Surface Preparation
Recommended Substrate Conditions and Temperatures
Immersion exposure
- Steel;
- Blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
- Steel with approved zinc silicate shop primer;
- Pre-treated according to SPSS-Ss
Atmospheric exposure conditions
- Steel;
- Pre-treated preferably to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils) or according to ISO-St3
- Shop primed steel;
- Pre-treated to SPSS-Pt3
Substrate conditions
- Previous coat (specific epoxy) must be dry and free from any contamination and within overcoating time
Substrate Temperature & Application Conditions
- Substrate temperature during application and curing should be above 5°C (41°F)
- Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
Application
Instructions for Use
Mixing ratio by volume: base to hardener 75:25 (3:1)
- The temperature of the mixed base and hardener should be above 10°C (50°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
Induction Time
None.
Pot life
- 2 hours at 20°C (68°F)

Airless spray
Recommended thinner
- THINNER 91-92
Volume of thinner
- 0 - 5%, depending on required thickness and application conditions
Nozzle orifice
- Approx. 0.48 – 0.53 mm (0.019 – 0.021 in)
Nozzle pressure
- 15.0 MPa (approx. 150 bar; 2176 p.s.i.)

Safety Precautions
- For paint and recommended thinners, see information sheets information sheet 1430, information sheet 1431 and the relevant Material Safety Data Sheets in the attachments section above
- This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapour, as well as contact between the wet paint and exposed skin or eyes
