Problems solved by technology

Organic high-temperature-resistant coatings include heterocyclic polymer coatings and elemental organic polymer coatings, etc. Among them, silicone high-temperature-resistant coatings have good temperature resistance and the largest variety of high-temperature-resistant coatings, and play a pivotal role in high-temperature-resistant coatings , but there are generally poor drying properties at room temperature and low high temperature resistance limit, which limits its promotion and application to a certain extent.

[0003] Silicone resin has the characteristics of thermal oxidation stability, high temperature resistance, and ultraviolet radiation resistance. It is the preferred resin material for thermal protective coatings, but it also has shortcomings, such as poor mechanical strength, adhesion, and chemical resistance. It requires high temperature baking and curing. In order to overcome these shortcomings, it needs to be modified with organic resin to make it have more comprehensive properties and obtain wider applications.
