PPG SteelGuard 751 is a one-component thin-film solvent-borne intumescent coating for fire protection of structural steelwork. Provides up to 120 minutes protection from cellulosic fires.

Top Features & Benefits

• Off-site or on-site application
• Up to 1500 µm (60.0 mils) DFT in a single coat
• Suitable for C1 to C4 internal and external environments (ISO 12944); for dry internal (C1) environments no topcoat is required
• Weather resistant up to 12 months without topcoat provided the coating has been applied in accordance with INFORMATION SHEET 1222 and is not subject to running or pooling water, high humidity or immersion conditions
• Tested and assessed to EN 13381-8, BS 476-20/21 and AS 1530.4
• CE marked product, ETA 15/0439
• Assessed to ETAG 018-2 for all durability classifications

Product Data

Recommended Substrate Conditions and Temperatures

• Approved primer must be sound, dry and free from any contamination
• Substrate temperature and application conditions
• Substrate temperature during application and curing should be between 5°C (41°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 5°C (41°F) and 40°C (104°F)
• Relative humidity during application and curing should not exceed 85%

Instructions for Use

• Stir thoroughly until homogeneous and free of lumps
• Adding too much thinner results in reduced sag resistance and slower cure
