Kelate - Applications



On surfaces prepared to CSt2-DSt2 standards


KelateĀ® has been designed so that it will react and passivate (residual) rust on CSt2-DSt2 surfaces.


On partially de-rusted surfaces


Most mechanical surface treatments, such as scraping, hand brushing or power cleaning, do not remove all the rust from the cavities of the surface, and the presence of this residual rust encourages continuation of the corrosion process under paint films subsequently applied.


On blasted / white metal


Blasting the surface to white metal provides an excellent substrate for paint, but a freshly blasted surface is highly reactive, and once exposed to atmospheric humidity, dew or rain, will result quickly. This means that to preserve investment in sandblasting for instance, the freshly blasted surface must be coated immediately.


On surfaces which cannot be sandblasted


Sandblasting is often ruled out due to cost, environment protection, inconvenience of rigging, dust and spark potential, limited size of areas to be cleaned, difficulty of arranging blasting/painting cycles, etc.


On surfaces which cannot be chemically treated


Acid surface pre-treatment for corroded steel surfaces have shown limited advantage in relieving the problem.

Removal of the rust is extremely difficult under temperature, concentration and application conditions of the field.

Also in many situations, residual acids or salts left in the pores of the rust have caused failure by osmotic blistering of the paint system.

Even under the best field conditions, the use of conventional phosphoric acid based pre-treatment is also unsatisfactory.

Such products do not accomplish a true passivation of the metal surface, and their reaction with the different rust layers is not homogeneous and inefficient.


Typical applications



  • Ferrous surfaces such as railings, radiators, car bodies, etc..
  • Restoration of reinforced concrete steels (pillars, beams, balconies, facades, etc.)
  • Automotive: Ideal for small areas of rust, stone chips and scratches
  • Restoration of vehicles, machines and all kinds of facilities.
  • Marine: on all rusted steel surfaces before painting or repainting when preparation by sandblasting is a problem, e.g. cargo holds, decks, hatch covers, superstructures, pipelines, winches, rails etc.
  • On sandblasted surfaces to prevent or passivate "flash rust".
  • Etc ...
