Basic data

Parameters after mixing

Curing agent: at least 12 months; store in a dry and cool environment.

Notes

• The coating should be stored in a dry environment, not exposed directly to sunlight, at an ambient temperature of 0 °C (32 °F) to 30 °C (86 °F).
• The density of the finished coating is subject to various factors such as temperature, test method, application method and application equipment.
• The rated dry film thickness of the coating shall comply with the requirements of the product approval certificate.
• Application consumption shall allow for a loss factor.

Recommended substrate condition and temperature

• In accordance with the STEELGUARD 951 application guide, a compatible primer must be used; the coating must be sound, clean and dry, with all contaminants removed.
• Surface preparation in accordance with the Application Guide; also suitable for galvanised surfaces.

Substrate temperature and application conditions

• The extreme conditions under which PPG STEELGUARD 951 can be applied and cured are (all the following thresholds apply during both application and curing):
• Substrate temperature: minimum 5 °C (41 °F), maximum 60 °C (140 °F), and at least 3 °C (5 °F) above the dew point.
• Relative humidity: maximum 70%.
• Ambient temperature: above 10 °C (50 °F) and not exceeding 45 °C (120 °F).

Notes

• For ideal and preferred environmental conditions, refer to the PPG STEELGUARD 951 Application Guide. Environmental conditions must be monitored throughout application and curing, as weather conditions can vary greatly. If ideal environmental conditions cannot be met or maintained, or deviations are expected, consult PPG.

Instructions for use

• The application process must follow the PPG STEELGUARD 951 Application Guide.
• Each component must be stored at 20-25 °C (68-77 °F) for at least 24 h before use.
• Each component must first be stirred separately to a homogeneous state, leaving no lumps.

Mixing ratio

• Volume mixing ratio: base : curing agent = 3.0:1 (75.0:25.0).
• Weight mixing ratio: base : curing agent = 3.56:1 (78.07:21.93).

Notes

• Tolerance: +/- 5%.
• When applying with a single-component pump or trowel, it is recommended to mix the entire kit at once.

Airless spray - two-component spray pump

Spray fan angle

40°, for large flat surfaces.

Notes

• For more details, refer to the PPG STEELGUARD 951 application guide

Airless spray - single-component spray pump

Notes

• For more details, refer to the PPG STEELGUARD 951 application guide

Trowel

Notes

• For more details, refer to the PPG STEELGUARD 951 application guide
• It is recommended to mix all components of the entire kit at once (to avoid proportion errors when mixing the remaining components later).
• Recommended only for small-area application, local repair and stripe coating.

Cleaning solvent

• Thinner 91-92

Supplementary parameters

Recoating time for a coating with a maximum dry film thickness of 3500 µm (138 mil) without any thinner added

Curing time of the coating applied without any added solvent

Notes

• Adequate and continuous ventilation must be maintained during application and curing of the coating.
• The actual curing time may also vary with the temperature of the substrate, environment and paint.
• Curing time and recoating interval apply to the unthinned product. Once the product is thinned, both times will necessarily be extended.

Safety Precautions

• Although solvent-free, the coating must be handled with care; avoid inhaling spray mist and contact of uncured paint with skin and eyes.
• Read all labels and the safety data sheet carefully before use
