Physical Properties

Application

• SiSiB® SR5660 is particularly suitable for a wide range of heat-resistant coatings. It is ideal for (corrosion protection) coatings for fireplaces, mufflers, exhaust systems, engine components, boilers, furnaces, ovens and oven linings, chimneys, barbecues, electric/gas heaters, incinerators, etc.

• Heat-resistant coating formulations using SiSiB® SR5660 in combination with suitable heat-resistant pigments and fillers can achieve thermal stability up to 500°C. Aluminium pigments can be used for silver/grey coatings and black pigments such as iron manganese oxide or copper chrome black spinel for deep black coatings. Platelet-shaped inorganic fillers/extenders such as mica or talc are suitable for such formulations. Pigments and fillers must be well dispersed in the coating.

• Degreasing/cleaning and sandblasting of the substrate are recommended to achieve the best corrosion resistance and thermal stability of the metal surface. Adhesion also always depends on the specific coating formulation. Coating application can be carried out by spraying, dipping and brushing.

• Coatings made with SiSiB® SR5660 dry at room temperature to form a non-stick film and already provide temporary corrosion protection. Baking at 180°C for 2 hours effectively reduces the risk of cracking at extreme temperatures.

• SiSiB® SR5660 can be combined with organic resins such as alkyd, acrylic, polyester, and epoxy to develop a variety of temperature-resistant coatings for different applications.
