The chemical structures of silicone resins and silicone hybrid resins result in remarkable property profiles that cannot be achieved by other classes of resins. These binders are used as the main constituent in many industrial applications, ranging from weather- and chemical-resistant coatings for building conservation to high-temperature-resistant paints.
Silicone resins are used primarily in the latter application due to their higher silicone content and their ability to withstand high temperatures better than silicone hybrid resins. High-temperature-resistant coatings – used for exhaust systems, industrial ovens, grills and combustion chambers – must retain corrosion protection and weather resistance properties, and satisfy very high demands on thermal stability. Such coatings are normally used on steel at dry film thicknesses of 20-25 µm.
