Silicones (Si)

Silicone adhesives appear as clear to translucent materials with exceptional flexibility and elasticity. Key features include remarkable temperature resistance, durability, excellent electrical insulation properties, and UV stability. Silicone adhesives are used in electronics assembly, construction sealing, and aerospace applications where extreme conditions would compromise conventional adhesives. 

Market developments include increasing focus on fast-curing formulations, hybrid silicones, and specialized grades for enhanced thermal conductivity, electrical conductivity, or flame retardancy. Sub-types include condensation-cure silicones that release byproducts during curing, addition-cure systems offering no byproduct formation, and pressure-sensitive silicone adhesives with permanent tack.
