643 Metal Dura Easy On - Metal Coating

643 Dura Easy On Metal Coating is the newest generation of ceramic coatings. This coating off ers high water and dirt repellency linked with high durability against mechanical wear on synthetic or metallic surfaces. Inorganic groups give 643 Dura Easy On perfect adhesion to the substrate and a pencil hardness of 9H. This coating can be multi layered.

ALGT© Use Cases


  • Graffiti protection
  • Strong dirt and water repellency
  • Corrosion inhibiting characteristics


  • Graffi ti protection (e.g. road signs)
  • Strong dirt repellency (e.g. truck tarpaulin)

Clean the surface thoroughly with a residue-free cleaner. For carpaints, we recommend butyl acetate. When applying manually it is suggested that a gentle circling motion is utilized in order to ensure that no visible surplus is evident, (if required, this process be repeated up to 3 times, at intervals of 5-10 minutes in order to increase the layer thickness.) The coating becomes water-resistant after 24 hours and becomes fully cured against mechanical abrasion and chemical within 7 days. The drying time and hardness of the coating can be enhanced by the application of heat, eg apply 80°C of heat for 30 minutes to the coated item, then allow the item to cool for 3 hours, after which the coating will be fully cured.
