Surface preparation

The maximum performance of Tectyl 506-EH can be achieved only when the metal surfaces to be protected are clean, dry and free of rust, oil and mill scale and a substrate temperature of 10-35 °C at the time of product application.


Tectyl 506-EH is formulated to be used as supplied. Due to its composition Tectyl 506-EH can be subject to postproduction viscosity changes and/or wax sedimentation. Always ensure homogeneous consistency by agitation before use. If the product thickens due to cold storage or loss of solvent during use, thinning with Valvoline 150 is possible to get the desired consistency. Incorrect thinning will affect film build, dry time and potentially product performance. Tectyl 506-EH can be applied by low pressure air spray or brush. Details on application can be found in the application chart.


Tectyl 506-EH can in the wet phase be removed with Tectyl Biocleaner, Valvoline 150 or lowpressure steam. If dried and cured the film of Tectyl 506-EH can also be removed with Tectyl Biocleaner or Valvoline 150
