- Description
- Technical specification
LOCTITE® PC 7332 Nordbak Wear Prevention Coating is a high performance, wet and dry abrasion resistant epoxy resin system. It is designed to protect, rebuild and repair high wear areas of processing equipment, such as desulfurization pumps and ducts, slurry pumps and pipes and slag granulation pumps which are subjected to severe wet abrasion. It can also be used for particle abrasion under dry conditions in transport elbows, chutes and other equipment. It is trowelable, non-sagging and requires no additional tooling.

How to use
Remove dirt, oil, grease, etc., with a suitable high pressure water cleaning system using LOCTITE® SF 7840™ (LOCTITE® Natural Blue® cleaner/degreaser).
Blast all surfaces to be coated with a sharp edged angular grit to a depth of profile of 75 to 100 microns, and a degree of cleanliness of Near White Metal (SIS SA 2½ /SSPC-SP 10).
After blasting, metal surfaces should be cleaned with a waterless LOCTITE® cleaner, e.g. LOCTITE SF 7365, SF 7063 or SF 7611 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. Otherwise, apply a thin coat of LOCTITE SF 7515 to all surfaces and allow to react for 1 minute. After 1 minute, blow off and dry the surface completely with clean and dry compressed air.
Measure 4 parts resin to 1 parts hardener by volume or weight. Transfer measured quantities or entire kit onto a clean and dry mixing surface and mix together with a trowel until uniform in color. If mixing larger quantities, a spiral mixing blade attached to a high torque electric or pneumatic drill can be used. 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 avoid air entrapment. Build up to desired thickness (minimum 6 mm), avoid air entrapment. At 25°C the working time is 30 minutes, and functional cure time is 7 hours. Working and cure time depend on temperature and mass - the higher the temperature and the larger the mass, the faster the cure.
FAQ
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 product description sheets.
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.
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 resin will remain unreacted and the physical properties of the product will be negatively affected.
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.
Functional cure time varies with product type and application temperature. Refer to the product description sheets for individual product information.
