TEKNOSILOX STRUCTURE 3352
High-solid polysiloxane paint
- Chemical resistant
- Corrosion protective
- 2-component
- Solvent-borne
- Topcoat
TEKNOSILOX STRUCTURE 3352 is a low-solvent polysiloxane coating.
TEKNOSILOX STRUCTURE 3352 is mainly used as a topcoat for primered steel constructions, tanks and bridges, where a long durability time of the coating system is required.
Excellent weather-fastness, structured/textured surface easy achievable by using common applications techniques Results in a surface which is resistant against acids, chemical spills and splashes, humidity and moisture. Outstanding corrosion resistance, high abrasion resistance.
Surface preparation
Remove from the surface any contaminants that might be detrimental to surface preparation and coating. Remove also water-soluable salts by using appropriate methods. The surface should be prepared as follows: STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation grade Sa 2½ (standard ISO 8501-1). Roughening the surface of thin-plate improves the adhesion of the paint to the substrate. ZINC SURFACES: Hot-dip-galvanized steel structures that are exposed to atmospheric corrosion can be painted if the surfaces are sweep blast-cleaned (SaS) till matt all over. Suitable cleaning agents are, e.g. aluminium oxide and natural sand. It is not recommended to paint galvanized objects that are subjected to immersion strain. It is recommended that new zinc-coated thin-plate structures are treated with sweep blast-cleaning (SaS). ALUMINIUM SURFACES: Surfaces that are exposed to weathering are also roughened up with sweep blast-cleaning (AlSaS) or sanding. OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Any impurities that might be detrimental to the application of paint (e.g. grease and salts) are to be removed. The surface must be dry and clean. Old, painted surfaces that have exceeded the maximum overcoating time are to be roughend as well. Damaged parts are prepared in accordance with the requirements of the substrate and the maintenance coating. Time and place of preparation should be so chosen, that the prepared surface will not get dirty or damp before further surface treatment.
