The coatings used outdoors (i.e. weather resistant coatings) need to withstand wind, sun, rain, alternating cold and heat, ultraviolet radiation, etc. Due to the absence of unsaturated bonds in the molecules of silicone resin, it has excellent resistance to atmospheric corrosion. UV radiation does not easily cause it to crack or crosslink, and long-term exposure to outdoor sunlight results in no loss of gloss, powdering, discoloration, or intact paint film. Its weather resistance is excellent.Fo ...

In addition to heat resistance, silicone coatings also have characteristics such as weather resistance, water resistance, resistance to various gases and vapors, resistance to ozone and ultraviolet degradation. Therefore, it has been widely used as a heat-resistant and anti-corrosion coating for flue gas, boilers, electric furnaces, various heaters, cement roasting furnaces, petroleum cracking furnaces, and as an insulation protection coating for aircraft, missiles, spacecraft, etc. It can work ...

The method of cold mixing is mechanical mixing, which requires a higher phenyl content of organosilicon. It can produce a certain degree of condensation reaction during baking, heating or use to form a more uniform paint film. If the phenyl monomer contains a large amount of organosilicon monomer, it can be cold mixed with phenolic cheese, amino, alcohol acid, epoxy, polyester and other resins, resulting in modified organosilicon resin with improved adhesion and mechanical strength, and lower pr ...

Pure organic silicon heat-resistant coatingPure silicone resin varnish can only withstand high temperatures of 250-600℃ and remain intact for a considerable period of time at this temperature. At a temperature of 550℃, the silicone resin gradually evaporates.Organic silicon zinc powder paint and aluminum powder paintOrganic silicon zinc powder paint can withstand 400℃.for a long time and has anti-corrosion effect on steel when used as a primer.To prevent the generation of hydrogen gas during ...

The formula for silicone heat-resistant coatings is mainly based on the selection of silicone resin and pigment fillers according to different usage conditions. Heat resistant coatings that are only affected by high temperatures are generally formulated with pure silicone resin to have high heat resistance. High temperature coatings that require oil resistance and wear resistance, such as heat-resistant coatings for aviation, often use epoxy modified silicone resin. Heat resistant coatings that ...

When preparing organic silicon high-temperature resistant coatings, fillers (such as mica powder, talc powder, calcium carbonate, etc.), pigments (such as aluminum powder, zinc powder, carbon black, etc.), and catalysts (such as octanoates or cyclic carbonates of zinc, diamond, magnesium, iron, etc.) should be added to the silicone resin. The types of pigments and fillers have a significant impact on the heat resistance of the formulated coatings. Pigments and fillers used in heat-resistant coat ...

Due to the extensive application of polymer materials such as plastics and synthetic fibers, the flammability and flammability of these materials pose a threat to human life and property safety, which has made flame retardants one of the key focuses of safety and fire prevention research. By introducing the combustion of polymers, various types of flame retardants, and their flame retardant mechanisms, organic silicon flame retardants not only endow substrates with excellent flame retardant prop ...

Introduction to flame retardantsOrganic silicon flame retardant: The molecule contains siloxane chain segments, which can increase the oxygen index of the material. After combustion, the amount of carbon formed in the system will also increase, effectively reducing the heat release of the material. Mainly including organosiloxane, polysiloxane, siloxane copolymer, polysilicborane, and silicone resin. This series is halogen-free, efficient, low smoke, and eco-friendly, making it an important dire ...

Silicone resin has excellent properties such as heat resistance, cold resistance, moisture resistance, hydrophobicity, and weather resistance. It can be used as a special coating (i.e. silicone coating) and plays a significant role in the special coating industry. There are many types of organic silicon coatings, mainly including high-temperature resistant coatings, weather resistant coatings, wear-resistant hardening coatings, anti adhesive release coatings, moisture-proof and hydrophobic coati ...
