Silicone resins are widely applied as coating materials due to their unique properties, especially those related to very good heat resistance. The most important effect on the long-term heat resistance of the coating is connected with the type of resin. Moreover, this structure is stabilized by a chemical reaction between the hydroxyl groups from the organoclay and the silicone resin. The novel trends in application of silicone resins in intumescent paints used mostly for protection of steel structures against fire will be presented based on literature review. Some examples of innovative applications for fire protection of other materials will be also presented. The effect of silicone resin structure and the type of filler used in these paints on the properties of the char formed during the thermal decomposition of the intumescent paint will be discussed in detail. The most frequently used additives are expanded graphite and organoclay. It has been demonstrated that silicate platelets are intercalated in the silicone matrix, significantly increasing its mechanical strength and resulting in high protection against fire.
由于其独特的性能，特别是与非常好的耐热性相关的性能，有机硅树脂被广泛用作涂料材料。对涂层长期耐热性最重要的影响与树脂类型有关。此外，这种结构通过有机粘土中的羟基与有机硅树脂之间的化学反应得以稳定。基于文献综述，将介绍有机硅树脂在主要用于保护钢结构防火的膨胀型涂料中的新型应用趋势。还将介绍一些用于其他材料防火的创新应用实例。将详细讨论有机硅树脂结构和这些涂料中使用的填料类型对膨胀型涂料热分解过程中形成的炭的性能的影响。最常用的添加剂是膨胀石墨和有机粘土。已经证明，硅酸盐薄片插入有机硅基体中，显著提高了其机械强度并带来了高防火性能。
