Silicone adhesives and coatings can extend the life of vehicles, ships and aircraft. The outer shell is more resistant to rain, wind, salt, friction, UV radiation, and chemicals such as gasoline. Joints last longer and overall maintenance and repair costs are lower. Silicones can be used to connect most parts of automobiles, ensuring that components and systems are intact, airtight, and resistant to various environmental stresses and pressures that may affect performance. The interiors of most cars (as well as ships and aircraft) are assembled using silicone-reinforced adhesives that offer bonding strength comparable to that of welding or riveting but significantly reduce the expense of time, labor and materials. Such adhesives reduce weight—an important feature for aerospace applications. The use of sealants containing silicones can keep traffic lights and their underground sensors dry and functioning well, and the use of certain silicones can reduce volatile organic compound (VOC) emissions, benefiting the industry and the public.
