EL SEGUNDO, Calif.—A high-temperature phthalonitrile coating introduced by Cambium is engineered for metallic and composite substrates operating in extreme thermal environments, the company said in a release.
The new ApexShield 3000 coating is reported to support applications from hypersonic flight to electromagnetic interference (EMI) and radio frequency (RF) shielding for electronics and commercial programs requiring wavelength-tunable performance. It accepts conductive and non-conductive fillers, enabling engineers to customize performance characteristics for specific program requirements, according to Cambium.

“ApexShield 3000 is a sprayable, solvent-based 1-part liquid that cures at temperatures as low as 215°C (419°F) and delivers sustained operational performance up to 315°C (600°F), with short-duration capability up to 427°C (800°F),” the release stated. “The system requires no refrigerated storage and is available in quarts, gallons, and drums, supporting both prototype development and production-scale programs.” A technical data sheet is available at cambiumglobal.com.
Cambium is a developer of advanced materials for high-performance applications. According to the company, its differentiation is not any single class of advanced materials but a unique development approach. Its approach is said to offer customers “every aspect of molecular discovery, product development, certification and qualification, and rapid scalable manufacturing across the U.S. and Europe, all under one roof.”
“ApexShield 3000 gives engineers a practical, high-performance solution for protecting structures that operate in environments where standard coatings fail,” said Cambium CTO James Griffin, in the release. “The combination of sprayable application, room-temperature storage, and validated high-temperature performance makes this a deployable tool for defense and aerospace manufacturers working under real production constraints.”

ApexShield 3000 builds on Cambium’s growing portfolio of phthalonitrile-based materials, including the ApexShield 1000 resin system. ApexShield 1000 reportedly reduced carbon-carbon parts fabrication cycles by 70 to 80 percent for hypersonic applications.
Cambium is working to redefine how advanced materials are discovered, designed, and manufactured. Its development of advanced materials for high-performance applications across land, air, sea, and space is said to leverage molecular innovation that combines AI-driven molecular design with state-of-the-art chemistry, materials science, and biology.
“The company delivers exceptional speed from concept to production and qualification,” the release stated. “Manufacturing is carried out through a secure, flexible, and scalable domestic supply chain, enabling defense and commercial innovators to move from prototype to full-scale production fast.”
