmospheric environments, or where a long overcoating interval is required, it is recommended to apply a suitable

sealer as soon as the minimum overcoating time is reached.

• Before overcoating, any visible contamination on the surface shall be removed as appropriate, by high-pressure water washing, sweep blasting or power-tool cleaning

Notes

• Epoxy Zinc-rich 102 can be applied at temperatures as low as 5 °C (41 °F), but curing may be very slow
• Under such conditions, the following zinc-rich primer products are recommended: one-component Epoxy Zinc-rich Primer 19, Inorganic Zinc Silicate Primer 158, Inorganic Zinc Silicate Primer 160 are suitable

For atmospheric exposure under dry conditions; Inorganic Zinc Silicate 750 is suitable for immersed environments.

• During application and curing, ensure continuous, adequate ventilation (see Safety Sheet 1433 and Information Sheet 1434)

Pot life after mixing (at suitable application viscosity)

Safety Precautions

• For the coating and its recommended thinners, see Safety Sheets 1430 and 1431 and the relevant Material Safety Data Sheet
• This is a solvent-borne coating. Avoid inhaling spray mist and solvent vapours, and avoid contact of uncured paint with skin and eyes.
