Surface preparation

The maximum performance of Tectyl 120 can be achieved only when the metal surfaces to be protected are clean, dry and free of rust, oil and mill scale. Valvoline recommends a substrate temperature of 10-35 °C at the time of product application. Avoid direct contact of the product with PVC due to possible material incompatibility


Tectyl 120 is formulated to be used as supplied. It is recommended that the ambient and product temperature be 10-35 °C at the time of product application. Tectyl 120 can be applied by airless spray or brush. Details on application can be found in the application chart.


Tectyl 120 can in the wet phase be removed with Tectyl Biocleaner or Valvoline 150 or low-pressure steam. If dried and cured the film of Tectyl 120 can also be removed with Valvoline 150.
