LOCTITE SF 7462 - 1L EGFD (Polyurethane primer, solvent free) (IDH.2231060)

Product description:
LOCTITE SF 7462 is a one component, solvent free, polyurethane based primer. It is designed to prime metal or concrete surfaces before polyurea coating products like Loctite PC 7280 or Loctite PC 7282. This product hardens in thin layers by absorbing the humidity from the air or from the substrate in the case of concrete. This wear and impact resistant film is visible under UV light.

Product description:
Surface Preparation:
1. Remove dirt, oil, grease etc with a suitable cleaner, e.g. high pressure water cleaning system using LOCTITE SF 7840 or Loctite Natural Blue cleaner/degreaser.
2. All skip welds, weld splatter, buckshot, and other surface roughness must be ground down and smoothed; undercuts and pinholes must be ground smooth and filled. All projections, sharp edges, high points and fillets must be ground smooth to a radius of at least 3 mm (metal) and 6 mm (concrete) and all corners must be likewise rounded to maximize product performance.
3. Blast all surfaces to be coated with a sharp edged angular grit to a depth of profile of ≥60 microns ( mils), and a degree of cleanliness of Near White Metal (SIS SA 2½ /SSPC-SP 10). For immersion service, a degree of cleanliness of White Metal (SIS SA 3/SSPC-SP 5) is required.
4. After blasting, metal surfaces should be cleaned, e.g. with LOCTITE SF 7063 or Loctite ODC Free Cleaner and Degreaser, and be coated before any oxidation or contamination takes place.
5. Metal that has been in contact with salt solutions, e.g. seawater, should be grit blasted and high-pressure water blasted, left for 24 hours to allow any salts in the metal to sweat to the surface. A test for chloride contamination should be performed.

Application:

● Ambient and substrate temperature range: 5 to 35 °C.
● Relative humidity: <98 %; substrate temperature must always be 3 °C higher than the dew point.
● Ideal product application is to use roller or air pressure / airless spray. The compressed air needs to be free of oil and water.
● Minimum film thickness per coat: 30 to 100 µm.
● This primer must be tack free before applying the coating LOCTITE PC 7280 or Loctite PC 7282.
● Maximum recoat time is 48 hours.
