Revolutionizing Aerospace Maintenance: PPG's 3D Printed Sealant Technology
For over 70 years, PPG has established itself as a leader in innovation within the aerospace sector, providing cutting-edge solutions that enhance safety, efficiency and performance. From sealants to advanced transparencies and coatings, PPG has consistently pushed the boundaries of technology. The latest breakthrough from PPG’s aerospace business is the introduction of its proprietary 3D printed sealant technology, a game-changer that promises to redefine the standards of aircraft manufacturing and maintenance.
The Evolution of Sealant Applications
Historically, the application of sealants in the aerospace industry has relied on two-part systems that require mixing and manual application. Renowned PPG product names such as PRO-SEAL™ and PRC-DESOTO® brand sealants have been staples in the maintenance world, but the traditional methods often come with challenges. Hand application is heavily dependent on the skill level of the technician, which can sometimes result in a messy and imprecise application.
PPG ARE™ 3D printed sealants address these issues head-on. By leveraging advanced additive manufacturing techniques, PPG has developed a solution that not only simplifies the application process but also enhances the quality and reliability of sealant applications.
Key Features of PPG ARE™ 3D Printed Sealants	Uniformity and Precision: One of the standout features of PPG’s 3D printed sealants is their ability to deliver a uniform application every time. The technology allows for the production of premixed and cured sealants that eliminate the variability associated with manual mixing and application. This precision is crucial in aerospace maintenance, where even minor discrepancies can lead to significant issues.	Time Efficiency: The installation time for sealants can be drastically reduced with PPG’s 3D printed solutions. Analysis of several applications has shown a 20% to 90% reduction in installation time, which helps maintenance teams work faster and more efficiently. This time savings can translate into reduced aircraft downtime, which is a critical factor in the highly competitive aerospace industry.	Customization: PPG’s 3D printed sealants are fully customizable to meet specific fitment demands. This flexibility is particularly beneficial in the aerospace sector, where various aircraft models have different sealing demands such as fuel seals, environmental seals, vibration dampening and pressure seals to name a few common areas. The ability to produce sealants tailored to the exact specifications of an aircraft helps ensure optimal performance and reliability.	Advanced Technology Integration: To achieve a consistent fit, PPG utilizes OEM CAD files for 3D printing. In cases where CAD files are unavailable, PPG employs laser scanning technology to accurately capture the dimensions of the sealant area. This capability ensures that even complex geometries can be accommodated, further enhancing the versatility of the 3D printed sealants.Benefits to the Aerospace Industry
The introduction of PPG ARE™ 3D printed sealant technology presents several potential advantages to the aerospace industry:
	 Enhanced Application: The technology allows for uniform and precise applications, which helps reduce the risk of deficient installations and the need for rework. This is paramount in the aerospace sector, where the integrity of every component is critical to the overall performance and safety of the aircraft.	Potential Cost Efficiency: By potentially decreasing installation time and minimizing material waste, this technology helps contribute to overall cost savings in maintenance operations. Additionally, the improved reliability of the sealants helps lead to lower maintenance costs over the lifecycle of the aircraft.	Sustainability: PPG's 3D printed sealants helping to promote more sustainable practices within the aerospace industry. By minimizing product waste and improving efficiency, this technology aligns with the industry's growing focus on environmental responsibility.Real-World Applications
PPG ARE™ 3D printed sealants are already making an impact in various aerospace applications. From commercial airlines to military aircraft, the technology is being adopted to streamline both the manufacturing and maintenance processes and improve the quality of sealant applications. Case studies have shown that operators using PPG's 3D printed solutions have experienced significant reductions in maintenance time and costs.
Conclusion
PPG's 3D printed sealant technology represents a significant advancement in the aerospace maintenance landscape. By addressing the challenges associated with traditional sealant applications, PPG is enhancing the efficiency and precision of  operations.  As the aerospace industry continues to evolve, innovations like PPG ARE™ 3D printed sealants will play a crucial role in shaping the future of aircraft manufacturing and maintenance.
