TEKNOTHERM 4400 is a high-solid polyester baking varnish with good adhesion to steel, aluminium and galvanized substrates. It forms a resilient surface which is resistant to water, oil, weak bases and acids.

Used as a good one-coat finish for steel and non-ferrous metals. Good adhesion to steel, aluminium and zinc surfaces. Provides a good scratch and impact resistance combined with a good flexibility. Resistant to water, oil, weak acids and bases. Good weather resistance.

Surface preparation

Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods. The surface should be pretreated as follows: Oxilane ®, ironphosphate or zincphospate. The place and time of the preparation are to be chosen so that the prepared surface will not get dirty or damp before the subsequent treatment. Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.

Application

Stir thoroughly before use. Recommended application method: ESTA high speed rotating disk or pneumatic high pressure spray gun.

Application conditions

The surface to be treated must be dry and the relative air humidity below 80%. During the application and drying period the temperature of the ambient air and the surface shall be at least above +10°C and the temperature of the paint must be at least 3°C above the dew point of the ambient air.
