What actually keeps an airplane sealed, aerodynamic, and safe—when the spotlight is usually on engines, wings, or pilots? In this episode of Adhesion Matters, we pull back the curtain on PPG's game-changing contributions to aerospace sealants and adhesives, revealing how essential—and innovative—these unsung materials truly are.

What You’ll Discover:

• The Silent Aerospace Enabler
  PPG plays a vital role across the aerospace lifespan—supplying not only adhesives and sealants, but also coatings, transparencies, and high-performance materials to OEMs, defense contractors, and MRO centers.
• More Than Materials—Complete Support
  From global training academies to design labs and application support centers, PPG pairs its products with deep technical guidance to ensure performance doesn’t just come off the shelf—it delivers in the hangar.
• 3D Printing Meets Precision Sealing
  Imagine sealants pre-printed in perfect shapes for fuel tanks, wing seals, cockpit areas, and more. PPG’s ambient reactive extrusion allows preformed seals to be rapidly deployed, slashing installation time by up to 90%—all with zero waste and unmatched consistency.
• Sealants Engineered for Extreme Conditions
  Whether it’s fast-curing polysulfides for fuel tank integrity or synthetics that resist +/- temperatures and vibration, these materials are engineered for safety. Electrically conductive sealants ensure shielding, smooth surfaces, and aerodynamic integrity at every junction.
• Lightweight, High-Strength Adhesion
  Structural adhesives like ESPAs bond and reinforce composite honeycomb panels—crucial for seats, galley doors, and overhead bins. They’re flame-retardant, cure at room temperature, and pack a high strength-to-weight ratio for optimal fuel efficiency.
• Precision, Skill & Application Matter
  Surface preparation, storage conditions, application technique, and cleanup routines are as critical as the sealants themselves—making expertise in usage just as vital as breakthrough chemistry.

Why It Matters:

This episode isn’t just about materials—it’s about invisible innovations that make modern flight possible. If you're fascinated by aerospace, precision engineering, or the science of performance and sustainability, this deep dive into PPG’s role will have you looking at the skies—and what's holding them together—very differently.
