LOCTITE PC 7337 PART B - 0.333 kg (ultra-smooth ceramic anti-stick coating with increased abrasion resistance, up to 150 °C)
Product description:
LOCTITE® PC 7337™ is a two component ultra-smooth, low surface energy, hydrophobic, anti-stick coating with increased abrasion resistance and lower viscosity for a thinner coating. LOCTITE® PC 7337™ is designed to protect surfaces against sticking of fine particles which can result in frequent equipment downtime for cleaning or dynamic unbalancing & wear of rotating equipment. Its low surface energy & excellent adhesion on clean surfaces increases efficiency of equipment and long-lasting protection. Typical applications includeprotecting induced/forced draught fan impellers, blowers, fan housings, material handling buckets, chutes, hoppers, idler, & air ducts etc. Further information about the product: biuro@woronko-kleje.pl
Directions for use:
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® cleaner/degreaser.
● All skip welds, weld spatter, buckshot, and other surface roughness must be ground down; undercuts and pinholes must be ground and filled. All projections, sharp edges, high points and fillets must be ground 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 40 to 60 microns (2 to 3 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. Alternately power tool cleaning methods can be used such as bristle blasting, buffing or equivalent for less severe applications.
● After blasting, metal surfaces should be cleaned, e.g. with a LOCTITE® solvent based, residue free cleaner, 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. Theprocedure should be repeated until chloride concentration on the surface is below 30mg/m³ (3µg/cm³). Then blast and clean thesurface as described on point 3 and 4 above.
Application:
● Add hardener content to Resin in a mixed ratio of 100:50 by weight (100 :75 by volume), mix it thoroughly until the uniform color is obtained.
● Film thickness per coat: 250 microns (8 mils). Single coats is recommended without any pin holes.
● Additional coat application may be carried out within the recoat time, If final thickness cannot be achieved or any void spot or pinholes are observed or if surface is pitted. If this time has elapsed, light abrasive scratching is required, followed by a solvent wash to remove any abrasive residues.
● Ambient and substrate temperature range: 15 to 40 °C (59 to 104 °F).
● Relative humidity: 85 %; substrate temperature must always be 3 °C higher than the dew point.
● Cure time is 24 hours.
● Apply material to prepared surface by first forcing a thin layer deep into the texture of the substrate.
● Then immediately build up to the desired finished thickness
Inspection:
● Visually inspect for pinholes and voids just after application.
● Once the coating has cured, repeat visual inspection to confirm absence of pinholes, voids or damaged areas.
● Control thickness of the coating, especially in the critical areas.
● Perform a test with a holiday detector to confirm coating continuity.
Color:
● Color variation is possible between the batches and will not affect the performance of the product.
Coverage:
To achieve a 0.25 millimeter ( 10 mils) thickness, the coverage rate will be 2.6 m² (28 ft²) for 1 kg (2.2 lb), excluding overthickness,repairs, etc.
Repairs:
Any voids, pinholes, or low thickness areas found in the coating should be repaired by lightly abrading, cleaning, and applying further product.
Clean-up:
Immediately after use clean tools with a Loctite® solvent base cleaner. Once cured, the material can only be removed mechanically.
Storage:
Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Material removed from containers may be contaminated during use. Do not return product to the original container. Henkel Corporation cannot assume responsibility for product which has been contaminated or stored under conditions other than those previously indicated. If additional information is required, please contact your local Henkel representative.
