Siloen® SR 833 is a 100% active methyl alkoxy silicone resin. However, it can be diluted with various solvents (e.g., aromatics, esters, and ketones). As a binder in silicone resin coatings, Siloen® SR 833 can withstand temperatures of up to 600 °C, making it the basis for high-temperature coatings.

High-temperature coatings are used in a wide variety of areas, e.g., for the exterior coating of frying pans, wood-burning stoves, or exhaust systems in motor vehicles. It is important that the pigments and fillers used are also suitable for the temperature range. Aluminum pigments offer the highest heat resistance, while black iron oxide pigment remains stable up to approx. 500 °C. If good corrosion protection is also required, zinc dust can also be used.

Cross-linking occurs with air humidity through polycondensation and is initiated by catalysts, e.g., titanium tetrabutoate. The reaction itself only requires room temperature, which makes processing easy, and is completed after a few minutes. The catalyst should therefore only be added shortly before use. When used as a 1K coating, care must be taken to ensure that it is free of water. The recommended dry film thickness is a maximum of 25 μm, resulting in a coating with very low smoke and odor development but high hardness.

Disperse positions 1-5 in the bead mill to the desired grain fineness. Add positions 6-8 while stirring. Protect from moisture during production; use as a 2K coating if necessary. If a 2K coating is to be produced, increase the proportion accordingly.

Our Italian supplier partner Vinavil is committed to improving sustainability through numerous environmental, social, and economic initiatives. Vinavil's research and development department is increasingly focusing on sustainable and bio-based products by minimizing the use of hazardous substances, making production processes more efficient, recycling waste materials, and introducing new raw materials from renewable sources.

The availability of bio-based monomers as an alternative to fossil-based materials is probably the most important and biggest challenge for all polymer manufacturers who are striving to achieve a high proportion of renewable raw materials. CRILAT BIO D117 AF is Vinavil's first polymer dispersion made from bio-based raw materials. The pure acrylate dispersion has a bio-based raw material content of 29%. CRILAT BIO D117 AF is also free of solvents, ammonia, and formaldehyde.

CRILAT BIO D117 AF is used particularly in decorative interior paints due to its good rheological behavior. Thanks to its alkali resistance and strong color fastness, it gives formulations good weather resistance. All these properties make CRILAT BIO D117 AF a very versatile polymer dispersion for formulating sustainable interior and exterior paints.
