LOCTITE PC 7282 - 1,5L EGFD (Polyurethane adhesive)

brak obrazka

Product description:
LOCTITE PC 7282 is a solvent-free, elastomeric, sprayable polyurea coating. It is designed for the protection of concrete, metal, and other materials against turbulence, chemicals, abrasive and corrosive agents. This product is flexible, crack bridging, and can be used to restore or protect against shocks, vibrations, distortions, or thermal expansions. Typical applications include rebuilding or resurfacing tank and container lining, structure protection for wear and tear parts, vibration stoker, stone chip protection, loading ramps, hoisting platform, truck bed lining, and flooring.

Directions for use:
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 ofcleanliness 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 Cleanerand 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: 10 to 40 °C.
● Relative humidity: <98 %; substrate temperature must always be 3 °C higher than the dew point.
● The metal and concrete (less than 10% moisture) surface is to be primed with Loctite 7462 or Loctite 7460. Please see technical information sheet of Loctite 7462 or Loctite 7460 for further instructions.
● Shake cartridge thoroughly before use.
● Pre-heat cartridge to 35 to 45°C before use.
● Minimum film thickness per coat: 1 mm.
● For recoat time or repairs more than 8 hours, Loctite 7460 solvent based is recommended to be used to prime existing polyuria coating before re-coating. Please see technical information sheet of Loctite 7460 for further instructions.

Storage:
Store product in the unopened container in a dry location. Material removed from containers may be contaminated during use. Do not return liquid to original container. Storage information may be indicated on the product container labeling. Optimal Storage: 10 °C to 30 °C. Storage below 10 °C or greater than 30 °C can adversely affect product properties.
