1. Corrosion resistance
The world's annual loss of steel due to rust accounts for about 1/4 of the world's annual production of steel, outdoor street lights and car parts have been far from the ship, our life everywhere need to prevent corrosion. So silicone became our best choice.
2. Thermal stability
Silicone resin heat resistance is far better than ordinary organic resin, ordinary silicone resin temperature up to 300℃, if the use of phenyl silicone resin, with technology, silicone coating can withstand 600 degrees of high temperature, such as IOTA 1056D. Organic silicon can not only high temperature resistance, and resistant to low temperature, and its chemical properties and physical properties with temperature change is very small, that is easily with organic silicon molecules around the curve of spiral structure, when the temperature rises, on the one hand, increases the average distance between molecules, on the other hand spiral extension to reduce the distance between the molecules, stretching and contraction of the spiral can alleviate the effects of temperature, Thus it has excellent temperature resistance.
3, weather resistance
Weather resistance is one of the main characteristics of silicone resin, so it is widely used as a film forming polymer for high weather resistance coatings. Weatherability is simply the ability to adapt to natural outdoor environments. Uv resistance, sun resistance, etc
There are two reasons for good weather resistance of silicone resin: one is that si-O bond in silicone resin is very stable, it is difficult to produce free radical reaction caused by ultraviolet light, and it is not easy to oxidation reaction; The other is that silicone is not sensitive to sunlight. Methyl siloxane almost does not absorb ultraviolet light, so the impact of sunlight on silicone resin is small, which is the main reason for the good weather resistance of silicone resin coating.
4, water resistance
In the molecular structure of silicone resin, its organic groups such as methyl and other outward arrangement, and does not contain polar groups, so silicone resin water absorption is low, with excellent hydrophobicity. (We also have hydrophilic nanocoatings.)
5, electrical insulation
The electrical properties of silicone paint film are similar to those of organic resin with excellent electrical properties under normal conditions, but the electrical properties of silicone paint film are much better than those of organic resin under high temperature and humidity conditions. It maintains excellent electrical insulation performance over a wide range of temperatures and frequencies, and due to its high heat resistance, the electrical characteristics of silicone at high temperatures are rarely reduced, and the high frequency characteristics vary very little with frequency. Although the resistivity of silicone also decreases as the temperature increases, it does so much more slowly than that of organic resins.
