Product description:
Nordbak Wearing Compound Loctite 7218 is a two-component epoxy paste with a ceramic filler.
It is intended for protection, reconstruction and repair of heavily used areas in utility devices.
Working temperature range: -30 oC to +120 oC.
Benefits:
• Ceramic filler for excellent abrasion resistance
• Fast regeneration of worn surfaces - reduces downtime
• Increases wear resistance of sliding surfaces saves costs of purchase of new parts
• Does not settle - provides abrasion resistance on ceiling and vertical surfaces
Typical applications:
• Cases for cyclone separators and separators
• Dust collectors and exhaust fans
• Pump linings and impellers
• Fan blades and casings
• Chutes and hoppers
• Elbows and fittings.
Application instructions:
Surface preparation:
Proper surface preparation is important for product durability. Strict requirements vary depending on the accuracy of the workmanship, the expected service life and the initial condition of the material.
• Thoroughly clean and sand the surfaces (if possible blast) then wash them with Loctite 7063. The more thorough the surface preparation, the better the application effect.
• Before applying agent 7218 on metal vertical and ceiling surfaces, it is recommended to weld a series of short metal mesh welds.
Mixing:
• Measure 2 portions of resin and one portion of hardener, by volume or by weight, transfer them to a clean and dry color.
• If the temperature of the resin or hardener is 15 ° C or less, heat the resin to approximately 30 ° C, but do not exceed 40 ° C.
Application:
• Apply the mixed material to the prepared surface.
• Apply a thin layer first to obtain a dry surface.
• Form the required thickness (minimum 6mm); Avoid trapping air in it.
• At 25 ° C, the pot life is 30 minutes and functional hardening is 7 hours.
• Attention! When welding or cutting the torch near a cured product, use an approved, air-fed respirator. DO NOT POINT an open flame on this material.
Storage:
Unless otherwise indicated on the product label, an ideal way of storing it will be to keep it in closed containers in a cool and dry room between 8 ° C and 28 ° C. The optimal storage temperature is the lower half of this range.
The remaining material should not be placed back in its original container, as the product may become contaminated. Further information on the shelf life of the product can be obtained from your local Technical Service Center.
