Silicone resin is a more common kind of resin. The unique characteristics of silicone resin are welcomed by everyone. So what is the difference between the performance of silicone resin and ordinary resin? Follow this article to find out.
1.High temperature resistance
Generally, the heat-resistant temperature of synthetic resin paint is below 150 ℃, while the silicone paint can be used for a long time at 200 ℃. If high-temperature pigments are added, the heat resistance can reach 400 ° C to 500 ° C, and special ones can also reach 800 ° C to 900 ° C. Therefore, it is suitable for coating high temperature resistant parts.
2.Electrical performance and hydrophobicity
Because the outer layer of the silicone paint has a layer of non-polar organic genes and molecular symmetry, it has become the basic reason for its good electrical insulation properties and hydrophobicity. In terms of insulation, it not only has high insulation resistance, but also shows excellent performance in terms of breakdown amplitude and high-voltage arc spark resistance. Therefore, it can be used to impregnate motors and parts with high insulation performance requirements to improve the insulation components. Insulation class.
3.High surface activity and low tension
Since polysiloxane is a symmetric molecule and the substituent is a non-polar organic group, the entire molecular formula is non-polar. The inter-molecular force is small, and the cohesion of the molecule itself is also small, so the surface tension is small. When it is dispersed on the surface of a medium with a large surface tension, it can separate the medium, and because the interaction between the molecule itself and the medium is also small Therefore, it can reduce the surface tension of the medium, making it difficult to form foam. This is the reason why silicone oil can be used in paint to defoam. Therefore, it can be used as a defoamer and leveling agent in paint to prevent paint film from emitting light and pitting.
Resin usually refers to a range of softening or melting after heating. When softening, it has a tendency to flow under the action of external forces. It is solid, semi-solid at normal temperature, and sometimes it can be a liquid organic polymer. Broadly speaking, any polymer compound that can be used as a raw material for processing plastic products is called a resin.
Relative molecular weight is uncertain but usually high. It is solid, medium solid, pseudo-solid at normal temperature, and sometimes liquid organic matter. It has a softening or melting temperature range, has a tendency to flow under external forces, and often breaks into a shell shape when broken. Broadly, it refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents. According to the source, it can be divided into natural resin and synthetic resin; according to the different characteristics of its processing behavior, there are thermoplastic resin and thermosetting resin.
