Application Notes

Recommended Substrate Conditions and Temperatures

• Approved primer must be sound, dry and free from any contamination
• Substrate temperature during application and curing should be between 10°C (50°F) and 40°C (104°F)
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
• Ambient temperature during application and curing should be between 10°C (50°F) and 40°C (104°F)
• Relative humidity during application and curing should not exceed 80%

Instructions for Use

• Stir thoroughly until homogeneous and free of lumps
• Adding too much water results in reduced sag resistance and slower cure
• Must be protected from freezing at all times during storage and/or transport

Airless Spray

• Recommended thinner: Tap Water (normally no thinner required)
• Volume of thinner: 0 - 5%
• Nozzle angle: 20° – 50°, depending on shape of steel parts
• Nozzle orifice: Approx. 0.43 – 0.53 mm (0.017 – 0.021 in)
• Nozzle pressure: 20.0 MPa (approx. 200 bar; 2901 p.s.i.)

Notes: All filters, including surge bottle and gun filters to be removed. External fluid uptake pipe filter is recommended.

Brush/Roller

• For small areas only (touch up and repair)
• No thinner should be added

Cleaning Solvent

• Tap Water

Product Data & Drying Times

Note : Maximum DFT when brushing : 300µm (12.0 mils)

Notes:

• All overcoating times have been measured at an intumescent wet film thickness of 1000µm (approx. 700µm DFT) under controlled temperature and relative humidity below 85%. Higher thicknesses will take longer to cure
• The system should be dry to handle and a coating thickness gauge should not leave an indentation on the surface prior to applying subsequent coats
• Curing time(s)/overcoating interval(s) may be extended at higher applied DFT’s and/or there is a change in environmental conditions
• Prior to application of a topcoat, the applicator must ensure that the specified dry film thickness has been achieved

Note: All curing times have been measured at an intumescent wet film thickness of 1000µm (approx. 700µm DFT) under controlled temperature and relative humidity below 85%. Higher thicknesses will take longer to cure
