To help engineers cut downtime, improve equipment performance and save costs, Henkel offers a wide range of Loctite®, Nordbak® and Hysol® products for repair and maintenance. They are designed to rectify problems caused by wear, abrasion, chemical attack, erosion, corrosion, impingement and mechanical damage. Typical applications range from concrete repair to extending the operating life of devices like pumps, gearboxes and centrifuges.
Flow control mechanisms and influent structures are particularly prone to wear and corrosion making them less effective and susceptible to leaks and further damage. Components such as butterfly valves or grit chamber paddles and spindles are typical examples.
They can be rebuilt or re-profiled by the application of Nordbak® epoxy wearing compounds or Hysol® polymer composites and/or Loctite® brushable ceramics. Henkel points out that the key advantage is their capability to create a sacrificial and renewable working surface, protecting the structural integrity of the original substrate.
Loctite® threadlockers are widely used in the water utilities industry for preventing vibrational loosening, leakage and corrosion between threaded and parts. They are available in a range of viscosities and also strengths, from semi-permanent formulations to those that are removable with standard hand tools.
Typical applications are bar screen and clarifier components which will loosen under high duty cycles requiring periodic shut downs for surface repairs and retightening of the threaded assemblies.
Costly hydraulic and pneumatic leaks are eliminated using Loctite® sealants. They fill the space between threaded parts providing an instant, low pressure seal. When fully cured they seal to the burst strength of most pipe systems.Anaerobic, silicone and sealing cord are available to suit the substrate.
Complementing the threadlockers and sealants are Loctite® retaining compounds that secure bearings, bushings and cylindrical parts into housings or onto shafts. They achieve maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion.
