We know silicones from lots of applications in engineering and daily life. Silicones also have very specific properties. In here, we will explain the general properties of thermoset silicones adn some of applications of them. Also you can find information about thermoset silicon resins here.
Silicones can be semi-organic and inorganic according to the presence of siloxane links which have chemical representation of –Si–O–. In general silicones, CH3 and SiO are combined to obtain various proportions. According to this variation, they can be produced as thermosets, elastomers and fluids.
Silicones’ heat resistance and water resistant properties are very important for such applications. But mechanical properties of silicones such as strength is not good as other cross-linked thermosettings.
As you understand that thermosetting silicones has cross-linked molecular structure. With this highly cross linked structure, they are used in these kinds of applications; varnishing, painting and other coating applications for circuit boards. Curing is achieved by heating the silicones.
The production method of general thermoset silicones is step polymerization. They are highly brittle materials which has elongation according to original shape is 0. Tensile strength is generally 30 MPa.
Thermosetting silicones does not have very big market in polymer industry. So general properties and applications of thermosetting silicone resins can be summarized as above.
