High Performance Coatings

640 Permanent Protector

These are highly advanced SiO² coatings which were created to address the needs of the marine, military and aerospace sectors. They are massively resistant to corrosion, abrasion and temperature. They can be applied to metal, plastic, powder coated and painted substrates. The coatings can be heat cured, or cured at ambient temperature. 640 Permanent Protector react with the substrates surface and form an abrasion resistant coating with very high bonding properties on metal. They generate thin, transparent coatings with high impact strength and is resistant to alkali, abrasion and corrosion.

ALGT© Corrosion Protection

Use on materials such as

  • Ferrous metals
  • Non ferrous metals
  • Galvanised metals
  • Varnished surfaces
  • Powder coated surfaces
  • Plastics
  • Anodized aluminium
  • Painted surfaces
  • ...


  • Contains solvent (not water)
  • Clear, colourless liquid based on silanes
  • Ultra high performance, hardness of 7-9H
  • High impact strength
  • Is ideally suited for the water/dirt-repellent coating of non-absorbent materials in outdoor and indoor areas
  • Can be sprayed or wiped on to surfaces
  • Generates a generally invisible surface. The coating does provide a glossy appearance
  • Extremely resistant to corrosion, alkali, abrasion, sea water and salty air (extensive Salt spray testing has been conducted. In addition testing shows that this coating is also resistance to rocket fuel!)
  • Highly resistant to a large number of organic solvents
  • Treated surfaces remain clean for prolonged periods and are “easy to clean”
  • Protected surfaces provide reduced costs for cleaning and care
  • Food safe
  • Heat resistant up to 700-750°C working temperatures
  • Cold resistant up to -90°C
  • Highly effective for up to 25 years
  • Heat drying increates the hardness of the coating, which ranges from 7H (for room temperature curing) to 9H (for heat curing)
  • Contains no alkaline metals or boron
