In addition, the amount of pigments and fillers also has a certain impact on the degree of temperature resistance. When the relevance is met, the resin is generally added with appropriate organic Silicone to solve the problem. The temperature range between 270 and 350 °C is a more sensitive range point for silicone high temperature resistant powder coatings. At present, silicone resins used in high temperature resistant powder coatings are mainly divided into the following two types: Methyl polysiloxane is characterized by: good hardness; good water repellency; low surface energy and non-stick effect;-good yellowing resistance at high temperatures; but poor miscibility with other organic resins.

The optimal dosage range is determined to be between furniture powder coatings Factory 60% and 100% (compared to the resin problem). At present, heat-resistant powder coatings are still dominated by organic silicon powder coatings. Silicone resin can be used as a base material alone or combined with polyester and epoxy resin to improve the high temperature resistance of the coating film. Phenyl polysiloxane, good miscibility; good flexibility; good gloss and color retention.

Silicone resin is an indispensable base material for high temperature resistant powder coatings. However, if the silicone resin is used alone, the intermolecular force is relatively small, the adhesion is poor, and the price is relatively high.

High temperature resistant powder coatings are mainly composed of high temperature resistant resins, high temperature resistant pigments, high temperature resistant fillers and special effect additives; due to high temperature resistance, they are widely used in chemical, petroleum, metallurgical, aviation and other industries. Of course, the actual dosage of different silicone resins needs to be determined experimentally.

In addition, due to the agglomeration of low Tg silicone resins during storage, production and transportation, the development of high Tg (glass transition temperature) silicone resins has become inevitable. Good hot and cold alternation. We know that silicone resins are mainly based on silicon-oxygen bonds.3, the heat resistance time of the coating film rises from about 50h to 100h.
