Intertronics introduces medical wearables adhesives and encapsulants
To help manufacturers of wearable devices adapt to industry trends and customer requirements, adhesives and dispensing equipment specialist Intertronics has introduced the Dymax 2000-MW series of medical wearables adhesives and encapsulants. The series is said to be the first dedicated, light-curable adhesive product line to be specifically formulated without common skin irritants and materials of concern for medical wearable and electronics applications
A
ll adhesives in the range are compliant with ISO 10993-5 for cytotoxicity, with some grades available that also meet ISO10993-10 for sensitisation
and irritation. Notably, all materials in the 2000- MW range are formulated without isobornyl acrylate (IBOA), a known skin irritant, and TPO, a
a wide range of products, including smart monitoring devices such as continuous glucose monitors, pain management devices, sleep monitoring products, and hearing aids, alongside many others.
“Any products that come into proximity with the skin are under increased scrutiny,” explained Ben Swanson, sales manager at Intertronics. “In the highly regulated and rapidly growing wearables market, manufacturers can future-proof their products and avoid costly product recalls and redesigns by choosing adhesives that they know to be safe and compliant with relevant
photoinitiator and material of concern. Light curable materials bring a whole host of process and cost advantages during wearable device assembly. These adhesives cure in seconds “on demand” on exposure to the correct wavelength of visible and/ or UV light, increasing throughput, reducing work in progress and reducing costs. A 100 per cent solids, 100 per cent solvent-free, single part formulation simplifies and reduces cost of handling, processing, and dispensing, while minimising environmental impact and improving worker safety.
Applications include coating and encapsulation of RFID chips or sensor housing assemblies, as well as wire and flex tracking, needle-to-hub bonding, and general assembly bonding. The materials form a reliable bond to many commonly-used plastics and have dependable performance against moisture and shock, and can therefore be considered for

regulations. This new Dymax series of adhesives gives manufacturers some additional peace of mind that the product will be safe for users.”
Intertronics offers two formulations in the series. Dymax 2101-MW-UR is ideal for the general bonding of medical wearables, offering strong adhesion to a variety of substrates including PC, PVC, and TPU. It also features patented Ultra-Red fluorescing technology for instant in-line quality control. Dymax 2022-MW is a versatile general bonding adhesive, coating, and electronics encapsulant with minimised water ingression and extremely low water absorption of 0.5 per cent. It bonds well to stainless steel, aluminium, glass and PCBs.

Award-Winning OKW CONTROL-KNOBS For Menu-Driven Electronics
OKW’s elegant rotary/click CONTROL-KNOBS have won an iF Design Award 2022. Hailed as “perfect all round”, they now feature a new, improved design with greater illumination (option).
The iF DESIGN AWARD is one of the most important design prizes in the world. For 65 years, designers and manufacturers have worked to win the internationally renowned iF label.
Ergonomic CONTROL-KNOBS are ideal as the central element for menu-driven electronics – typically
for devices manufactured in high volumes. Applications include measuring and control; medical, wellness and laboratory technology; HVAC; communications; Smart Factory and building control systems.
These soft-touch tuning knobs fit rotary potentiometers or encoders with round shaft ends (DIN
41591). Illumination is via SMD LED technology (5 V). RGB LEDs allow individual lighting and colours, illuminating a translucent optic ring on the top. OKW has increased the number of LEDs on the larger knobs from eight to 12. (The smaller knobs have eight LEDs).
The knobs can be specified with or without a pointer line on the side. They fit securely on
potentiometer spindles, using the tried and tested collet fixture system. The maximum torque for installation is 1.5 Nm (function 1.2 Nm).
Each knob comprises two parts – a hard inner body made of robust polycarbonate and a soft-touch
TPE outer shell with a smart and practical grooved appearance. They are available in two sizes: ø 36 mm and ø 46 mm (boreholes 6 mm, 1/4”). The standard colours are nero black and volcano grey.
Accessories include LED illumination kits, bases, covers, round nuts and a spanner.
OKW can supply CONTROL-KNOBS fully customised. Services include CNC machining, printing, laser marking and installation/assembly.
