Hostagrund K2100 Silicone Silver Paint for Metal up to 500 °C, silver, 350 g

HOSTAGRUND® SILICONE SILVER is suitable for protecting, for example, heat exchangers, flue pipes, furnace doors, automotive exhausts made of stainless steel, steel pipes for hot steam, dryer exhausts, etc. The paint is applied on a dry, degreased surface with a brush or by spraying in one to two layers, depending on the aggressiveness of
the surrounding environment. For better protection of the metal against corrosion, it is advisable to apply the paint on a fired coating made from the coating material HOSTAGRUND® SILICONE PRIMER. The paint is not intended for applications that come into direct contact with food, animal feeds, and drinking water.

Preparation of the substrate:
The substrate for application must be clean, dry, free of grease, rust, and dust, and mechanically cleaned. First of all, the surface must be degreased using a suitable cleaning agent (e.g., technical petrol P 6402, acetone P 6401, or where possible, warm pressurized water containing detergent). To remove any residue of various salts, the surface
must subsequently be rinsed with clean water. Coarse and well-adhering impurities must be removed manually or mechanically (sanding, scraping). Any loose rust can also be removed manually or mechanically (metal brushes, sanding discs). The ideal preparation of steel and cast iron substrates is blasting to class Sa 2 ½ according to CSN EN ISO 8501-1
Previously painted surfaces must be cleaned, degreased, and stripped of old non-adhering coatings. To ensure compatibility of the new coating with the old one, it is recommended to perform a test reference coating.

It is recommended to comply with the entire coating system according to the manufacturer’s technical data sheet. An imperfectly prepared surface may cause problems with the adhesion of the coating material to the substrate or even with the adhesion between individual layers. Furthermore, it may negatively affect the overall appearance of the coating film.

Example of the coating procedure:
Before use, the paint is stirred and, if necessary, thinned with the recommended thinner. The paint is applied to the pre-prepared substrate. To ensure better protection against corrosion, it is advisable to coat the substrate with the primer HOSTAGRUND® SILICONE PRIMER. In the base coating, allow the solvents to drain for about 30 minutes and then bake the coating at 200°C for 2 hours. After cooling the primer, apply HOSTAGRUND® SILICONE SILVER. After draining the solvents for about 30 minutes, the coating is baked at a temperature of 200°C for 1 hour. If additional layers are applied, each layer of the coating system must be baked separately. When subsequently
baking, ensure a gradual increase in temperature !! HOSTAGRUND® SILICONE SILVER can also be used without baking, but it is softer and does not withstand the action of organic solvents.
