"Silicone" generally refers to an organic silicon polymer material that has a skeleton formed by the bonding of silicon and oxygen (siloxane bond / -Si-O-Si-) with organic groups (methyl groups) attached to the side chains of silicon atoms. It is chemically inert, has a small change in viscosity with temperature, and is characterized by low surface tension. Compared to the C-C bonds of typical organic compounds, the Si-O bond energy is higher, and the internal rotational energy is nearly 0 KJ/mol, making the rotation of the main chain bonds easy. It possesses properties such as flexibility, heat resistance, cold resistance, low surface tension, and gas permeability. Organic silicon resins, polyorganosiloxanes, and polysiloxanes may also be collectively referred to. [Properties] ■ Flexibility ■ Heat resistance ■ Cold resistance ■ Self-extinguishing ■ Low toxicity ■ Electrical insulation ■ Low surface tension ■ Weather resistance ■ Gas permeability *For more details, please feel free to contact us.

"Leveling property" refers to the smoothness of the paint film achieved through the flow of the paint before the film is formed, which is not affected by the unevenness of the substrate or the primer, and helps suppress defects in the paint film such as beading and dents. Additionally, "wetting property" is the characteristic of paints and inks that allows them to be applied to the substrate without gaps or beading. Generally, a lower surface tension (surface energy) results in higher effectiveness and correlates with higher fluidity (flowability). *For more details, please refer to the related links or feel free to contact us.*
