FASTENINGS & ADHESIVES IBOA-FREE ADHESIVES FOR MEDICAL ELECTRONICS
Five new IBOA- and TPO-free adhesives have been added to DELO Industrial Adhesives medical electronics portfolio. DELO PHOTOBOND MG4202 is a colourless adhesive designed for structural bonds such
as housing bonding in wearables. This solvent-free, IBOA-free adhesive, cures in just one second at 1000mW/cm² LED intensity at 400nm with 100µm layer thickness. This operates across a temperature range of -40˚C to +125˚C. PHOTOBOND MG4191 is a versatile, multi-purpose solution, that is completely free of
skin-sensitising substances (H317-free) while maintaining high strength and flexibility. This lower-viscosity modification offers good water resistance and flow-resistant properties, making it ideal for various medical device applications. The complete portfolio includes three additional specialised variants: DELO PHOTOBOND
MG4094 provides fluorescent properties for visual process control; DELO PHOTOBOND MG4186 delivers peel resistance with high reliability; and DELO PHOTOBOND MG4164 combines blue fluorescence with sealing capabilities for FIPG and CIPG applications. All products meet stringent medical industry requirements, including biocompatibility
testing according to DIN EN ISO 10993-5 for cytotoxicity. They also comply with RoHS Directive 2015/863/EU and are available in convenient 30cc cartridges. The new adhesives complement DELO’s
existing medical portfolio, including the low- viscosity hydrophobic DELO PHOTOBOND MG4047 for potting applications in glucose monitoring sensors and other wearables, protecting underlying electronics from moisture and sweat. Together, these solutions address the
increasing convergence of medical and consumer electronics industries, particularly in wearable medical devices, biosensors, and advanced monitoring systems where both performance and patient safety are critical.

FLEXIBLE ULTRASONIC WELDING PLATFORM INTRODUCED
The Branson Polaris Ultrasonic Welding Platform from Emerson enables advanced manufacturing engineers to design efficient joining solutions with software and hardware. The Polaris platform is an adaptable, smart solution, with secure connectivity
across the factory floor and real-time control capability to join a wide range of materials and components, including automotive parts, medical devices, consumer electronics, food packaging, appliances, bioplastics and textiles. “Today’s manufacturers need ultrasonic welding systems that are as
adaptable and advanced as they are. They need an automated platform that seamlessly integrates into manufacturing environments and can be updated over time to align with changing requirements,” said Kerryn Harrington, global product manager for Branson Ultrasonics at Emerson. “In response, Emerson engineers designed the Branson Polaris Ultrasonic Welding Platform as a configurable scalable solution. That meets exacting needs across a wide range of applications – from simple components to FDA-approved products – now and in the future, anchored in Emerson’s standing as the foremost authority in essential ultrasonic welding methods used by major manufacturers worldwide.” The Polaris platform consists of power supplies and controllers
with varying degrees of functionality and software capabilities, as well as a line of actuators that can be selected to meet the needs of any application, regardless of size and complexity. These technologies can be combined to build a benchtop
machine for development, laboratory trials and proof of concept, then scaled
up for use in a fully automated production line. The platform can connect to higher level systems such as programmable logic
controllers (PLCs) for improved efficiency, reliability and precision. Emerson

Solfre PressSmart from Chemique Adhesives is a three- component (3C) polyurethane adhesive system designed to maximise efficiency, improve flexibility, and ensure consistent output in sandwich panel manufacturing. This consists of two Part A components and a single
Part B hardener. The two Part A components contain different catalyst levels – one fast-curing and one slow-curing – providing manufacturers with the ability to adjust processing times in real time and maintain consistent results regardless of ambient temperature. By varying the blend ratio of the fast- and slow-curing Part A components during application, manufacturers can precisely control open time, press time, and total cure time, to match production requirements. Automated application equipment precisely mixes
the two Part A components at the required ratio. This provides a wide processing window, with open times ranging from ten to 100 minutes and total cure times from 30 to 300 minutes, enabling reliable adhesive performance in both hot and cold environments. For even greater production efficiency, Solfre
PressSmart allows ratios to be adjusted between adhesive coats. Increasing the proportion of the fast- curing Part A component in later coats shortens press times without affecting open time or handling characteristics. For example, a panel that typically requires 180 minutes in the press when using a conventional Solfre adhesive (with a 60-minute open time) can be cured in approximately 120 minutes when processed with Solfre PressSmart, significantly improving cycle time and throughput. “Solfre PressSmart marks a significant step forward
for panel manufacturers who require both accuracy and flexibility,” commented Stuart Francis, managing director of Chemique Adhesives. “The three-part system delivers precise control of open and press times, allowing for consistent processing times across a range of temperatures. This enables manufacturers to maximise throughput while maintaining the highest quality standards.”
