Loctite PC 7266-1kg (epoxy resin for metal corrosion protection, blue, to 101 °C


Product description:
LOCTITE PC 7266 sprayable epoxy is a solvent-free two part epoxy coating. It is designed to protect metal surfaces against abrasive and corrosive agents. It can be used as smooth, protective coating on metal surfaces. Typical applications are the protection of heat exchangers, condensers, lining tanks, valve bodies, pipes or pump impellers and housings.

Steps to achieve the best adhesive results:
Surface Preparation
Proper surface preparation is critical to the long-term performance of this product. The exact requirements vary with the severity of the application, expected service life, and initial substrate conditions.
● 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.
● 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 3mm and all corners must be likewise rounded to maximize product performance.
● Blast all surfaces to be coated with a sharp edged angular grit to a depth of profile of 75 to 100 microns (3 to 4 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.
● 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.
● 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. The procedure should be repeated until chloride concentration on the surface is below 40 ppm.

● Film thickness per coat: 75 to 100 microns (3 to 4 mils). Minimum of 2 coats is recommended to avoid any pin holes.
● Ambient and substrate temperature range: 15 to 30 °C (59 to 86 °F).
● Relative humidity: <85 %; substrate temperature must always be 3 °C (~5 °F) higher than the dew point.
● Suggested Spray Equipment: -- HPLV spray system with a pressurized pot at 1 bar (14 psi) and inlet air pressure at 6 bar (87 psi) (Recommended for the 1kg (2.2 lb) kit) -- Two component no premix equipment (Recomended for the 30 kg (66 lb) kit).
