Seamless Sealing: Henkel’s Sonderhoff FIPFG Foam Gasket Technology

What if seals could be created directly on your part—no cutting, no insertion, no seams? In this episode of Adhesion Matters, we dive into Henkel’s Sonderhoff Formed-in-Place Foam Gasket (FIPFG) technology, a system that applies liquid foam directly onto components where it cures into seamless, precise, and highly resilient gaskets. We explore how polyurethane systems like FERMAPOR K31 and silicone foams like FERMASIL are transforming sealing in industries ranging from electronics enclosures and automotive modules to household appliances and e-mobility charging stations. Beyond technical performance, we highlight how FIPFG advances sustainability—eliminating waste from punched gaskets, reducing energy with room-temperature curing, and offering long service life through exceptional compression recovery. We also examine the role of automation and robotics in enabling consistent, scalable application. Whether you’re an engineer, product designer, or operations manager, this episode shows why the future of gasketing is being shaped—in place.

Sealing the Smallest Molecule: Adhesives for Hydrogen & Fuel Cells

How do you seal the most elusive molecule in the universe? In this episode of Adhesion Matters, we explore the unique role adhesives and sealants play in the hydrogen economy. From membrane–electrode assemblies (MEAs) in fuel cells to valves, pipelines, and high-pressure tanks, hydrogen’s small size creates extraordinary challenges: permeation, embrittlement, and cyclic fatigue. We highlight sealant chemistries that can stand up to these demands—including silicones, fluorosilicones, and hybrid polymers—and explain how companies like Dow and Henkel are engineering hydrogen-ready sealing solutions. We also dive into ISO and SAE test standards that define allowable leak rates and durability benchmarks, and look ahead at innovations such as self-healing sealants and seal-in-place gasketing.   Whether it’s cars, trucks, ships, or stationary power, hydrogen fuel cells depend on adhesives that keep the smallest molecule safely under control. This episode shows how the right chemistry is critical for scaling the hydrogen future.

Sticking Safely: Medical PSAs, Biocompatibility, and ISO 10993

Why must a medical adhesive stick—and then let go—without harming the skin?  In this episode of Adhesion Matters, we dig into the science—and the sticky business—behind pressure-sensitive adhesives (PSAs) designed for everything from surgical dressings and wearables to wound care patches. We compare key chemistries—silicones, acrylics, and hydrogels—and show how each serves specific medical purposes like temperature resistance, conformability, or moisture management. We break down the rigorous ISO 10993 standards for biocompatibility, including critical tests for cytotoxicity, sensitization, and irritation. We also spotlight how companies like Dow and Henkel navigate those standards while enabling modern device manufacturing through UV-cure imaging and fast assembly. Finally, we look ahead to what’s next: from bioresorbable adhesives and smart, medication-releasing patches to PFAS- and solvent-free formulations—showing how the next wave of medical adhesives aims to stick safely while innovating boldly. Whether you're a materials engineer, regulatory specialist, or just fascinated by where adhesives intersect with healthcare, this episode reveals how smart chemistry keeps us safer—and more comfortable—on the skin.

Adhesives at Sea: Structural Bonding and Safety in Modern Shipbuilding

Welcome back to the Adhesion Matters podcast. How do adhesives survive salt spray, constant shock, and the world’s toughest fire standards? In this episode, we dive into the unique challenges of marine and shipbuilding applications. From composite superstructures and deck bonding to corrosion-resistant sealing, adhesives are now replacing welds and rivets in some of the harshest environments on earth. We highlight some epoxy adhesies for structural bonding, along with silicone sealants that deliver fire resistance and weather durability in line with IMO safety codes. Finally, we look ahead at the role adhesives will play in greener shipping—hydrogen ferries, lightweight composites, and wind-assisted propulsion. Whether you’re a naval architect, shipyard engineer, or materials specialist, this episode shows how modern adhesives keep the world’s fleets lighter, safer, and ready for the future.

From Heat to Miniaturization: How Adhesives Are Reinventing PCB Manufacturing

Welcome back to Adhesion Matters. Adhesives have quietly evolved from simple bonders into indispensable, high-performance materials in PCB manufacturing—critical for thermal management, electrical performance, and environmental resilience.  In this episode, we explore how adhesives empower modern electronics: enabling miniaturization, supporting flexible and high-density circuits (think HDI and flex PCBs), and meeting rising demands in consumer tech and electric vehicles. You’ll discover how specialized adhesive families—epoxies, acrylics, silicones, polyamides, polyurethanes—each offer unique strengths, from rigidity and heat-resistance to flexibility, reworkability, and flame protection. Hear how engineers tailor selections based on criteria like thermal conductivity, environmental durability, and the ability to withstand mechanical or thermal stress over time. Learn about real-world applications across the PCB manufacturing spectrum: surface mount adhesive placement, underfills, die attaches, conformal coatings, potting compounds, encapsulants, and even thermal interface materials that control heat in EV power systems. Finally, we look ahead at the future of adhesive innovation: extreme miniaturization, advanced thermal management for EVs, and a push for eco-friendlier, halogen-free, low-toxicity formulations.
