For more than 40 years, Paratronix has advanced the science of conformal coatings. As a division of Kayaku Advanced Materials, we unite process engineering and polymer chemistry to deliver reliable protection for critical technologies worldwide.
Our Story
Founded in 1981, Paratronix began as one of North America’s first providers of commercial Parylene coating services.
Through decades of continuous improvement and process innovation, we’ve earned a reputation for precision, reliability, and responsive engineering support.
Joining Kayaku Advanced Materials expanded that capability, linking our coating expertise with world-class material development and global manufacturing resources.
Our Role Within Kayaku
Paratronix operates as Kayaku’s dedicated coating services arm, translating material science into applied performance.
By combining deep R&D knowledge with precision coating processes, Paratronix enables reliable, application-ready solutions.
For customers, this means:
What We Deliver
