TEKNOHEAT 1178 is a one-component, solvent-borne topcoat based on a combination of silicone resin and other binders.
It provides excellent adhesion and is intended for use as a topcoat over TEKNOHEAT PRIMER 1174 in high-temperature coating systems. In combination with TEKNOHEAT PRIMER 1174, the topcoat offers thermal resistance with short-term exposure up to 500 °C.
Technical data sheet
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 surfaces are prepared according to the different materials as follows:
OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Any impurities that might be detrimental to the application of paint (e.g. grease and salts) are removed. The surfaces must be dry and clean. Old, painted surfaces that have exceeded the maximum overcoating time are to be roughened as well.
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.
Suitable airless nozzle size 0.009 - 0.013"
Application conditions
The surface to be treated must be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +5°C and the relative air humidity below 80%. Additionally, the temperature of the surface to be treated and the product must be at least +3°C above the dew point of the ambient air.
Storage
The storage stability is shown on the label. Store in a cool place and in tightly closed containers.
