Technology from Outter Space to Earth: Silicones as Protective Coatings

Compared to other polymeric materials, silicone offers greater performance in harsh environments. Inherently silicone possesses a large coefficient of thermal expansion (CTE), low modulus, and a low glass transition temperate (Tg). These attributes allow it to maintain elastomeric properties for continuous operation when exposed to extreme heat, cold, and/or UV radiation. Durability is the reason silicone materials are frequently employed as coatings and sealants.

Compared to other polymeric materials, silicone offers greater performance in harsh environments. Inherently silicone possesses a large coefficient of thermal expansion (CTE), low modulus, and a low glass transition temperate (Tg). These attributes allow it to maintain elastomeric properties for continuous operation when exposed to extreme heat, cold, and/or UV radiation. Durability is the reason silicone materials are frequently employed as coatings and sealants. In electronic equipment, silicone coatings protect device functionality amidst temperature fluctuations during use. On the exteriors of ships, aircraft, etc., they protect vehicles from wear and tear otherwise brought on by the elements. Beyond these summations, silicone coatings can be designed to provide more customized protection according to specific needs. For example, electrical or thermal conductivity comes from the incorporation of certain functional fillers, and permeability to moisture and gases is adjusted through silicone polymer alteration. With or without adjustments such as these, silicone consistently affirms its efficacy, even in the vacuum of outer space. Silicone coatings are protective because they are resilient and adaptive, able to provide fortification for long-term reliability of material systems subject to extreme conditions.
