High Impact Wearing Compound
LOCTITE® PC 9313
Product category: Wear resistant coatings
- Technical specifications
LOCTITE® PC 9313 Nordbak® Wear Prevention Coating is an impact resistant epoxy resin system superior to ceramic tile. Recommended for lining and protecting flumes, troughs, elbows, hoppers, discharge chutes, and other processing equipment that is exposed to both abrasion and impact. It is trowelable and requires no additional tooling.
Cures to ceramic hardness – resists sliding abrasive wear
Won’t sag or shrink – conforms to overhead and irregular
surfaces, application versatility
Renews worn surfaces fast – reduces downtime
Impact resistant – resists mild impact at 45° angles
Offers the wear resistance properties of an epoxy along with impact resistance

How to use
Remove dirt, oil, grease, loose flaky rust, etc., with a suitable high pressure water cleaning system using LOCTITE® SF 7840 Natural Blue® cleaner/degreaser.
Blast all surfaces to be coated, with a sharp edged angular grit, such as aluminum oxide, to a depth of profile of approximately 75 microns, and a degree of cleanliness of Very Thorough Blast Cleaning/Near White Metal (ISO 8501-1 SA 2½ /SSPC-SP 10).
After blasting, metal surfaces should be cleaned with a waterless, or solvent based LOCTITE® cleaner, such as LOCTITE SF 7611 or SF 7633, and allow the surface to dry before application of the product. Coat the surface before any oxidation or contamination takes place.
To avoid flash rust, repairs should be made as soon as possible or within a maximum 2 hours of blasting. Otherwise, apply a thin coat of LOCTITE SF 7515 to all surfaces and allow to react for 1 minute. After 1 minute, blow off with clean and dry compressed air until the surface is completely dry.
Measure 2 parts resin to 1 part hardener by volume or weight if doing a partial kit. Otherwise, mixing a full kit is pre-measured at the correct ratio. For a full kit mix, a spiral mixing blade attached to a high torque electric or pneumatic drill can be used. For a partial kit, transfer measured quantities onto a clean and dry mixing surface to mix together with a trowel until uniform in color. If resin and hardener temperatures are 15°C or below, preheat resin only, to about 30°C but not to exceed 40°C .
Apply fully mixed material to the prepared surface. Initially apply the material in a very thin layer to "wet" out the surface and ensure full epoxy contact with the roughened surface. Build up to desired thickness (minimum 6 mm), avoiding air entrapment. At 25°C, the working time is 15 minutes and functional cure time is 4 hours. Working and cure time depend on temperature and mass - the higher the temperature and the larger the mass, the faster the cure.
A successful application is largely dependent on surface preparation. The application surface must be free from all contamination. Removal of oil, grease, dust, rust and, for most products, moisture, will greatly enhance application success. For more detailed surface preparation techniques, refer to the product description sheet.
If a part is cold and the ambient air is warm, cure time will be extended. Both the air and the part should be at room temperature to get the prescribed cure time and strength. Also, the surface temperature should be a minimum of 5°F (-15°C) above the dew point.
No. Epoxy systems have been formulated to contain an exact amount of resin to react with an exact amount of hardener. If excess hardener is added, the final cured product will perform differently from the properties on the technical data sheet.
The use of solvent is not recommended due to the possibility of trapping the solvent in the cured systems, causing voids or soft spots.
Yes, polymer composites are packaged as kits in the exact ratio required. Partial kits, however, can be mixed if measured precisely by weight or by volume.
Functional cure time varies with product type and application temperature. Refer to the product description sheets for individual product information. For LOCTITE PC 9313 cured at 70°F/21°C, the functional cure time is 6 hours. Warmer conditions will shorten this time and colder temperatures will add to this time.
