PPG PSX 700 product is a proven, patented technology that provides long-term protection, with application and system capabilities that can lower the cost of ownership for valuable steel assets.

Features

• Unique, high gloss, isocyanate free solution
• Can be applied directly over inorganic zinc
• Excellent color and gloss retention 
• Resists graffiti
• High solids, VOC compliant
• Applied by brush, roller or spray, without thinning
• Good resistance to splash and spillage of chemicals
• Can be applied as a single coat, direct-to-metal for moderately corrosive environments (ISO 12944 C1-C3)

Recommended Substrate Conditions And Temperatures

• Coating performance is proportional to the degree of surface preparation

Substrate Conditions

• Steel; pre-treated minimum ISO-Sa2 (SSPC SP-6) or higher with blasting profile 25 – 75 µm (1.0 – 3.0 mils)
• For touch up and repair, power tool cleaning in accordance with SSPC SP-11 is acceptable
• Galvanized steel; sweep blasted to roughen the surface to remove any zinc salts which might be present, SSPC SP-16 with blasting profile 40 – 75 µm (1.5 – 3.0 mils)
• Stainless steel and non-ferrous metal; degreased and sweep blast, SSPC SP-16 with blasting profile 40 – 100 µm (1.5 –4.0 mils)
• Concrete / Masonry; see specific primer
• Compatible previous coat must be dry and free from any contamination
• When applied to zinc silicate primer, a mist coat and full coat technique is required. 15% thinning is recommended for mist coat
• Aged suitable coating must be dry and free from any contamination, it may require abrading prior to applying this product
• Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating

Substrate temperature

• Substrate temperature during application and curing should be above 0°C (32°F)
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
• Relative humidity during application and curing should be between 40% and 80%
• Note: FD hardener should be used when ambient temperature is below 5°C (40°F)

Brush/roller

• The recommended DFT cannot be reached in one coat
• Use a high quality natural bristle brush and / or solvent resistant, short nap roller. Ensure brush / roller is well loaded to avoid air entrainment
• Maintain a wet edge Cleaning solvent THINNER 90-53 or THINNER 60-12 (AMERCOAT 911)
