TEKNOHEAT 500
Silicone paint
- Heat resistant
- 1-component
- Solvent-borne
- Topcoat
TEKNOHEAT 500 is a silicone paint that withstands high temperatures.
Used as a top coat in zinc silicate/silicone systems on hot surfaces indoors and outdoors, e.g. flues, stoves, oven doors and exhaust pipes. Steel surfaces that are temporarily damp must be primed with appropriate anticorrosive zinc dust paints. The paint forms a film that withstands permanent heat up to +200°C - +400°C depending on the colour (see section Colours). Colours which are used in +400°C can momentary withstand heat up to +500°C. Aluminium colour (RAL-9006) withstands heat up to +650°C.
Surface preparation
THIN-PLATE SURFACES: Brush corroded areas carefully and remove all grease and dirt by washing the surfaces e.g. with RENSA STEEL washing agent for galvanized surfaces.
STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation grade Sa 2½ (standard ISO 8501-1).
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.
Prefabrication primer: KORRO SS zinc silicate prefabrication primer can be used, when required.
Application
Stir thoroughly before use. Suitable airless nozzle size 0.013 - 0.017"
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%. The temperature of the surface to be painted must not be above +50°C. 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
Must be stored tightly closed and kept cool and dry.
