Over the last 50 years, the aerospace and aircraft industries have used silicone in an ever-growing number of applications. Silicone inherently has high dielectric strength (typically ≥ 500 V/mil) and a large coefficient of thermal expansion (CTE), allowing it to absorb stresses during thermal cycling.

Adhesive bonding can be used to assemble identical materials or materials of different types; the purpose of such an assembly is to transfer mechanical loads in a given environment.

Industries ranging from automotive and consumer electronics to building and construction are designing and manufacturing products that call for increasingly sophisticated bonding solutions.

Suppliers, customers and channel players in China’s silicone sealant industry agree that the best products come from foreign brands. They also agree that customers are demanding higher and higher quality sealant products.
