SCS AdPro Poly® was engineered to solve the adhesion challenges of many polymeric materials, including polyimide substrates, enabling parylene coatings to provide long-term reliability and protection for innovative, complex technologies. In the electronics, medical device, automotive, and military/aerospace industries, various thin-film coatings are used for surface modification, protection enhancement, and biostability to enhance the overall reliability of polymeric devices.

“One problematic aspect of using polymeric substrates relates to adhesion of such coatings to the devices’ surfaces,” said Rakesh Kumar, Ph.D., vice president, Technology. “Factors such as surface contamination, presence of oxide layers, and low surface energy substrates can lead to poor adhesion and the reduction in the effectiveness of coatings used in these devices.”

According to the company, AdPro Poly can enhance the adhesion of parylene coatings with polyimide and other polymeric substrates to a level not previously possible. The material has also reportedly demonstrated improved stability at elevated temperatures, making it a suitable adhesion promotion system for harsh environment applications. It is also biocompatible for medical device applications.
