Surface Preparation
Recommended Substrate Conditions and Temperatures
Substrate conditions
- Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 1.8 mils), or power tool cleaned to ISO-St3
- Compatible previous coat must be dry and free from any contamination
Substrate Temperature & Application Conditions
- Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
- Substrate temperature during application and curing down to -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
- Relative humidity during application and curing should not exceed 85%
- Premature exposure to early condensation and rain may cause colour and gloss change
Application
Instructions for Use
Mixing ratio by volume: base to hardener 87:13
- Do not thin more than is required by appropriate application property
- Adding too much thinner results in reduced sag resistance
- Thinner should be added after mixing the components
Induction Time
None.

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
- Contains a toxic polyisocyanate curing agent
- Avoid at all times inhalation of aerosol spray mist
