PPG NovaGuard 260 is a two-component, high build, amine adduct-cured novolac phenolic epoxy primer/coating. Ideal as a tank coating with excellent resistance to alcohols, fats, solvents and various other chemicals. Produces a smooth and easy to clean surface due to its good application properties. For facilities that store hot water or oil, NovaGuard 260 is a great solution, so long as the water/oil temperature is not more than 90°C (195°F).

This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes.

Top Features & Benefits

• Used for hot water and hot oil storage up to 90°C (195°F)

Preparation & Application

Recommended Substrate Conditions & Temperatures

Substrate Conditions

• Steel; blast cleaned to a minimum of ISO-Sa2½
• Blasting profile 50 – 100 µm (2.0 – 4.0 mils)
• The substrate must be perfectly dry before and during application of NOVAGUARD 260

Substrate Temperature & Application Conditions

• Substrate temperature during application and curing should be above 5°C (41°F)
• Substrate temperature during application should be at least 3°C (5°F) above dew point

System Specification

For use as a holding primer

• NOVAGUARD 260: 50 to 75 µm (2 to 3 mils)

For use as a tank coating

• NOVAGUARD 260: 2 x 125 to 150 µm (5 to 6 mils)

Instructions For Use

Mixing ratio by volume: base to hardener 87:13

• 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

Additional Data

Notes:

• Maximum DFT when brushing: 60 µm (2.4 mils)
• Above 150 µm (6.0 mils) mudcracking can occur
• Highly pigmented zinc silicate primers produce dry films with void spaces in between the particles

Note:

Surface should be dry and free from any contamination

Notes:

• Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434)
• When used as a primer under solvent-free tank-linings the DFT must be limited to a maximum of 100 µm (4.0 mils)
