Recommended substrate condition and temperature

Substrate condition

• Steel: abrasive blast cleaning to Sa2½ of international standard ISO 8501-1, surface profile 50–100 µm (2.0–4.0 mil)
• The substrate surface must be clean, dry and free of all contaminants.

Substrate temperature and application conditions

• During application, the substrate surface temperature must be maintained at least 3 °C (5 °F) above the dew point.
• During application and curing, the substrate temperature must be above 5 °C (41 °F)

Instructions for use

Mixing ratio by volume: base : curing agent = 80 : 20

• The temperature of the base component shall reach at least 40°C (104°F) during mixing
• At low temperatures, spraying may be difficult because of high paint viscosity.
• Do not add thinner

Pot life after mixing

30 min at 20 °C (68 °F). Note: refer to supplementary data — pot life

Airless spray (single-feed pump)

• An externally heated two-component airless spray pump
• For low-temperature application, use heated or insulated hoses to prevent the paint from thickening in the lines.
• Keep hoses as short as possible

Nozzle tip size

Approx. 0.53 mm (0.021 in)

Brush/roller

• For local small-area repair and manual touch-up only

Notes

• All application equipment must be cleaned immediately after use
• Paint remaining in spray equipment must be fully discharged within its pot life.

Supplementary parameters

Film thickness and spreading rate

Note: maximum dry film thickness for brush application: 150 µm (6.0 mil)

Wet film thickness measurement

• Differences between wet film thickness readings and the actual film thickness frequently occur on site, because the thixotropic properties and surface tension of the paint and air entrained in the paint

escape slowly and usually remain within the wet film for a period, temporarily occupying part of the coating volume.

• It is recommended to control the wet film thickness at the rated dry film thickness plus 60 µm (2.4 mil) during application

Measure dry film thickness

• Because the coating has low initial cure hardness, a film thickness gauge probe sinks into the film and gives inaccurate readings if dry film thickness is measured in the first few days.
• When measuring dry film thickness, place a calibration shim of known thickness over the coating at the test point, then gently press the gauge probe onto the shim to measure the film thickness through it.

the maximum overcoating interval. Note: the surface shall be clean and dry, with all contamination removed.

Curing time table for a coating with a dry film thickness of 600 µm (24.0 mil)

Note: although this is a solvent-free coating, adequate ventilation is required during application and curing (refer to Tables {1433} and {1434}); pot life (at a viscosity suitable for application)

Note: as the reaction is exothermic, the paint temperature may rise during mixing and for a period afterwards

Safety Precautions

• For the coating and its recommended thinners, see Safety Sheets 1430 and 1431 and the relevant Material Safety Data Sheet
• Although a solvent-free coating, it shall be handled with care; avoid inhalation of spray mist and contact of wet paint with skin or eyes
• In confined spaces, provide adequate ventilation to maintain good visibility.
