PPG - Phenguard 940 - Epoxy Topcoat Finish is part of the leading SigmaGuard range that acts as a Finish coat in the PHENGUARD tank coating system.

Features

• Excellent resistance to a wide range of organic acids, alcohols, edible oils, fats (regardless of free fatty acid content) and solvents
• Maximum cargo flexibility
• Low cargo absorption
• Good resistance to hot water
• Recognized corrosion control coating (Lloyd's register)
• Good application properties, resulting in a smooth surface
• Easy to clean

Recommended Substrate Conditions and Temperatures

Substrate conditions

• Previous coat (PHENGUARD 935) must be dry and free from any contamination
• The substrate must be perfectly dry before and during application of PHENGUARD 940 Substrate temperature and application conditions 
• Substrate temperature during application and curing should be above 10°C (50°F)
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

Instructions For Use

Mixing ratio by volume: base to hardener 88:12

• The temperature of the mixed base and hardener should preferably be above 15°C (59°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
