Aerospace Sealants – Preformed
Preformed Sealants Using PPG’s ARE™ Printing Technology.
Innovative 3D printed gaskets that provide an easy to apply, consistent and uniform application method.
Preformed Sealants
This revolutionary application method improves your sealant application by:Reducing installation time by up to 90%, eliminating bottlenecks in production or in-flight time.
Provides for consistent form, eliminating grinding or even rework. Hits the spec every time!
Increases your sustainability index by virtually eliminating all waste.
Decreasing supply chain issues – gaskets printed on demand
Traditional aerospace gaskets and sealants require extensive manual labor and rework. PPG’s preformed polysulfide and polythioether gaskets were created with aerospace engineers and technicians in mind and some have a national stock number (NSN). These preformed sealants eliminate the need to smooth sealant by hand, can be shipped on demand once designed and are proven to save our customers time and money.
PPG’s PRC® and Pro-Seal™ sealants have laid the foundation for aerospace manufacturing, maintenance and repair for the aerospace industry. PPG’s sealants are taking that excellence to the next level through creation of this innovative process that pre-forms sealants saving customers time and money.
Features & Benefits of Preformed Sealants
Rapid-cure
High-performance
Fuel-resistant (like PR-2001 that is tested to AMS 3277)
Maintain excellent elastomeric properties after prolonged exposure to organic fuels
Excellent resistance to water, alcohols, petroleum/synthetic lubricating oils and petroleum-based hydraulic fluids
Sealants available to pre-form are listed below. The PPG ARE production printer is large and adaptable. If you are using another product that you would like to explore creating preformed parts for, we are happy to partner with you. Contact us here and an expert will be in touch with you.

Manual Process vs. Automated Production:
PPG supplied Lockheed Martin with sets of custom-designed ramp seals for the aft loading ramp of the C-130J Super Hercules military tactical airlifter. PPG’s automated production yielded a greater than 30% customer cost savings and 10 times faster installation.
Our Process
To have a preformed part developed for your application, there are four simple steps to be followed:
Discovery Onsite visit to review the use case and laser-scan or mold the aircraft application area. PPG works with customers to identify opportunities that would benefit from pre-formed sealants.
Design Once scanned or molded, the part is created in CAD via reverse engineering or based on existing design. The part is then digitized and optimized for printing based on fit checks.
Prototype The part is sent to the customer for a fit check and any other additional testing. Additional iterations are captured, and the part iterates through Step 2 and 3 until the part is approved.
Production Delivery Production of the approved design is automated, and the part is printed and shipped directly to the customer. Once the design is approved, the part can be printed on demand at the customer’s convenience.
