Pre coated coil coatings are economically and environmentally friendly, meeting the needs of today's social and economic development, and therefore are becoming increasingly widely used. With the continuous advancement of technology, its application fields have expanded to home appliances, decoration, furniture, etc., but its main use is still in the construction industry, with a large amount of external rolls requiring long-lasting aesthetic decoration and protective performance. Organic silico ...

The coating performance of modified polyester powder coating: The silicon containing polyester in organosilicon modified polyester is enriched on the surface, forming a protective layer containing astatine, greatly reducing the surface tension of polyester resin, thereby bringing some excellent characteristics of organosilicon resin and improving the weather resistance and water resistance of its powder coating.Compared to pure polyester resin, a 1% organic silicon mass fraction can reduce the s ...

Introducing silicone resin with UV resistance and strong hydrophobicity into the structure of alkyd resin greatly improves the gloss retention, powdering resistance, color retention, and weather resistance of the alkyd resin coating, enhancing its outdoor value. Can be used as a durable coating for outdoor steel structural components and appliances. Self drying modified alkyd resin is commonly used as a maintenance coating, suitable for permanent buildings and equipment, such as iron towers for ...

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 ...
